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…

Making Trotters Sprint: A Variational Imaginary Time Ansatz for Quantum Many-body Systems
Matthew J. S. Beach, Roger G. Melko, Tarun Grover +1
We introduce a variational wavefunction for many-body ground states that involves imaginary time evolution with two different Hamiltonians in an alternating fashion with variable t…
