Primordial black holes and scalar induced gravitational waves from sound speed resonance in non-minimal derivative coupling inflation model Open
We investigate an inflationary model with a non-minimal derivative coupling, where the coupling function contains both constant and periodic components. On large scales, the model is in excellent agreement with the latest Planck-ACT-LiteBI…

Photon Routing Induced by Giant Atoms in a Synthetic Frequency Dimension Open
We propose a hardware-efficient photon routing scheme based on a dynamically modulated multi-mode ring resonator and a driven cyclic three-level artificial atom, which effectively models a two-level giant atom coupled to a pair of one-dime…

Spectral properties and exact solutions for Rabi-coupled noninteracting fermions in a spin-dependent anharmonic trapping potential Open
We investigate the effect of spin-motion coupling on the spectral properties of Rabi-coupled noninteracting fermions in a spin-dependent harmonic trapping potential plus an anharmonic term. It is shown that when the spin-motion coupling be…

Nonlinear periodic waves and their stabilities for a Bose–Einstein condensate in a nonlinear lattice Open
We investigate a special class of nonlinear periodic waves and their stabilities for a Bose–Einstein condensate in a pure cosine nonlinear lattice. It is shown that for a specific range of the lattice parameters, we can obtain two differen…

Dynamic sensitivity of quantum Rabi model with quantum criticality Open
We study the dynamic sensitivity of the quantum Rabi model, which exhibits quantum criticality in the finite-component-system case. This dynamic sensitivity can be detected by introducing an auxiliary two-level atom far-off-resonantly coup…

All-Solid-State DUV Light Source by Quadrupling of an Acousto-Optically Q-Switched Nd:YVO<sub>4</sub> Laser Open
All-solid-state 228.5 nm Deep Ultraviolet (DUV) laser has been studied with two-step second harmonious generation (SHG) of Nd:YVO4 914 nm fundamental laser, by optimizing its resonator design and SHG configurations. Adopting three-mirror f…

Critically enhanced spin-nematic squeezing and entanglement in dipolar spinor condensates Open
We study the quantum critical effect enhanced spin-nematic squeezing and quantum Fisher information (QFI) in the spin-1 dipolar atomic Bose-Einstein condensate. We show that the quantum phase transitions can improve the squeezing and QFI i…

Confinement Effect Driven Quantum Spin Hall Effect in Monolayer AuTe<sub>2</sub>Cl Open
Based on first-principles calculations, we predict that the monolayer AuTe 2 Cl is a quantum spin Hall (QSH) insulator with a topological band gap about 10 meV. The three-dimensional (3D) AuTe 2 Cl is a topological semimetal that can be vi…

Chaos and $\mathcal{PT}$-symmetry breaking transitions in a driven, nonlinear dimer with balanced gain and loss Open
Dynamics of a simple system, such as a two-state (dimer) model, are dramatically changed in the presence of interactions and external driving, and the resultant unitary dynamics show both regular and chaotic regions. We investigate the non…
