Infinite-temperature quantum phases and phase transitions
Tengzhou Zhang, Zhizhen Chen, Zi Cai
In this study, we reveal nontrivial quantum physics in an infinite-temperature system. By performing an unbiased quantum Monte Carlo simulation, we study a hybrid model composed of…

Identification of gapless phases by a twisting operator
Hang Su, Tengzhou Zhang, Yuan Yao +1
We propose a general necessary condition for a spin chain with SO(3) spin-rotation symmetry to be gapped. Specifically, we prove that the ground state(s) of an SO(3)-symmetric gapp…

Quantum slush state in Rydberg atom arrays
Tengzhou Zhang, Zi Cai
In this study, we propose an exotic quantum state which does not order at zero temperature in a Rydberg atom array with antiblockade mechanism. By performing an unbiased large-scal…
