Dissipation-Induced Order: The Quantum Spin Chain Coupled to an Ohmic Bath
Manuel Weber, David J. Luitz, Fakher F. Assaad
We consider an antiferromagnetic quantum Heisenberg chain where each site is coupled to an independent bosonic bath with ohmic dissipation. The coupling to the bath preserv…
Real-time evolution of static electron-phonon models in time-dependent electric fields
Manuel Weber, James K. Freericks
We present an exact Monte Carlo method to simulate the nonequilibrium dynamics of electron-phonon models in the adiabatic limit of zero phonon frequency. The classical nature of th…
Quantum Monte Carlo simulation of spin-boson models using wormhole updates
Manuel Weber
We present an exact quantum Monte Carlo method for spin systems coupled to dissipative bosonic baths which makes use of nonlocal wormhole updates to simulate the retarded spin-flip…
Electronic Mechanism that Quenches Field-Driven Heating as Illustrated with the Static Holstein Model
Manuel Weber, James K. Freericks
Time-dependent driving of quantum systems has emerged as a powerful tool to engineer exotic phases far from thermal equilibrium, but in the presence of many-body interactions it al…
Valence-Bond Order in a Honeycomb Antiferromagnet Coupled to Quantum Phonons
Manuel Weber
We use exact quantum Monte Carlo simulations to demonstrate that the Néel ground state of an antiferromagnetic SU(2) spin- Heisenberg model on the honeycomb lattice ca…
Competing Orders and Unconventional Criticality in the Su-Schrieffer-Heeger Model
Manuel Weber, Francesco Parisen Toldin, Martin Hohenadler
The phase diagram of the one-dimensional Su-Schrieffer-Heeger model of spinless fermions coupled to quantum phonons is determined by quantum Monte Carlo simulations. It differs sig…
