SUMMARY:Physics Colloquium: Zhiyue Lu
DESCRIPTION:Title: Mathematical Foundation and Extension of Statistical Mechanics\nAbstract:  How can simple macroscopic laws emerge from the chaotic motion of astronomically many microscopic degrees of freedom? Statistical mechanics answers this question with a mathematical structure of striking simplicity\, built around entropy\, Boltzmann weights\, and free energy. In this colloquium\, I will revisit why that structure appears and why it is so universal. Using simple examples from probability\, gases\, and random walks\, I will argue that equilibrium statistical mechanics is fundamentally a theory of counting\, additivity\, and typicality. I will then show how the same logic can be extended beyond equilibrium by shifting attention from probabilities of states to probabilities of entire dynamical trajectories. This broader viewpoint provides a natural language for irreversibility\, entropy production\, and modern fluctuation relations. The emphasis will be on concepts rather than technical detail\, with the goal of giving a broad physics audience a unified picture of how statistical mechanics is founded and how it continues to evolve.

SUMMARY:Physics Colloquium: Kenan Gundogdu
DESCRIPTION:Title: Rethinking Superfluorescence: A Window into Macroscopic Quantum Order \nAbstract: Macroscopic quantum coherence is typically associated with low temperatures\, where thermal fluctuations do not rapidly destroy phase correlations. In solids\, however\, electronic coherence is strongly influenced by lattice dynamics\, making it unclear how collective quantum states can persist at elevated temperatures.  \nIn this talk\, I will show how studies of superfluorescence provide a powerful window into the emergence of macroscopic coherence in condensed matter systems. By tracking the buildup of collective emission in lead-halide perovskites\, we find that superfluorescence does not originate from simple radiative synchronization of independent dipoles. Instead\, it reflects the formation of an underlying many-body excitonic state\, shaped by strong exciton–lattice interactions. Our results reveal a general mechanism in which lattice dynamics actively reorganize the electronic landscape\, enabling the emergence of coherent excitonic order at high temperatures. This perspective establishes superfluorescence as a diagnostic of nonequilibrium phase transitions and points to a broader principle for achieving macroscopic quantum coherence in strongly interacting systems. \n

SUMMARY:Physics Colloquium: Daphne Klotsa
DESCRIPTION:Title: Making a Splash and Mixing It Up in Active Matter \nAbstract: Living matter\, such as biological tissue\, can be viewed as a nonequilibrium hierarchical assembly in which self-driven components consume energy to organize into increasingly complex structures across scales. These living\, or “active-matter\,” systems exhibit remarkable properties such as adaptability\, self-healing\, and self-organization\, raising fundamental questions about the underlying physics and whether similar functionality can be engineered in synthetic materials and other systems\, including robots and drug-delivery particles. In this talk\, I will focus on two classes of active systems that remain surprisingly unexplored: active matter in fluids with finite inertia and multicomponent active colloidal mixtures. I will present recent results showing novel emergent phase behavior and discuss their implications for materials design and technological applications.
