sciforum-042409	Gravitational Collapse in 4D-Einstein Gauss-Bonnet Gravity Omia Masood , Hasrat Shah , Hassan Shah , Alibek Issakhov , Syed Abbas Submitted: 15 Jan 2021 Abstract: Show Abstract	Omia Masood , Hasrat Shah , Hassan Shah , Alibek Issakhov , Syed Abbas	N/A	N/A	Show Abstract
We investigate the gravitational collapse of a gravitational bounded object constituted of dust cloud and dark energy. We considered the the effects of homogenous and isotropic fluid on newly suggested 4D limit for Einstein-Gauss-Bonnet gravity(EGB) (For detail about EGB gravity, arXiv:1905.03601v3). For this purpose, we consider the gravitational collapse of gravitational object made of dust cloud ρ_DMin the background of dark energy, p = wρ with (w < −1/3). We illustrate that the procedure is qualitatively equivalent to the scenario of theory of Einstein for the collapse of the gravitational object composed of homogeneous dust. Further, we consider the collapse for dark energy by considering the equation of state p = wρ to find that black hole also may form in EGB case, which predict that end state of gravitational collapse in EGB case is consistent with results carried out in pure Einstein’s gravity theory. We have discussed two separate case, first, gravitational collapse of dust cloud in the context of EGB, in the second case, gravitational collapse of dark energy in EGB background. It is found that, gravitational collapse leads to formation of black hole in both cases. It is also worth mentioning that, end state of gravitational collapse in EGB context is same as in pure Einstein's gravity. Here, in this study dark matter refer to dust cloud, a matter with zero pressure.
sciforum-037373	Existence and Stability of Static Spherical Fluid Shells in a Schwarzschild-Rindler-anti-de Sitter Metric George Alestas , Leandros Perivolaropoulos , George Kraniotis Submitted: 19 Sep 2020 Abstract: Show Abstract	George Alestas , Leandros Perivolaropoulos , George Kraniotis	N/A	N/A	Show Abstract
Shells of matter sources with zero thickness play an important role in both electromagnetism and general relativity. They provide a useful laboratory for the exploration of new phenomena while at the same time they approximate smooth solutions such as domain walls . Thin shells are also useful in describing gravitational collapse or in constructing spherically symmetric vacuum solutions that avoid the presence of singularities. We demonstrate the existence of static, stable and thin spherical fluid shells in the Schwarzschild-Rindler-anti-de Sitter (SRAdS) spacetime. This provides us with an alternative to the well-known gravastar geometry where the stability emerges due to the combination of the repulsive forces of the interior de Sitter space with the attractive forces of the exterior Schwarzschild spacetime. In constrast, when it comes to the SRAdS spacetime, the repulsion that leads to stability of the shell comes from a negative Rindler term while the Schwarzschild and anti-de Sitter terms are attractive. We demonstrate the existence of such stable spherical shells for three cases of fluid shells with the appropriate equations of state, i.e. vacuum shell, stiff matter shell, and dust shell. To do so, we also identify the metric parameter conditions that need to be satisfied in order to have shell stability in each case. The vacuum stable shell solution in the SRAdS spacetime is consistent with previous studies by two of the authors that demonstrated the existence of stable spherical scalar field domain walls in the SRAdS spacetime.
sciforum-041895	Second Order Glauber Correlation of Gravitational Waves using the LIGO observatories as Hanbury Brown and Twiss detectors Alexander Barrett , Preston Jones Submitted: 15 Dec 2020 Abstract: Show Abstract	Alexander Barrett , Preston Jones	N/A		Show Abstract
In this paper the second order Glauber correlation of a simplified gravitational wave is investigated, using parameters from the first signal detected by LIGO. This simplified model spans the inspiral, merger, and ringdown phases of a black hole merger and was created to have a continuous amplitude, so there is no discontinuity between the phases. This allows for a trivial extraction of the intensity, which is necessary to determine the correlation between detectors. The two LIGO observatories can be used as detectors in a Hanbury Brown and Twiss interferometer for gravitational waves, these observatories measure the amplitude of the wave, so these measurements were used as the basis of the simplified model. The signal detected by the observatories is transient and is not consistent with chaotic or steady electromagnetic waves and thus the second order Glauber correlation function was calculated to produce physically meaningful results. A correlation was also calculated using a sine-Gaussian model in hopes to describe the waveform in an even simpler model. To find correlations that are consistent with applications to electromagnetic waves weighting functions for both models were studied in the integral equations for the Glauber correlation functions. The relationship between the transient and chaotic signals of both waveforms and their respective correlation functions was also examined. The second order Glauber correlation functions are a measure of intensity interference between independent detectors and has proven to be useful in both optics and particle physics. It has also been used in theoretical studies of primordial gravitational waves. The correlations can be used to define the degrees of coherence of a field, characterize multi-particle processes, and assist in image enhancement.
sciforum-042529	Interactive applications to teach the Einstein's Energy-Momentum-Mass relation in the secondary school. Lorenzo Galante Submitted: 04 Jan 2021 Abstract: Show Abstract	Lorenzo Galante		N/A	Show Abstract
Two Geogebra-based interactive applications to teach the Special Relativity Energy-Mass-Momentum relation are presented. They are useful tools to visualise from a geometrical perspective the mathematical relation, thus helping students facing calculus difficulties to understand the beauty of this equation. They also give students the opportunity to carry out explorations and come to conclusions. They allow us to inquire the meaning of the p/E ratio for particles with different masses and energies, to discover that a system with a given finite mass and increasing energy travels at a speed approaching a finite value. Even the relativistic meaning of the mass of a system of particles can be addressed with these applications. Students can discover that the relativistic mass is different from the mere sum of the masses of the system, that is always greater than or equal to the sum of the masses, that it depends on the momenta directions, that is equal to the sum of the masses if all the particles of the system are at rest. Since these concepts are crucial for the understanding of how particles are discovered in Particle Physics, the two applications open the way to introduce students to the main aspect of modern research in Nuclear and Accelerators Physics.
sciforum-042629	New perspectives for multifrequency GW astronomy: strong gravitational lensing of GW Aleksandra Piórkowska-Kurpas Submitted: 07 Jan 2021 Abstract: Show Abstract	Aleksandra Piórkowska-Kurpas	N/A	N/A	Show Abstract
Direct detection of gravitational waves was for a long time a holy grail of observational astronomy. The situation changed several years ago with the first ever laboratory detection of gravitational wave signal on the Earth (GW150914), showing once again that Einstein was right. Now, successful operating runs of LIGO/Virgo gravitational wave detectors, resulting with numerous detections of gravitational wave signals from coalescing double compact objects (mainly binary black hole mergers) with the first evidence of coalescing binary neutron star system, elevated multimessenger astronomy to the unprecedented stage. Double compact objects (binary black hole systems, mixed black hole-neutron star systems and double neutron star systems) are the main targets of future ground based and space-borne gravitational wave detectors opening the possibility for multifrequency gravitational wave studies and yielding very rich statistics of such sources. This, in turn, makes possible that certain, non-negligible amount of double compact objects will have a chance of being strongly lensed. In this presentation I will discuss new perspectives for future detections of gravitational wave signals in the case of strong gravitational lensing. First, the expected rates of lensed gravitational wave signals will be presented. Multifrequency detections of lensed gravitational wave events, will demand different treatment at different frequencies, i.e. wave approach vs. geometric optics approach. I will discuss new possibilities emerging from such multifrequency detections.

