Incoherent polarized light in treatment of purulent wounds in pigs [PDF]

open access: yesНауковий вісник ветеринарної медицини, 2020
The treatment of wounds in surgery is one of the important problems that must be solved taking into account animal species, its general condition, the stage of the wound process, and also the type of wound.

Some topics in dynamics and control of open quantum systems

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
This work reviews several topics in the non-equilibrium dynamics and control of open quantum systems, including the dynamics in the weak coupling and low density regimes, incoherent control and universal Kraus maps.

Deterministic controlled enhancement of local quantum coherence

open access: yesScientific Reports, 2022
We investigate assisted enhancement of quantum coherence in a bipartite setting with control and target systems, which converts the coherence of the control qubit into the enhanced coherence of the target qubit.

Krotov Type Optimization of Coherent and Incoherent Controls for Open Two-Qubit Systems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
This work considers two-qubit open quantum systems driven by coherent and incoherent controls. Incoherent control induces time-dependent decoherence rates via time-dependent spectral density of the environment which is used as a resource for controlling ...

Fully differentiable optimization protocols for non-equilibrium steady states

open access: yesNew Journal of Physics, 2021
In the case of quantum systems interacting with multiple environments, the time-evolution of the reduced density matrix is described by the Liouvillian.

Vacancy control in acene blends links exothermic singlet fission to coherence

open access: yesNature Communications, 2021
A complete understanding of singlet fission (SF) in molecular materials will enable the design of optimised optoelectronic devices. Here, the authors use vacancy control in acene-based blends to link coherent and incoherent SF pathways to energetics.

Controllable linear $\pi$-phase modulation in a thermal atom vapor without diffraction or absorption [PDF]

open access: yes, 2014
A scheme is proposed to achieve substantial controllable phase modulation for a probe field propagating through a thermal atomic vapor in double-$\Lambda$ configuration.

Quantum control theory and applications: A survey [PDF]

open access: yes, 2010
This paper presents a survey on quantum control theory and applications from a control systems perspective. Some of the basic concepts and main developments (including open-loop control and closed-loop control) in quantum control theory are reviewed.

A Tweezer for Chimeras in Small Networks [PDF]

open access: yes, 2015
We propose a control scheme which can stabilize and fix the position of chimera states in small networks. Chimeras consist of coexisting domains of spatially coherent and incoherent dynamics in systems of nonlocally coupled identical oscillators. Chimera

Stochastic feedback control of quantum transport to realize a dynamical ensemble of two nonorthogonal pure states [PDF]

open access: yes, 2015
A Markovian open quantum system which relaxes to a unique steady state $\rho_{ss}$ of finite rank can be decomposed into a finite physically realizable ensemble (PRE) of pure states. That is, as shown by Karasik and Wiseman [Phys. Rev. Lett. 106, 020406 (
