Dissipation-induced Liouville-Majorana modes in open quantum system
Physical Review Research, 2023 In open quantum systems, topological edge states rapidly lose coherence, making them unsuitable for topological quantum computation and quantum memory.

Operator growth in open quantum systems: lessons from the dissipative SYK [PDF]
Journal of High Energy Physics, 2022 We study the operator growth in open quantum systems with dephasing dissipation terms, extending the Krylov complexity formalism of [ 1 ]. Our results are based on the study of the dissipative q -body Sachdev-Ye-Kitaev (SYK_ q ) model, governed by the ...

Operator Growth in Open Quantum Systems. [PDF]
Physical Review Letters, 2022 The spreading of quantum information in closed systems, often termed scrambling, is a hallmark of many-body quantum dynamics. In open systems, scrambling competes with noise, errors, and decoherence.

Phase transitions in the classical simulability of open quantum systems
Scientific Reports, 2023 We introduce a Langevin unravelling of the density matrix evolution of an open quantum system over matrix product states, which we term the time-dependent variational principle-Langevin equation.

Effective-Hamiltonian Theory of Open Quantum Systems at Strong Coupling [PDF]
PRX Quantum, 2022 We present the reaction-coordinate polaron-transform (RCPT) framework for generating effective Hamiltonian models to treat nonequilibrium open quantum systems at strong coupling with their surroundings.

The early universe as an open quantum system: complexity and decoherence [PDF]
Journal of High Energy PhysicsIn this work, we extend previous results, demonstrating how complexity in an open quantum system can identify decoherence between two fields, even in the presence of an accelerating background.

, 2023 In this Bachelor thesis project, the Lindblad master equation is derived, both as the most general way of modeling interaction with an environment that lacks memory, and through microscopic derivations focused on assumptions about the way the system interacts with its environment (weak-coupling, Born-Markov and rotating wave approximations). It is then

Spontaneous emission of matter waves from a tunable open quantum system [PDF]
Nature, 2017 The decay of an excited atom undergoing spontaneous photon emission into the fluctuating quantum-electrodynamic vacuum is an emblematic example of the dynamics of an open quantum system.
