Spin-Resolved Electronic and Transport Properties of Graphyne-Based Nanojunctions with Different N-Substituting Positions

Nanoscale Research Letters, 2019
Since the rapid development of theoretical progress on the two-dimensional graphyne nanoribbons and nanojunctions, here we investigate the electronic band structures and transport properties for the junctions based on armchair-edged γ-graphyne ...

Parametrized protocol achieving the Heisenberg limit in the optical domain via dispersive atom–light interactions

Results in Physics, 2021
The strong and collective atom–light interactions in cavity-QED systems perform manifold benefits in quantum-enhanced measurements. Here, we study the time-reversal protocol that has been proposed to sense small displacements of the light field, and ...

Auger Recombination in Semiconductor Quantum Wells [PDF]

, 1998
The principal mechanisms of Auger recombination of nonequilibrium carriers in semiconductor heterostructures with quantum wells are investigated. It is shown for the first time that there exist three fundamentally different Auger recombination mechanisms

Chip-Scale Fabry-Pérot Resonators for Blue Wavelength Photonics

IEEE Photonics Journal
Fabry-Pérot (FP) resonators are essential components for spectral control in integrated photonics. While silicon nitride (${\mathrm{Si}}_{3}{\mathrm{N}}_{4}$) is a well-established platform for visible-light applications due to its wide bandgap ...

Confidence polytopes for quantum process tomography

New Journal of Physics, 2021
In the present work, we propose a generalization of the confidence polytopes approach for quantum state tomography (QST) to the case of quantum process tomography (QPT).

Simulating Finite-Time Isothermal Processes with Superconducting Quantum Circuits

Entropy, 2021
Finite-time isothermal processes are ubiquitous in quantum-heat-engine cycles, yet complicated due to the coexistence of the changing Hamiltonian and the interaction with the thermal bath.

Quantum Stochastic Processes: A Case Study [PDF]

, 2011
We present a detailed study of a simple quantum stochastic process, the quantum phase space Brownian motion, which we obtain as the Markovian limit of a simple model of open quantum system.

Quantum model for supercontinuum generation process

Scientific Reports, 2022
A quantum theory is established for the propagation of electromagnetic waves in highly nonlinear dispersive optical fibers. By applying the method recently presented dispersion terms and retarded response of the medium are included for the propagation of
