Enforced Gaplessness from States with Exponentially Decaying Correlations
Rahul Sahay, Curt von Keyserlingk, Ruben Verresen +1
It is well known that an exponentially localized Hamiltonian must be gapless if its ground state has algebraic correlations. We show that even certain exponentially decaying correl…

Dissipation-assisted operator evolution method for capturing hydrodynamic transport
Tibor Rakovszky, C. W. von Keyserlingk, Frank Pollmann
We introduce the dissipation-assisted operator evolution (DAOE) method for calculating transport properties of strongly interacting lattice systems in the high temperature regime.…
