Far-from-equilibrium scaling of non-abelian Goldstone modes
Carl Philipp Zelle, Gustav John, Orla Supple +2
We identify a broad class of nonthermal phases generated by the interplay of continuous symmetry breaking and weak nonequilibrium driving. Extending Kardar-Parisi-Zhang (KPZ) physi…
Observation of Kardar-Parisi-Zhang universal scaling in two dimensions
Simon Widmann, Siddhartha Dam, Johannes Düreth +10
Equilibrium and nonequilibrium states of matter can exhibit fundamentally different behavior. A key example is the Kardar-Parisi-Zhang universality class in two spatial dimensions…
Nonequilibrium orders in parametrically driven field theories
Carl Philipp Zelle, Romain Daviet, Andrew J. Millis +1
Driving quantum materials with coherent light has proven a powerful platform to realize a plethora of interesting phases and transitions, ranging from ferroelectricity to supercond…
Kardar-Parisi-Zhang scaling in time-crystalline matter
Romain Daviet, Carl Philipp Zelle, Armin Asadollahi +1
We discuss the universal behavior linked to the Goldstone mode associated with the spontaneous breaking of time-translation symmetry in many-body systems, in which the order parame…
Resilience of the quantum critical line in the Schmid transition
Nicolas Paris, Luca Giacomelli, Romain Daviet +3
Schmid predicted that a single Josephson junction coupled to a resistive environment undergoes a quantum phase transition to an insulating phase when the shunt resistance excee…
Nonequilibrium Criticality at the Onset of Time-Crystalline Order
Romain Daviet, Carl Philipp Zelle, Achim Rosch +1
We explore the phase transitions at the onset of time-crystalline order in models driven out-of-equilibrium. The spontaneous breaking of time translation symmetry and its Go…
On the nature of the Schmid transition in a resistively shunted Josephson junction
Romain Daviet, Nicolas Dupuis
We study the phase diagram of a resistively shunted Josephson junction (RSJJ) in the framework of the boundary sine-Gordon model. Using the non-perturbative functional renormalizat…
Universal phenomenology at critical exceptional points of nonequilibrium models
Carl Philipp Zelle, Romain Daviet, Achim Rosch +1
In thermal equilibrium the dynamics of phase transitions is largely controlled by fluctuation-dissipation relations: On the one hand, friction suppresses fluctuations, while on the…
Flowing bosonization in the nonperturbative functional renormalization-group approach
Romain Daviet, Nicolas Dupuis
Bosonization allows one to describe the low-energy physics of one-dimensional quantum fluids within a bosonic effective field theory formulated in terms of two fields: the "density…
Physical properties of the massive Schwinger model from the nonperturbative functional renormalization group
Patrick Jentsch, Romain Daviet, Nicolas Dupuis +1
We investigate the massive Schwinger model in dimensions using bosonization and the nonperturbative functional renormalization group. In agreement with previous studies we…
Chaos in the Bose-glass phase of a one-dimensional disordered Bose fluid
Romain Daviet, Nicolas Dupuis
We show that the Bose-glass phase of a one-dimensional disordered Bose fluid exhibits a chaotic behavior, i.e., an extreme sensitivity to external parameters. Using bosonization, t…
Mott-glass phase of a one-dimensional quantum fluid with long-range interactions
Romain Daviet, Nicolas Dupuis
We investigate the ground-state properties of quantum particles interacting via a long-range repulsive potential () or ${\cal V}_σ(x)\sim -|x|…
Bose-glass phase of a one-dimensional disordered Bose fluid: metastable states, quantum tunneling and droplets
Nicolas Dupuis, Romain Daviet
We study a one-dimensional disordered Bose fluid using bosonization, the replica method and a nonperturbative functional renormalization-group approach. We find that the Bose-glass…
Nonperturbative functional renormalization-group approach to the sine-Gordon model and the Lukyanov-Zamolodchikov conjecture
R. Daviet, N. Dupuis
We study the quantum sine-Gordon model within a nonperturbative functional renormalization-group approach (FRG). This approach is benchmarked by comparing our findings for the soli…
