Abstract: Khuri, in 1995, considered potential scattering for a model where one spatial coordinate in compactified on the circle. He adopted Greens function method to study analyticity property of scattering amplitude. His conclusion was that...

Abstract: I will briefly review the black hole information paradox in the powerful formulation of Almheiri, Marolf, Polchinski and Sully. I discuss some challenges for complexity-protected black hole complementarity. I suggest a covariant definition...

Abstract: Dark matter is a hypothetical matter in the universe introduced to coherently explain observations ranging from the scale of galaxies to the whole of the universe. The DarkSide program is a direct dark matter detection experiment that...

Abstract: Cross-section predictions are crucial for the success of long-baseline neutrino experiments, but they suffer from significant theoretical uncertainties. Given the promise of future near detector data, one certainly expects and needs to...

Abstract: The accelerated expansion of the universe leads to a horizon beyond which we cannot see.  Structure arises from the quantum variance of early universe fields stretched across the horizon, according to the simplest theory fitting...

Abstract: I will present upcoming linear and non-linear stability results concerning the asymptotic behavior of collisionless many-particle systems on black hole exteriors. On the one hand, I will discuss the decay properties of massive Vlasov...

Abstract: More than twenty years ago, in an experiment at Brookhaven National Laboratory, physicists detected what seemed to be a discrepancy between measurements of the muon’s magnetic moment and theoretical calculations of what that measurement...

Abstract: I will discuss the reasoning behind the suggested connection between double-scaled SYK (DSSYK) and de Sitter space. We will mention the general form of the correspondence as well as the mapping of parameters between the two sides. On the...

Abstract: Recently, I have been trying to understand how large language models (LLMs) work, what their basic building blocks are and how they are trained. In this talk I want to share some of my understanding with you by discussing the so-called...

Abstract: Tidal deformation is a significant phenomenon observed in various astronomical scenarios, including black holes, and are a key gravitational-wave observable encoding information about the object's interior. Relying on hidden symmetries...
