Detecting Topological Order at Finite Temperature Using Entanglement Negativity
Tsung-Cheng Lu, Timothy H. Hsieh, Tarun Grover
We propose a diagnostic for finite temperature topological order using `topological entanglement negativity', the long-range component of a mixed-state entanglement measure. As a d…
Entanglement Renyi negativity across a finite temperature transition: a Monte Carlo study
Kai-Hsin Wu, Tsung-Cheng Lu, Chia-Min Chung +2
Quantum entanglement is fragile to thermal fluctuations, which raises the question whether finite temperature phase transitions support long-range entanglement similar to their zer…
Structure of Quantum Entanglement at a Finite Temperature Critical Point
Tsung-Cheng Lu, Tarun Grover
We propose a scheme to characterize long-range quantum entanglement close to a finite temperature critical point using tripartite entanglement negativity. As an application, we stu…
