Dynamics of non-Markovian open quantum systems

I De Vega, D Alonso - Reviews of Modern Physics, 2017 - APS
Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

Quantum systems under frequency modulation

MP Silveri, JA Tuorila, EV Thuneberg… - Reports on Progress …, 2017 - iopscience.iop.org
We review the physical phenomena that arise when quantum mechanical energy levels are
modulated in time. The dynamics resulting from changes in the transition frequency is a …

Testing the validity of the 'local'and 'global'GKLS master equations on an exactly solvable model

JO González, LA Correa, G Nocerino… - Open Systems & …, 2017 - World Scientific
When deriving a master equation for a multipartite weakly-interacting open quantum
systems, dissipation is often addressed locally on each component, ie ignoring the coherent …

Entangled biphoton generation in the myelin sheath

Z Liu, YC Chen, P Ao - Physical Review E, 2024 - APS
Consciousness within the brain hinges on the synchronized activities of millions of neurons,
but the mechanism responsible for orchestrating such synchronization remains elusive. In …

Quantum field theory based quantum information: Measurements and correlations

C Anastopoulos, BL Hu, K Savvidou - Annals of Physics, 2023 - Elsevier
This is the first in a series of papers aiming to develop a relativistic quantum information
theory in terms of unequal-time correlation functions in quantum field theory. In this work, we …

Disorder-enhanced transport in a chain of lossy dipoles strongly coupled to cavity photons

TF Allard, G Weick - Physical Review B, 2022 - APS
We study the interplay between disorder and light-matter coupling by considering a
disordered one-dimensional chain of lossy dipoles coupled to a multimode optical cavity …

Driven quantum dynamics: will it blend?

L Banchi, D Burgarth, MJ Kastoryano - Physical Review X, 2017 - APS
Randomness is an essential tool in many disciplines of modern sciences, such as
cryptography, black hole physics, random matrix theory, and Monte Carlo sampling. In …

Effective master equations for two accelerated qubits

G Kaplanek, E Tjoa - Physical Review A, 2023 - APS
We revisit the problem involving two constantly accelerating Unruh-DeWitt detectors using
open effective field theory methods. We study the time evolution of the joint detector state …

Quantum dynamics of molecular ensembles coupled with quantum light: Counter-rotating interactions as an essential component

YT Chuang, LY Hsu - Physical Review A, 2024 - APS
The rotating-wave approximation (discarded of counter-rotating interactions) to light-matter
interactions is widely used in the quantum electrodynamics Hamiltonian; however, its validity …

Fundamental limits to frequency estimation: a comprehensive microscopic perspective

JF Haase, A Smirne, J Kołodyński… - New Journal of …, 2018 - iopscience.iop.org
We consider a metrology scenario in which qubit-like probes are used to sense an external
field that affects their energy splitting in a linear fashion. Following the frequency estimation …
