Geometric Phase in Twisted Topological Complementary Pair [PDF]

Advanced Science, 2023
Geometric phase enabled by spin‐orbit coupling has attracted enormous interest in optics over the past few decades. However, it is only applicable to circularly‐polarized light and encounters substantial challenges when applied to wave fields lacking the

Geometric Phase-Induced Stückelberg Interference in an Optical Lattice Clock [PDF]

Entropy
We theoretically investigate geometric Stückelberg interferometry in a doubly driven optical lattice clock (OLC). By tuning the relative phase between the two driving fields, we control the relative sign of the effective coupling strengths at the avoided

Geometric phase in quantum synchronization

Physical Review Research, 2023
We consider a quantum limit-cycle oscillator implemented in a spin system whose quantization axis is slowly rotated. Using a kinematic approach to define geometric phases in nonunitary evolution, we show that the quantum limit-cycle oscillator attains a ...

Control of the Geometric Phase in Two Open Qubit–Cavity Systems Linked by a Waveguide [PDF]

Entropy, 2020
We explore the geometric phase in a system of two non-interacting qubits embedded in two separated open cavities linked via an optical fiber and leaking photons to the external environment.

Spatially Multiplexing of Metasurface for Manipulating the Focused Trefoil and Cinquefoil Vector Light Field

Nanomaterials, 2021
The trefoil and cinquefoil vector field are of essential significance for fundamental topology properties as the Hopf link and trefoil knots in the light field.

Geometric phase in Taub-NUT spacetime

European Physical Journal C: Particles and Fields, 2023
Constructing the Hamiltonian in the $$\eta $$ η -representation, we explore the geometric phase in the Taub-NUT spacetime, which is spherically symmetric and stationary.

Single-Layered Phase-Change Metasurfaces Achieving Polarization- and Crystallinity-Dependent Wavefront Manipulation

Photonics, 2023
As a promising platform for versatile electromagnetic (EM) manipulations, metasurfaces have drawn wide interest in recent years due to their unique EM properties and small footprints.

Demon driven by geometric phase

Physical Review Research, 2023
We theoretically study the entropy production and the work extracted from a system connected to two reservoirs by periodic modulations of the electrochemical potentials of the reservoirs and the parameter of a system Hamiltonian under isothermal ...

Anomalous Spectral Shift of o-Modes in Multilayer Photonic Structure Induced by Homeotropic–Homeoplanar Transition in Chiral–Nematic Defect Layer

Photonics, 2023
A chiral nematic is embedded between multilayer mirrors to obtain voltage-inducible polarized resonance spectra. Initially, the nematic director is uniformly oriented perpendicular to the mirrors’ surfaces because the chiral nematic helix is completely ...
