Parent Hamiltonians of Ergodic Matrix Product States

Owen Ekblad, Eloy Moreno-Nadales, Eric B. Roon +1

Matrix product states (MPS) are quintessential examples of frustration-free gapped ground states of local interactions called parent Hamiltonians. In this work, we investigate pare…

Finitely Correlated States Driven by Topological Dynamics

Eric B. Roon, Jeffrey H. Schenker

Let be a standard probability space and let be a measure preserving ergodic homeomorphism. Let be a -algebra with a unit and let…

Periodicity in Ergodic Quantum Processes

Owen Ekblad, Jeffrey Schenker

We study the periodic properties of sequences of quantum channels sampled from an ergodic stochastic process satisfying a natural irreducibility condition. We relate these periodic…

Reducibility Theory and Ergodic Theorems for Ergodic Quantum Processes

Owen Ekblad, Jeffrey Schenker

We develop a Perron-Frobenius type theory for products of random quantum channels acting on finite-dimensional matrix algebras sampled from a stationary and ergodic stochastic proc…

Disordered Ground States of Ergodic Quantum Spin Systems

Eric B. Roon, Jeffrey H. Schenker

In this letter, we fill a hole in the existing literature about disordered quantum spin systems generated by a random local interaction $\{\mathfrak{h}(Z)\}_{Z\Subset \mathbb{Z}^ν…

Asymptotic Behavior of Random Time-Inhomogeneous Markovian Quantum Dynamics

Lubashan Pathirana, Jeffrey Schenker

We study the asymptotic behavior of continuous-time, time-inhomogeneous Markovian quantum dynamics in a stationary random environment. Under mild faithfulness and eventually positi…
