Nonperturbative treatment of a quenched Langevin field theory
Friederike Ihssen, Valerio Pagni, Jamir Marino +2
We present a novel approach within the functional renormalization group framework for computing critical exponents that characterize the time evolution of out-of-equilibrium many-b…
Quantum wires with local particle loss: Transport manifestations of fluctuation-induced effects
Marcel Gievers, Thomas Müller, Heinrich Fröml +2
We investigate the transport properties of a quantum wire of weakly interacting fermions in the presence of local particle loss. We calculate current and conductance in this system…
Orthogonality catastrophe in dissipative quantum many body systems
F. Tonielli, R. Fazio, S. Diehl +1
We present an analog of the phenomenon of orthogonality catastrophe in quantum many body systems subject to a local dissipative impurity. We show that the fidelity , giving a…
Lattice duality for the compact Kardar-Parisi-Zhang equation
L. M. Sieberer, G. Wachtel, E. Altman +1
A comprehensive theory of the Kosterlitz-Thouless transition in two-dimensional superfluids in thermal equilibrium can be developed within a dual representation which maps vortices…
Electrodynamic duality and vortex unbinding in driven-dissipative condensates
G. Wachtel, L. M. Sieberer, S. Diehl +1
We investigate the superfluid properties of two-dimensional driven Bose liquids, such as polariton condensates, using their long-wavelength description in terms of a compact Kardar…
Thermodynamic Equilibrium as a Symmetry of the Schwinger-Keldysh Action
L. M. Sieberer, A. Chiocchetta, A. Gambassi +2
The time evolution of an extended quantum system can be theoretically described in terms of the Schwinger-Keldysh functional integral formalism, whose action conveniently encodes t…
Non-equilibrium Functional Renormalization for Driven-Dissipative Bose-Einstein Condensation
L. M. Sieberer, S. D. Huber, E. Altman +1
We present a comprehensive analysis of critical behavior in the driven-dissipative Bose condensation transition in three spatial dimensions. Starting point is a microscopic descrip…
