Lattice models of fermions, bosons, and spins have long served to elucidate the essential physics of quantum phase transitions in a variety of systems. Generalizing such models to incorporate driving and dissipation has opened new vistas to investigate nonequilibrium phenomena and dissipative phase transitions in interacting many-body systems. We present a framework for the treatment of such open quantum lattices based on a resummation scheme for the Lindblad perturbation series. Employing a…

Driven-Dissipative Quantum Many-Body Systems
My PhD was devoted to the study of driven-dissipative quantum many-body systems. These systems represent natural platforms to explore fundamental questions about matter under non-equilibrium
Perturbative approach to weakly driven many-particle systems in the presence of approximate conservation laws
We develop a Liouville perturbation theory for weakly driven and weakly open quantum systems in situations when the unperturbed system has a number of conservations laws. If the perturbation violates
Phase diagram of the dissipative quantum Ising model on a square lattice
The competition between interactions and dissipative processes in a quantum many-body system can drive phase transitions of different order. Exploiting a combination of cluster methods and quantum
Linked cluster expansions for open quantum systems on a lattice
We propose a generalization of the linked-cluster expansions to study driven-dissipative quantum lattice models, directly accessing the thermodynamic limit of the system. Our method leads to the
Keldysh field theory for driven open quantum systems.
This work provides a systematic introduction to the open system Keldysh functional integral approach, which is the proper technical tool to accomplish a merger of quantum optics and many-body physics, and leverages the power of modern quantum field theory to driven open quantum systems.
Competing coherent and dissipative dynamics close to quantum criticality
We investigate the competition of coherent and dissipative dynamics in many-body systems at continuous quantum transitions. We consider dissipative mechanisms that can be effectively described by
Scaling behavior of the stationary states arising from dissipation at continuous quantum transitions
We study the critical behavior of the nonequilibrium dynamics and of the steady states emerging from the competition between coherent and dissipative dynamics close to quantum phase transitions. The
Thermalization in open quantum systems
We study thermalization in open quantum systems using the Lindblad formalism. A method that both thermalizes and couples to Lindblad operators only at edges of the system is introduced. Our method
Tailored jump operators for purely dissipative quantum magnetism
I propose an archtitecture for the realization of dissipative quantum many-body spin models. The dissipative processes are mediated by interactions with auxiliary particles and lead to a widely

We present analytical solutions for the mean-field master equation of the driven-dissipative Bose-Hubbard model for cavity photons, in the limit of both weak pumping and weak dissipation. Instead of
Dynamical phase transition in the open Dicke model
In well-controlled sweeps across the Hepp–Lieb–Dicke phase transition, hysteretic dynamics showing power-law scaling with respect to the transition time suggests an interpretation in terms of a Kibble–Zurek mechanism, and indicates the possibility of universal behavior in the presence of dissipation.
Quantum correlations in the one-dimensional driven dissipative XY model
We study the non-equilibrium steady state (NESS) of a driven dissipative one-dimensional system near a critical point, and explore how the quantum correlations compare to the known critical behavior
Circuit QED lattices: Towards quantum simulation with superconducting circuits
The Jaynes‐Cummings model describes the coupling between photons and a single two‐level atom in a simplified representation of light‐matter interactions. In circuit QED, this model is implemented by
Super-fermion representation of quantum kinetic equations for the electron transport problem.
This work converts the problem of finding the nonequilibrium steady state to the many-body problem with non-hermitian liouvillian in super-Fock space, introduces nonequ equilibrium quasiparticles by a set of canonical nonunitary transformations and develops general many- body theory for the electron transport through the interacting region.
Dynamics of nonequilibrium Dicke models
Motivated by experiments observing self-organization of cold atoms in optical cavities, we investigate the collective dynamics of the associated nonequilibrium Dicke model. The model displays a rich
Perturbative approach to Markovian open quantum systems
This work presents a perturbative treatment of Markovian open quantum systems which will be useful for an analytical understanding ofopen quantum systems and for numerical calculation of system observables which would otherwise be impractical.
