Pseudomagnetic Control of Light Waves in the Electrically Tunable Photonic Crystals with Deformation Engineering

Laser &Photonics Reviews, EarlyView.
This work presents a triaxially deformed photonic crystal cavity on the SOI substrate, enabling the localization and resonating of photons via pseudomagnetic fields. Through coupling with Si waveguides and leveraging the thermo‐optic effect, electrically tunable pseudo‐magnetism‐induced optical resonances can be achieved in the photonic integrated ...

Interplay Between Spin‐Triplet Pairing and Ferromagnetism in Uranium Ditelluride

Nano Select, EarlyView.
This study investigates how spin triplet superconductivity and ferromagnetism interact in uranium ditelluride (UTe2). It shows that magnetic fluctuations strongly influence the superconducting behavior. The results suggest that ferromagnetic tendencies can contribute to the stabilization of spin triplet pairing. These findings provide new insights into

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

Natural Sciences, EarlyView.
We demonstrate laser cooling and trapping of cadmium atoms using deep‐ultraviolet light at 229 nm, capturing more than 1×107$1\times10^{7}$ atoms within 10 ms from a compact 5 cm Zeeman slower and cryogenic beam source. We achieve peak densities of 2.5×1011cm−3$2.5\times10^{11} \,\text{cm}^{-3}$ and phase‐space densities of 2×10−9$2\times10^{-9}$.

DC‐Driven Fractional Flux Quanta in Two‐Band Superconductors

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The dc‐driven distancing of fractional flux quanta is theoretically analyzed for a dual‐band superconductor with a periodic pinning potential. The analysis is based on the dynamical equation of motion for a single composite vortex. The model neglects the phase difference between the condensates and may be applicable to two‐band superconductors with ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

The minimal simple composite Higgs model

Journal of High Energy Physics, 2019
Most of the analysis of composite Higgs have focussed on the Minimal Composite Higgs Model, based on the coset SO(5) × U(1) X / SO(4) × U(1) X . We consider a model based on the coset of simple groups SO(7)/ SO(6), with SO(4) × U(1) X embedded into SO(6).

Cuprate Twistronics for Quantum Hardware

Advanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

The Smearing of Quasi‐Particles: Signatures in the Entanglement Entropy of Excited Many‐Particle Systems

Advanced Quantum Technologies, EarlyView.
Entanglement reveals hidden structure in quantum matter. We explore how quasi‐particles shape the crossover from area‐law to volume‐law entanglement, using models from spinless fermions to SYK. Our results show a striking linear growth of entanglement with energy, explained as a hallmark of quasi‐particles, offering new insight into the entanglement ...
