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-enabled unconditional strongly sub-Poissonian squeezing

Physical Review Research
It is generally accepted that the role of quantum decoherence is to spoil the quantum superpositions and to yield the emergence of the classical behaviors from quantum mechanics.

Decoherence without entanglement and quantum Darwinism

Physical Review Research, 2020
It is often assumed that decoherence arises as a result of the entangling interaction between a quantum system and its environment, as a consequence of which the environment effectively measures the system, thus washing away its quantum properties ...

Scaling behavior of electron decoherence in a graphene Mach-Zehnder interferometer

Nature Communications, 2022
Quantum Hall edge channels provide a platform to study electron interference, however understanding decoherence in these systems remains an open problem. Jo et al.

QUANTUM DECOHERENCE AND GRAVITATIONAL WAVES

Beyond the Quantum, 2007
The quite different behaviors exhibited by microscopic and macroscopic systems with respect to quantum interferences suggest the existence of a borderline beyond which quantum systems loose their coherences and can be described classically. Gravitational waves, generated within our galaxy or during the cosmic expansion, constitute a universal ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Effects of Lorentz symmetry breaking on quantum coherence in an expanding universe

Physics Letters B
This study investigates the interplay between Lorentz invariance violation (LIV) and quantum decoherence within an expanding universe. Motivated by quantum-gravity phenomenology, we incorporate a minimal length scale via spatial discretization, which ...

Classical decoherence in a nanomechanical resonator

New Journal of Physics, 2016
Decoherence is an essential mechanism that defines the boundary between classical and quantum behaviours, while imposing technological bounds for quantum devices.
