Speed limit for open quantum systems

open access: yesNew Journal of Physics, 2019
We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time and the physical quantities such as the energy fluctuation and the entropy ...

Quantum Fokker-Planck models: an Open System Approach

open access: yes, 2011
We start with a short introduction to quantum master equations for semigroups of completely positive normal maps describing the evolution of open quantum systems and discuss in, particular, the structure of generators (Gorini-Kossakowski-Sudarshan ...

Non-Equilibrium Properties of Open Quantum Systems [PDF]

open access: yes, 2022
We study two classes of open systems: discrete-time quantum walks (a type of Floquet-engineered discrete quantum map) and the Lindblad master equation (a general framework of dissipative quantum systems), focusing on the non-equilibrium properties of ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Probing non-Markovian quantum dynamics with data-driven analysis: Beyond “black-box” machine-learning models

open access: yesPhysical Review Research, 2022
A precise understanding of the influence of a quantum system's environment on its dynamics, which is at the heart of the theory of open quantum systems, is crucial for further progress in the development of controllable large-scale quantum systems ...

Efficient flow equations for dissipative systems

open access: yesSciPost Physics, 2022
Open quantum systems provide an essential theoretical basis for the development of novel quantum technologies, since any real quantum system inevitably interacts with its environment. Lindblad master equations capture the effect of Markovian environments.

Simulating quantum Brownian motion with single trapped ions [PDF]

open access: yes, 2004
We study the open system dynamics of a harmonic oscillator coupled with an artificially engineered reservoir. We single out the reservoir and system variables governing the passage between Lindblad-type and non-Lindblad-type dynamics of the reduced ...

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Lectures on open quantum systems

open access: yesCanadian Journal of Physics
These notes are a short introduction to the mathematical theory of open quantum systems. They are meant to serve as an entry point into a broad research area that has applications across the quantum sciences dealing with systems subjected to external noise. The idea is to let the key structures of the theory emerge from a concrete model.
