Non-perturbative saturation of Krylov complexity, and its implications in quantum gravity
Andrew Lucas, Amit Vikram
The paper investigates Krylov state complexity in finite-dimensional quantum systems, showing it saturates shortly after the Heisenberg time for low‑energy states, and discusses th…
Minimal Models of Entropic Order
Xiaoyang Huang, Zohar Komargodski, Andrew Lucas +2
Due to entropic effects, it is possible that generic high-energy states of a quantum or classical system are ordered. This leads to spontaneous symmetry breaking at arbitrarily hig…
On the reconstruction map in JT gravity
Chris Akers, Andrew Lucas, Amit Vikram
An open question in AdS/CFT is how to reconstruct semiclassical bulk operators precisely enough that non-perturbative quantum effects can be computed. We propose a set of physicall…
Entropic Order
Yiqiu Han, Xiaoyang Huang, Zohar Komargodski +2
Ordered phases of matter, such as solids, ferromagnets, superfluids, or quantum topological order, typically only exist at low temperatures. Despite this conventional wisdom, we pr…
Hydrodynamics as the effective field theory of strong-to-weak spontaneous symmetry breaking
Xiaoyang Huang, Marvin Qi, Jian-Hao Zhang +1
Inspired by the hunt for new phases of matter in quantum mixed states, it has recently been proposed that the equivalence of microcanonical and canonical ensembles in statistical m…
Breakdown of hydrodynamics in a Galilean quantum Hall crystal
Xiaoyang Huang, Andrew Lucas
We construct a nonlinear fluctuating hydrodynamic effective field theory for Galilean-invariant quantum Hall systems with spontaneously broken translational symmetry. Neglecting th…
