Entanglement and matrix elements of observables in interacting integrable systems
Tyler LeBlond, Krishnanand Mallayya, Lev Vidmar +1
We study the bipartite von Neumann entanglement entropy and matrix elements of local operators in the eigenstates of an interacting integrable Hamiltonian (the paradigmatic spin-1/…

Heating Rates in Periodically Driven Strongly Interacting Quantum Many-Body Systems
Krishnanand Mallayya, Marcos Rigol
We study heating rates in strongly interacting quantum lattice systems in the thermodynamic limit. Using a numerical linked cluster expansion, we calculate the energy as a function…

Prethermalization and Thermalization in Isolated Quantum Systems
Krishnanand Mallayya, Marcos Rigol, Wojciech De Roeck
Prethermalization has been extensively studied in systems close to integrability. We propose a more general, yet conceptually simpler, setup for this phenomenon. We consider a---po…
