Simulation of quantum shortcuts to adiabaticity by classical oscillators
Frontiers in Physics, 2023 It is known that the dynamics and geometric phase of a quantum system can be simulated by classical coupled oscillators using the quantum−classical mapping method without loss of physics.

Geometric Phase for degenerate states of spin-1 and spin-1/2 pair [PDF]
, 2007 The geometric phase of a bi-particle model is discussed. For different initial states, especially when the initial state is pure or mixed, the geometric phase will show different properties.

Towards detecting traces of non-contact quantum friction in the corrections of the accumulated geometric phase [PDF]
npj Quantum Information, 2019 The geometric phase can be used as a fruitful venue of investigation to infer features of the quantum systems. Its application can reach new theoretical frontiers and imply innovative and challenging experimental proposals.

Geometric phase for mixed states: a differential geometric approach [PDF]
, 2003 A new definition and interpretation of geometric phase for mixed state cyclic unitary evolution in quantum mechanics are presented. The pure state case is formulated in a framework involving three selected Principal Fibre Bundles, and the well known ...

Entropy, 2018 We develop a useful model considering an atom-field system interaction in the framework of pseudoharmonic oscillators. We examine qualitatively the different physical quantities for a two-level atom (TLA) system interacting with a quantized coherent ...

Orbital Angular Momentum Generation and Detection by Geometric-Phase Based Metasurfaces [PDF]
, 2018 We present a comprehensive review on the geometric-phase based metasurfaces for orbital angular momentum (OAM) generation and detection. These metasurfaces manipulate the electromagnetic (EM) wave by introducing abrupt phase change, which is strongly ...

Noncyclic geometric phase for neutrino oscillation [PDF]
, 2000 We provide explicit formulae for the noncyclic geometric phases or Pancharatnam phases of neutrino oscillations. Since Pancharatnam phase is a generalization of the Berry phase, our results generalize the previous findings for Berry phase in a recent ...

All-Dielectric Meta-Surface for Multispectral Photography by Theta Modulation
Nanomaterials, 2020 The traditional theta modulator encodes input information by superimposing Ronchi sub-gratings, which is extremely easy to cause spatial channel overlap that results in bands mixing.

Photonic spin Hall effect: fundamentals and emergent applications
Opto-Electronic Science, 2022 The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with opposite spin angular momentum, after the beam passes through an optical interface or inhomogeneous medium, manifested as the spin-dependent splitting. It can be
