Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Quantum switch instabilities with an open control
Communications PhysicsThe superposition of causal orders shows promise in various quantum technologies. However, the fragility of quantum systems arising from environmental interactions, leading to dissipative behavior and irreversibility, demands a deeper understanding of ...

Quasi-autonomous quantum thermal machines and quantum to classical energy flow
New Journal of Physics, 2016 There are both practical and foundational motivations to consider the thermodynamics of quantum systems at small scales. Here we address the issue of autonomous quantum thermal machines that are tailored to achieve some specific thermodynamic primitive ...

arXiv, 2017 Inspired by classical ("actual") Quantum Theory over $\mathbb{C}$ and Modal Quantum Theory (MQT), which is a model of Quantum Theory over certain finite fields, we introduce General Quantum Theory as a Quantum Theory -- in the K{\o}benhavn interpretation -- over general division rings with involution, in which the inner product "is" a $(\sigma,1 ...

Theory of open quantum systems
, 2002 A quantum dissipation theory is constructed with the system–bath interaction being treated rigorously at the second-order cumulant level for both reduced dynamics and initial canonical boundary condition.

Entanglement entropy and quantum field theory [PDF]
, 2004 We carry out a systematic study of entanglement entropy in relativistic quantum field theory. This is defined as the von Neumann entropy SA = −Tr ρAlogρA corresponding to the reduced density matrix ρA of a subsystem A.

Duke Mathematical Journal, 1997 For a simple vertex operator algebra $V$ and a finite automorphism group $G$ of $V$ then $V$ is a direct sum of $V^ $ where $ $ are irreducible character of $G$ and $V^ $ is the subspace of $V$ which $G$ acts according to the character $ .$ We prove the following: 1. Each $V^ $ is nonzero. 2. $V^ $ is a tensor product $M_ \otimes V_ $ where $M_

Interpretations of quantum theory: A map of madness [PDF]
, 2015 Motivated by some recent news, a journalist asks a group of physicists: "What's the meaning of the violation of Bell's inequality?" One physicist answers: "It means that non-locality is an established fact".

Quantum theory of irreversibility [PDF]
Physica A: Statistical Mechanics and its Applications, 2007 A generalization of the Gibbs-von Neumann relative entropy is proposed based on the quantum BBGKY [Bogolyubov-Born-Green-Kirkwood-Yvon] hierarchy as the nonequilibrium entropy for an N-body system. By using a generalization of the Liouville-von Neumann equation describing the evolution of a density super- operator, it is demonstrated that the entropy ...
