Theoretical Design of a Bionic Spatial 3D-Arrayed Multifocal Metalens

open access: yesBiomimetics, 2022
With the development of micro/nano-optics, metasurfaces are gaining increasing attention working as novel electromagnetic wave control devices. Among which, metalenses have been developed and applied as a typical application of metasurfaces owing to ...

Geometric phase for timelike spherical normal magnetic charged particles optical ferromagnetic model

open access: yesJournal of Taibah University for Science, 2020
We introduce the theory of optical spherical Heisenberg ferromagnetic spin of timelike spherical normal magnetic flows of particles by the spherical frame in de Sitter space.

Template-based geometric simulation of flexible frameworks [PDF]

open access: yes, 2012
Specialised modelling and simulation methods implementing simplified physical models are valuable generators of insight. Template-based geometric simulation is a specialised method for modelling flexible framework structures made up of rigid units.

Simulation of quantum shortcuts to adiabaticity by classical oscillators

open access: yesFrontiers 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 polarimetry

open access: yes, 2020
This paper describes polarimetric strategies based on measuring the light's geometric phase, which results from the evolution of the polarisation state while traversing an optical system. The system in question is described by a homogeneous Jones matrix,

Geometric Phase in Phasing of Antenna Arrays [PDF]

open access: yesSymposium - International Astronomical Union, 2002
The response of a pair of differently polarized antennas is determined by their polarization states and a phase between them which has a geometric part which becomes discontinuous at singular points in the parameter space. Some consequences are described.

On the Geometric Phase and Majorana Neutrinos [PDF]

open access: yes, 2022
We analyze the geometric phase for neutrinos and we demonstrate that the geometric invariants associated with transitions between different neutrino flavors, for Majorana neutrinos, are not left unchanged by rephasing transformations and are sensitive to

Quantum Quantifiers for an Atom System Interacting with a Quantum Field Based on Pseudoharmonic Oscillator States

open access: yesEntropy, 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 ...
