Steady-state coherences under partial collective non-Markovian decoherence
Physical Review ResearchSteady-state coherence in open quantum systems is crucial for quantum technologies, yet its behavior is not fully understood due to the interplay between collective and individual decoherence.

SciPost Physics CoreOpen quantum many-body systems exhibit nontrivial behavior under decoherence. In particular, system-environmental entanglement (SEE) is one of the efficient quantities for classifying mixed states subject to decoherence.

A proposed test of quantum dissipation theory using Kapitza–Dirac electron diffraction
New Journal of Physics, 2022 Decoherence can be provided by a dissipative environment as described by the Caldeira–Leggett equation. This equation is foundational to the theory of quantum dissipation.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Decoherence and Ontology [PDF]
, 2019 This paper discusses the consequences of quantum mechanics for our understanding of physical reality, particularly regarding how classical concepts emerge from quantum laws; how common sense logic stands out as a special case of quantum logic applied to macroscopic objects; how causality and locality are found to be “provincial” consequences of quanta;

Phase‐Dependent Oxygen Defect Energetics in Epitaxial NbN/AlN/NbN Films
Advanced Science, EarlyView.Phase dependent oxygen defect energetics in epitaxial δ‐NbN/AlN/δ‐NbN and β‐Nb2N/AlN/β‐Nb2N trilayers. Atomic‐scale analysis and first‐principles calculations reveal distinct oxygen incorporation pathways across NbN polymorphs. Layer resolved defect formation energies show that O is energetically more favorable within δ‐NbN electrodes, whereas in β ...

Decoherence without dissipation [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 That decoherence can take place in the presence of energy conservation seems to be a poorly known fact. That lack of knowledge has, for example, bedevilled the discussion of the ‘black hole information’ problem. I present a simple model that illustrates such energy-free decoherence.

Quantum‐Like Dynamics in Whole‐Brain Models of the Human Connectome
Advanced Science, EarlyView.Quantum‐like dynamics in the human brain. The level of quantum‐like behavior in a non‐quantum system of coupled oscillators is regulated by the spectral gap of the coupling graph. Whole‐brain modelling using QL fits the empirical data significantly better and has a lower model‐derived energy cost than the non‐QL model.
