Eigenstate thermalization for observables that break Hamiltonian symmetries and its counterpart in interacting integrable systems
Tyler LeBlond, Marcos Rigol
We study the off-diagonal matrix elements of observables that break the translational symmetry of a spin-chain Hamiltonian, and as such connect energy eigenstates from different to…

Eigenstate Thermalization in a Locally Perturbed Integrable System
Marlon Brenes, Tyler LeBlond, John Goold +1
Eigenstate thermalization is widely accepted as the mechanism behind thermalization in generic isolated quantum systems. Using the example of a single magnetic defect embedded in t…

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/…
