DESCRIPTION:Speakers: Dongwook Ghim\n\nIn this talk\, I will review a rece
 nt paper by Huang\, Komargodski\, Lucas\, Popov\, and Sulejmanpasic\, on t
 he concept of entropic order. \nWe typically expect simple thermodynamic 
 systems\, like the Ising model\, to exhibit an ordered phase at low temper
 atures and a disordered phase at high temperatures. This familiar pattern 
 is governed by the free energy F = E - TS\, which is minimized at high-T b
 y maximizing the entropic contribution with disorder. However\, entropic o
 rder presents an interesting loophole behind this argument. In certain phy
 sical systems\, a high-T ordered phase emerges through a trade-off: freezi
 ng one local degree of freedom facilitates another to fluctuate more wildl
 y. As a consequence\, the system maximizes its overall entropy by showing 
 a "checkerboard" or solid-like ordered structure\, where translational sym
 metry is spontaneously broken. As the simplest example\, I will review th
 e arithmetic Ising model (AIM) in this talk. If time permits\, I will also
  discuss the historic & potential phenomenological applications of the con
 cept. \nThe main reference is: https://arxiv.org/abs/2512.07980.\n \n\nh
