Absolutely stable time crystals at finite temperature
Francisco Machado, Quntao Zhuang, Norman Y. Yao +1
We show that locally-interacting, periodically-driven (Floquet) Hamiltonian dynamics coupled to a Langevin bath support finite-temperature discrete time crystals (DTC) with an infi…

Scalable Spin Squeezing from Finite Temperature Easy-plane Magnetism
Maxwell Block, Bingtian Ye, Brenden Roberts +7
Spin squeezing is a form of entanglement that reshapes the quantum projection noise to improve measurement precision. Here, we provide numerical and analytic evidence for the follo…
