Kondo nanomechanical dissipation in the driven Anderson impurity model

Lucas Kohn, Giuseppe E. Santoro, Michele Fabrizio +1

The cyclic sudden switching of a magnetic impurity from Kondo to a non-Kondo state and back was recently shown to involve an important dissipation of the order of several …

Quenching the Anderson impurity model at finite temperature: Entanglement and bath dynamics using matrix product states

Lucas Kohn, Giuseppe E. Santoro

We study the dynamics of the quenched Anderson model at finite temperature using matrix product states. Exploiting a chain mapping for the electron bath, we investigate the entangl…

Efficient mapping for Anderson impurity problems with matrix product states

Lucas Kohn, Giuseppe E. Santoro

We propose an efficient algorithm to numerically solve Anderson impurity problems using matrix product states. By introducing a modified chain mapping we obtain significantly lower…

Superfluid to Mott transition in a Bose-Hubbard ring: Persistent currents and defect formation

Lucas Kohn, Pietro Silvi, Matthias Gerster +4

We revisit here the Kibble-Zurek mechanism for superfluid bosons slowly driven across the transition towards the Mott-insulating phase. By means of a combination of the Time-Depend…

Dissipation assisted Thouless pumping in the Rice-Mele model

Luca Arceci, Lucas Kohn, Angelo Russomanno +1

We investigate the effect of dissipation from a thermal environment on topological pumping in the periodically-driven Rice-Mele model. We report that dissipation can improve the ro…

Probabilistic low-rank factorization accelerates tensor network simulations of critical quantum many-body ground states

Lucas Kohn, Ferdinand Tschirsich, Maximilian Keck +3

We provide evidence that randomized low-rank factorization is a powerful tool for the determination of the ground state properties of low-dimensional lattice Hamiltonians through t…
