Microcanonical and resource-theoretic derivations of the thermal state of a quantum system with noncommuting charges [PDF]
Nature Communications, 2015 The grand canonical ensemble lies at the core of quantum and classical statistical mechanics. A small system thermalizes to this ensemble while exchanging heat and particles with a bath.

npj Computational Materials, 2022 Two-dimensional (2D) magnets have broad application prospects in the spintronics, but how to effectively control them with a small electric field is still an issue.

Time-Resolved Observation of Thermalization in an Isolated Quantum System. [PDF]
Physical Review Letters, 2015 We use trapped atomic ions forming a hybrid Coulomb crystal and exploit its phonons to study an isolated quantum system composed of a single spin coupled to an engineered bosonic environment.

Landauer's Principle in Multipartite Open Quantum System Dynamics. [PDF]
Physical Review Letters, 2015 We investigate the link between information and thermodynamics embodied by Landauer's principle in the open dynamics of a multipartite quantum system.

Synthetic quantum systems [PDF]
Smart Materials and Structures, 2002 So far proposed quantum computers use fragile and environmentally sensitive natural quantum systems. Here we explore the new notion that synthetic quantum systems suitable for quantum computation may be fabricated from smart nanostructures using topological excitations of a stochastic neural-type network that can mimic natural quantum systems.

A note on isomorphisms of quantum systems
Extracta Mathematicae, 2022 We consider the question as to whether a quantum system is uniquely determined by all values of all its observables. For this, we consider linearly nuclear GB*-algebras over W*-algebras as models of quantum systems.

Impact of blanket material and configuration on the size of a tokamak fusion reactor
Nuclear Materials and Energy, 2021 On the basis of the Korean fusion roadmap, conceptual design of the DEMO and R&D on the breeding blanket are ongoing. This article addresses the impact of blanket material and configuration on the tritium breeding, shielding characteristics, and ...

Aspects of integrability in a classical model for non-interacting fermionic fields [PDF]
, 2015 In this work we investigate the issue of integrability in a classical model for noninteracting fermionic fields. This model is constructed via classical-quantum correspondence obtained from the semiclassical treatment of the quantum system.

Full distribution of work done on a quantum system for arbitrary initial states. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2015 We propose an approach to define and measure the statistics of work, internal energy and dissipated heat in a driven quantum system. In our framework the presence of a physical detector arises naturally and work and its statistics can be investigated in ...
