Why do so many black holes measured in gravitational waves have zero spin?
Black hole entropy is a robust prediction of quantum gravity with no established phenomenological consequences to date. We use the BekensteinHawking entropy formula and generalrelativistic statistical mechanics to determine the probability distribution of random geometries uniformly sampled in phase space. We show that this statistics (in the limit \( \hbar \to 0\) ) is relevant to large curvature perturbations, resulting in a population of primordial black holes with zero natal spin. In principle, the identification of such a population at LIGO, Virgo, and future gravitational wave observatories could provide the first observational evidence for the statistical nature of black hole entropy.Contact Information: Prof. L.

Advances in the Exploration of the Nucleon Resonance Spectrum and Structure in Experimentswith CLAS and CLAS12
Studies of nucleon resonances (N*) in experiments with electromagnetic probes offer unique information on many facets of the strong interaction in the regime of large (on the order of unity) QCD running couplings seen in the generation of the spectrum of N* states with different quantum numbers and structural features. The current status of the N* spectrum and structure studies for exclusive meson photo and electroproduction data with CLAS at Jefferson Lab will be presented in the talk. The extension of these efforts in the Jefferson Lab 12 GeVera experiments with CLAS12 will be outlined.

Phase diagram of QCD and Lifshitz regime: how transverse thermal fluctuations might turn nuclear matter into quantumspin liquid
We discuss dense cool QCD where a region with spatially inhomogeneous condensate might emerge. In that case, QCD phase diagram may exhibit a Lifshitz regime, which can appear either instead of, or in addition to Critical End Point. We study the Lifshitz regime using a combination of largeN expansion and numerical lattice simulations of an effective O(N) sigma model. We find evidence that quantum fluctuations disorder inhomogeneous condensate ("chiral spirals") and give rise to unusual quantum spinliquid phase. We also discuss how this novel phase can be detected experimentally.