S8. The Universe of Andrei Sakharov

In 2021, we will commemorate the 100th anniversary of the birth of Andrei D. Sakahrov, and UNESCO has nominated this year A.D. Sakharov year. The paper "Cosmoparticle Physics as Cross-Disciplinary Science" was the last in the list of Sakharov's publications, so studies of the fundamental relationship of cosmology and particle physics further developed his scientific legacy.

Sakharov conditions in baryosynthesis, Sakharov oscillations in CMB, and Sakharov enhancement in dark matter annihilation are but a few examples of A.D. Sakharov’s legacy in the modern theory of the Universe. The aim of this session is to discuss the place and prospects of the development of Sakharov's legacy in studies of the mutual relationship of the bases of modern particle physics and cosmology, as well as the nontrivial features of its indirect physical, cosmological, and astrophysical probes. Such features involve but are not limited to models of the very early Universe and their observational signatures, physics of dark matter, and its direct and indirect probes, as well as to a wide range of models beyond the standard models of particle physics and cosmology and their effects.

Keywords: cosmology; particles physics; astroparticle physics; cosmoparticle physics; BSM models; dark matter; inflation; baryosynthesis; supergravity; extra dimensions

S9. Teaching Relativity and Modern Physics in General

General relativity describes the interplay between the geometry of space-time and its matter and energy content; together with quantum mechanics, on which the standard model of particle physics is based, they represent a best understanding of our universe and of fundamental interactions. Both theories have their roots in the works published by Einstein in his miraculous year, 1905: accordingly, we may refer to modern physics as Einsteinian physics. General relativity and quantum mechanics, besides having an outstanding importance for science, influence our everyday life because of their impact on our technology, such as, for instance, GPS and mobile devices. Despite all this, the Newtonian concepts of space and time, which are in conflict with the modern physics approach, are still largely taught in schools worldwide.

In this session, we will discuss the necessity and possibility of teaching Einsteinian ideas across Years K–12, to give students a better awareness of the modern understanding of our universe. Contributions addressing good practices in teaching modern physics from primary to secondary schools are welcomed.
