Quantum Resonator as a Directional Quantum Emitter
Advanced Quantum Technologies, EarlyView.A single‐photon source based on a two‐photon Jaynes–Cummings system features a resonator acting as the quantum emitter rather than the two‐level system. In this configuration, enhanced efficiency, purity, and indistinguishability are achieved, while robustness against dephasing, reduced energy dissipation, and broader implementation prospects for ...

Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride
Rare Metals, EarlyView.ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

Unify the Effect of Anharmonicity in Double-Wells and Anharmonic Oscillators
International Journal of Theoretical PhysicsWe study the effect of anharmonicity in quantum anharmonic oscillators, by computing the energy gap between the ground and the 1st excited state using the numerical bootstrap method. Based on perturbative formulae of limiting coupling regimes, we propose a qualitative formula of the energy gap across all coupling values.

Rare Metals, EarlyView.ABSTRACT CsPbI3 quantum dots (QDs) have attracted considerable attention as promising candidates for light‐emitting diode (LED) applications. However, their intrinsic tendency to undergo a spontaneous phase transition to a nonperovskite structure significantly hampers their practical deployment. Considerable efforts have been devoted to stabilizing the

Rare Metals, EarlyView.ABSTRACT Polycrystalline SnSe thin film materials have gained increasing attention as a promising solution for fabricating microscale, flexible, self‐powered electronic components in the field of thermoelectric (TE) materials and devices. However, it is still a great challenge to simultaneously achieve preferred crystal orientation and optimize carrier

Small, EarlyView.Cross‐sectional electron microscopy reveals that antimonene hexagons exhibited inner defects and protective organic functionalization against oxidation. Temperature and power‐dependent Raman spectroscopy on varying thicknesses of FLA hexagons show that thinner flakes (<20 nm) exhibited a blueshift and intensity decrease, contrasting with the redshift ...

Small Methods, EarlyView.Selenium plays hard to get ‐ volatile, low radiative efficiency, and highly sensitive to processing. Using a closed‐space encapsulation strategy, we probe room‐temperature photoluminescence and quantify structural disorder, showing how precise structural control can turn selenium into a high‐performance optoelectronic material of tomorrow.
