Depth Control of Room-Temperature Quantum Emitters in Gallium Nitride

This paper identifies that naturally occurring quantum emitters in gallium nitride are confined near the substrate interface, limiting their optical coupling, and demonstrates that inserting a thin low-temperature GaN interlayer enables the precise, sub-60 nm depth control of bright, room-temperature quantum emitters, thereby overcoming integration barriers for efficient cavity-enhanced quantum emission.

Magneto-optical transport in type-I multi-Weyl semimetals in the presence of orbital magnetic moment

This paper investigates the linear and nonlinear magneto-optical transport in tilted type-I multi-Weyl semimetals using a semiclassical Boltzmann framework, deriving analytical expressions that reveal how orbital magnetic moment corrections generally suppress Berry curvature-induced conductivity while offering distinct experimental signatures of the materials' anisotropic dispersion and higher monopole charges.

Electric field tunable magnetoexcitons in Xenes-hBN-TMDC, Xenes-hBN-BP, and Xenes-hBN-TMTC heterostructures

This theoretical study proposes and analyzes novel van der Waals heterostructures combining Xenes with TMDCs, phosphorene, or TMTCs separated by hBN layers, demonstrating that their Rydberg indirect excitonic properties can be effectively tuned via external electric and magnetic fields, dielectric screening, and Floquet engineering to facilitate advanced optoelectronic and quantum device design.

Layer-Dependent Interfacial Coupling and Exciton Pinning in WSe2/Graphene Heterostructures

This study demonstrates that growing WSe2 on graphene induces persistent compressive strain and layer-dependent charge transfer that pin exciton energies, contrasting with the thickness-dependent shifts observed on SiO2/Si, thereby establishing graphene as an active interface for controlling excitonic properties in scalable van der Waals heterostructures.

Chirality Driven Ratchet Currents in Two-Dimensional Tellurene with an Asymmetric Grating

This study demonstrates that two-dimensional tellurene, leveraging its inherent chiral atomic structure, generates a gate-tunable, helicity-dependent circular ratchet current at room temperature under terahertz radiation, a phenomenon successfully explained by a microscopic theory based on the Boltzmann kinetic equation.

Large scale theoretical investigation of the phase diagram of twisted bilayer MoTe2_2 at fractional fillings: agreements and contradictions with current experiments

This study employs comprehensive exact-diagonalization calculations on twisted bilayer MoTe2_2 to demonstrate that including interaction-driven band mixing in a two-band-per-valley model is essential for accurately reproducing the experimentally observed hierarchy of fractional Chern insulators and charge density wave states, while also ruling out the proposed non-abelian Pfaffian state at specific fillings.
