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 ...

Acoustic geometric-phase meta-array [PDF]
New Journal of Physics, 2021 Metasurfaces based on geometric phase acquired from the conversion of the optical spin states provide a robust control over the wavefront of light, and have been widely employed for construction of various types of functional metasurface devices. However,

Topological Properties of the 2D 2-Band System with Generalized W-Shaped Band Inversion
Quantum Reports, 2022 We report the topological properties, in terms of the Berry phase, of the 2D noninteracting system with electron–hole band inversion, described by the two-band generalized analogue of the low-energy Bernevig–Hughes–Zhang Hamiltonian, yielding the W ...

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 ...

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

Gravity and geometric phases [PDF]
Physical Review D, 1995 The behavior of a quantum test particle satisfying the Klein-Gordon equation in a certain class of 4 dimensional stationary space-times is examined. In a space-time of a spinning cosmic string, the wave function of a particle in a box is shown to acquire a geometric phase when the box is transported around a closed path surrounding the string.

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.
