𝐓𝐢𝐭𝐥𝐞: Entropic Order
𝐒𝐩𝐞𝐚𝐤𝐞𝐫: Fedor Popov, Simons Center for Geometry and Physics, Stony Brook University
𝐀𝐛𝐬𝐭𝐫𝐚𝐜𝐭:
Ordered phases of matter, such as solids, ferromagnets, superfluids, or quantum topological order, typically only exist at low temperatures. Despite this conventional wisdom, I will present explicit local models in which all such phases persist to arbitrarily high temperature. This is possible since order in one degree of freedom can enable other degrees of freedom to strongly fluctuate, leading to "entropic order", whereby typical high energy states are ordered. Our construction, which utilizes interacting bosons, avoids existing no-go theorems on long-range order or entanglement at high temperature. I will also review known results on ordered states and introduce a simple model that realizes high-temperature superconductivity within this framework.

Fedor Popov is a theoretical physicist and Research Assistant Professor at the Simons Center for Geometry and Physics (Stony Brook University). His research explores quantum field theory, conformal defects, and large N dynamics, bridging mathematical structures and physical phenomena. He has contributed to understanding entropic order, symmetry breaking, and emergent geometry in strongly correlated systems. He received his PhD from Princeton University in 2021 and was a Simons Junior Fellow at NYU from 2021 to 2024.
