This paper demonstrates that -valley twisted square homobilayers offer a highly tunable platform for realizing the square-lattice Hubbard model, where an interlayer displacement field breaks emergent layer-exchange symmetry to enable wide-range experimental control over the effective hopping ratio .
This paper demonstrates that Klein tunneling in Dirac altermagnets serves as an efficient, gate-controllable mechanism to significantly enhance and switch spin-current polarization, particularly in g-wave systems where intrinsic polarization is negligible.
This paper investigates how electrostatic barriers in silicene induce tunable Goos–Hänchen shifts and group delay times in Dirac fermions through quantum interference, demonstrating that these lateral and temporal dynamics can be controlled by varying incident energy, angle, and barrier parameters.
This paper comments on a 2025 study by Fujiwara et al. that provides clear evidence of charge density wave synchronization in NbSe3 nanowires through the observation of Shapiro steps on I-V curves when driven by resonant surface acoustic waves generated on a piezoelectric substrate.
This paper demonstrates a scalable, strain-engineered approach using buried AlAs/AlO stressors to deterministically grow high-quality InGaAs/GaAs quantum dots that emit single photons in the telecom O-band without degrading optical coherence, thereby enabling site-controlled integration for long-distance quantum communication.
This paper introduces a zero-bias superconducting voltage amplifier that utilizes the bipolar thermoelectric effect and negative differential resistance in an asymmetric SIS junction to achieve a 20 dB gain and broadband frequency response up to 180 MHz solely from a thermal gradient, offering a promising solution for cryogenic signal processing and quantum instrumentation.
This paper demonstrates that a topological soliton in a one-dimensional Dirac system induces a momentum-dependent exchange coupling via its localized zero mode, creating a form factor that suppresses high-energy scattering and thereby allows the soliton's real-space structure to directly control the emergent Kondo energy scale.
This paper demonstrates that resonant driving of the middle polariton branch in coupled cavities suppresses coherent Rabi oscillations in favor of monotonic relaxation, a regime that supports interacting Bogoliubov excitations with a phonon-like dispersion arising from the hybrid nature of intercavity polaritons.
This paper introduces a generalized non-Abelian line graph theory that incorporates internal degrees of freedom and spin-orbit coupling to construct flat bands in multi-orbital systems, specifically demonstrating the realization of -orbital flat bands in Kagome lattices as a minimal model for transition metal materials.
This paper demonstrates the first in-situ tunable, room-temperature polariton condensation in individual states of a one-dimensional Su-Schrieffer-Heeger topological lattice using an open-cavity organic polymer configuration, enabling precise engineering of band structures and selective state occupation for accurate analogue simulation of quantum fluids.
