An Extension of ETH to Non-Equilibrium Steady States
Sanjay Moudgalya, Trithep Devakul, D. P. Arovas +1
We extend the notion of the Eigenstate Thermalization Hypothesis (ETH) to Open Quantum Systems governed by the Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) Master Equation. We pres…
Operator Spreading in Quantum Maps
Sanjay Moudgalya, Trithep Devakul, C. W. von Keyserlingk +1
Operators in ergodic spin-chains are found to grow according to hydrodynamical equations of motion. The study of such operator spreading has aided our understanding of many-body qu…
Anderson localization transitions with and without random potentials
Trithep Devakul, David A. Huse
We explore single-particle Anderson localization due to nonrandom quasiperiodic potentials in two and three dimensions. We introduce a class of self-dual models that generalize the…
Obtaining highly excited eigenstates of the localized XX chain via DMRG-X
Trithep Devakul, Vedika Khemani, Frank Pollmann +2
We benchmark a variant of the recently introduced DMRG-X algorithm against exact results for the localized random field XX chain. We find that the eigenstates obtained via DMRG-X e…
Probability distribution of the entanglement across a cut at an infinite-randomness fixed point
Trithep Devakul, Satya N. Majumdar, David A. Huse
We calculate the probability distribution of entanglement entropy S across a cut of a finite one dimensional spin chain of length L at an infinite randomness fixed point using Fish…
Many-body localization phase transition: A simplified strong-randomness approximate renormalization group
Liangsheng Zhang, Bo Zhao, Trithep Devakul +1
We present a simplified strong-randomness renormalization group (RG) that captures some aspects of the many-body localization (MBL) phase transition in generic disordered one-dimen…
Nonzero temperature Entanglement Negativity of quantum spin models: Area law, Linked Cluster Expansions and Sudden Death
Nicholas E. Sherman, Trithep Devakul, Matthew B. Hastings +1
We show that the bipartite logarithmic entanglement negativity (EN) of quantum spin models obeys an area law at all nonzero temperatures. We develop numerical linked cluster (NLC)…
Unusual Corrections to Scaling and Convergence of Universal Renyi Properties at Quantum Critical Points
Sharmistha Sahoo, E. Miles Stoudenmire, Jean-Marie Stéphan +3
At a quantum critical point, bipartite entanglement entropies have universal quantities which are subleading to the ubiquitous area law. For Renyi entropies, these terms are known…
On the entanglement across a cubic interface in 3+1 dimensions
Trithep Devakul, Rajiv R. P. Singh
We calculate the area, edge and corner Renyi entanglement entropies in the ground state of the transverse-field Ising model, on a simple-cubic lattice, by high-field and low-field…
Quantum Critical Universality and Singular Corner Entanglement Entropy of Bilayer Heisenberg-Ising model
Trithep Devakul, Rajiv R. P. Singh
We consider a bilayer quantum spin model with anisotropic intra-layer exchange couplings. By varying the anisotropy, the quantum critical phenomena changes from XY to Heisenberg to…
