Thermal order in large N conformal gauge theories
Soumyadeep Chaudhuri, Changha Choi, Eliezer Rabinovici
In this work we explore the possibility of spontaneous breaking of global symmetries at all nonzero temperatures for conformal field theories (CFTs) in space-time dimension…
Pole skipping away from maximal chaos
Changha Choi, Márk Mezei, Gábor Sárosi
Pole skipping is a recently discovered subtle effect in the thermal energy density retarded two point function at a special point in the complex planes. We propose that pol…
Thermal Order in Conformal Theories
Noam Chai, Soumyadeep Chaudhuri, Changha Choi +3
It is widely expected that at sufficiently high temperatures order is always lost, e.g. magnets loose their ferromagnetic properties. We pose the question of whether this is always…
Exact four point function for large SYK from Regge theory
Changha Choi, Márk Mezei, Gábor Sárosi
Motivated by the goal of understanding quantum systems away from maximal chaos, in this note we derive a simple closed form expression for the fermion four point function of the la…
Phases of Two Adjoints QCD And a Duality Chain
Changha Choi
We analyze the 2+1 dimensional gauge theory with two fermions in the real adjoint representation with non-zero Chern-Simons level. We propose a new fermion-fermion dualities betwee…
New and Old Fermionic Dualities from 3d Bosonization
Kyle Aitken, Changha Choi, Andreas Karch
We construct novel fermion-fermion dualities in -dimensions using 3d bosonization dualities. This is achieved by relating two-node quiver theories using both the flavor-bounde…
