Abstract: Dark Matter remains a profound mystery at the intersection of particle physics, astrophysics, and cosmology. While searches have made significant progress, particularly for dark matter in the form Weakly Interacting Massive Particles, or...

Abstract: Flocks and swarms are iconic examples of living matter, in which motile, interacting individuals give rise to emergent global patterns. Despite the complexity of their biological components, these groups obey robust statistical laws and...

Abstract: It is well-known that the Hilbert space of a quantum field theory does not factor into a tensor product of degrees of freedom in a region and its complement. Nevertheless, the split property guarantees that there exists a factorization...

Abstract: Self-interacting dark matter (SIDM) is a well-motivated extension of ΛCDM that can alter the inner structure of haloes via collisional heat transport. It has been explored as a possible solution to small-scale tensions such as the cusp-...

Abstract: For a quantum field of arbitrary mass and spin in the static patch of de Sitter spacetime, the Euclidean partition function receives contributions from edge modes localized on the horizon, expressible in terms of the Harish-Chandra...

Abstract: Extremal horizons (and associated emergent quantum criticality of the corresponding holographic models) receive strong quantum corrections at very low temperatures.  We point out that when such models are embedded in top-down holography...

Abstract: How well can an observer making local measurements learn about global properties of a system, e.g., its charge? I will motivate this question in the quantum setting, and then turn to some results on classical stochastic processes. I will...

Abstract: Topological defects in the N=1superconformal minimal models are constructed using their coset description. These topological defects are then used to constrain the possible RG flows of the N=1 superconformal minimal models. I will also...

Abstract: Axions are some of the best-motivated beyond the Standard Model particle candidates at present. These ultralight particles may account for the cosmological dark matter and explain other outstanding problems in nature, such as the strong-CP...
