Abstract: Consider the interaction of one-dimensional surface gravity waves on top of an ideal fluid of infinite depth. Notably, for certain orientations of the wave vectors, the interaction matrix element vanishes, while for other orientations, the...

Abstract: This talk will discuss what's new with some of the most interesting looking cosmological tensions: the Hubble tension, the growth of structure tension (S8, growth rate, Lyman Alpha) and Big Bang Nucleosynthesis (Lithium and Deuterium)...

Abstract: We will start with a review of previous results concerning  instabilities of rotating Kerr black holes to massive scalar field perturbations. These instabilities are connected to superradiance and hence do not occur on the Schwarzschild...

Abstract: Quantizing classical systems we consider Hilbert spaces equipped with representations of canonical commutation relations (CCR).  In the case of an infinite number of degrees of freedom it is necessary to consider representations of  CCR...

Abstract: Conformal field theories that exhibit spontaneous breaking of conformal symmetry (a moduli space of vacua) are expectedly rare in the landscape of CFTs. Intuitively, this is because a delicate conspiracy is needed to fine-tune to zero the...

Abstract: The Council of CERN is responsible for formulating the scientific and financial policy of CERN. It does this with strong coordination with the CERN Director General and Management. I will describe how the CERN Council reaches its decisions...

Abstract: In this talk I review the identification between quantum states in 3D AdS gravity and Virasoro blocks in 2D CFT and describe the inner product on the space of conformal blocks. I comment on the possible application of these results to de...

Abstract: I will present some questions and answers regarding the duality between 1+1-dimensional superconformal field theory and type II string theory on $AdS_3 \times S^3 x T^4$.

For one unit of NS-NS 5-brane flux ($Q_5$=1), this string theory has...

Abstract: In the pursuit of Beyond the Standard Model (BSM) physics, the CMS experiment has employed unconventional techniques to uncover elusive phenomena. This presentation delves into three pivotal aspects of this effort during LHC Run-2 and the...
