Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6] [PDF]
, 2009 We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.

Algebraic solutions to the dynamics of dissipative many-body quantum systems [PDF]
, 2022 From the motion of hurricanes to the cooling of a cup of tea, dissipative dynamics are ubiquitous in nature. Unfortunately, when studying lattice-based strongly correlated quantum systems, a common focus of experiments and highly relevant for material ...

Parametrically driving a quantum oscillator into exceptionality
Scientific Reports, 2023 The mathematical objects employed in physical theories do not always behave well. Einstein’s theory of space and time allows for spacetime singularities and Van Hove singularities arise in condensed matter physics, while intensity, phase and polarization

Robust Measurements of n-Point Correlation Functions of Driven-Dissipative Quantum Systems on a Digital Quantum Computer. [PDF]
Physical Review Letters, 2022 We propose and demonstrate a unified hierarchical method to measure n-point correlation functions that can be applied to driven, dissipative, or otherwise open or nonequilibrium quantum systems.

A simple tensor network algorithm for two-dimensional steady states
Nature Communications, 2017 Our understanding of open quantum many-body systems is limited because it is difficult to perform a theoretical treatment of both quantum and dissipative effects in large systems.

A random unitary circuit model for black hole evaporation
Journal of High Energy Physics, 2020 Inspired by the Hayden-Preskill protocol for black hole evaporation, we consider the dynamics of a quantum many-body qudit system coupled to an external environment, where the time evolution is driven by the continuous limit of certain 2-local random ...

Dissipative Quantum Feedback in Measurements Using a Parametrically Coupled Microcavity
PRX Quantum, 2022 Micro- and nanoscale optical or microwave cavities are used in a wide range of classical applications and quantum science experiments, ranging from precision measurements, laser technologies to quantum control of mechanical motion. The dissipative photon

Entanglement and dephasing of quantum dissipative systems [PDF]
, 2005 The von Neumann entropy of various quantum dissipative models is calculated in order to discuss the entanglement properties of these systems. First, integrable quantum dissipative models are discussed, i.e., the quantum Brownian motion and the quantum ...

Fast quantum control in dissipative systems using dissipationless solutions [PDF]
Scientific Reports, 2018 We report on a systematic geometric procedure, built up on solutions designed in the absence of dissipation, to mitigate the effects of dissipation in the control of open quantum systems. Our method addresses a standard class of open quantum systems that

Quantum Lyapunov exponent in dissipative systems
Physical Review E, 2023 The out-of-time order correlator (OTOC) has been widely studied in closed quantum systems. However, there are very few studies for open systems and they are mainly focused on isolating the effects of scrambling from those of decoherence. Adopting a different point of view, we study the interplay between these two processes. This proves crucial in order
