This paper demonstrates that incorporating effective gain and loss into twisted bilayer graphene via a non-Hermitian framework significantly enhances plasmonic performance by leveraging moiré-band reconstruction and biorthogonal matrix elements to achieve strong subwavelength confinement and extended propagation lengths, while also addressing practical limitations such as disorder and gain saturation.
This paper presents a theoretical framework demonstrating that three-dimensional exciton-polaritons in inverse-opal photonic crystals can achieve Bose-Einstein condensation with tunable critical temperatures and distinct equilibrium or nonequilibrium regimes, governed by the interplay between W-point band minima, X-point van-Hove singularities, and driven-dissipative relaxation pathways.
This paper demonstrates that conveyor-mode electron shuttling can achieve high-fidelity coherent single- and two-qubit control through electric-dipole spin resonance and diabatic gates, establishing a new architectural paradigm for reconfigurable, transport-driven semiconductor quantum processors.
This paper establishes a hybrid quantum thermodynamic uncertainty relation for normal-superconducting conductors by demonstrating that, despite complex interference between quasiparticle and Andreev processes, the nonequilibrium excess noise admits a positive representation that preserves a universal dissipation-precision constraint across arbitrary superconducting gaps.
This paper demonstrates that quantum capacitance measurements using an auxiliary quantum dot can simultaneously determine the ground-state energy splitting and Majorana bound state overlap in topological qubits, establishing QC as a powerful tool for assessing device quality and optimizing topological devices while preserving fermion parity.
This paper demonstrates that an integer quantum Hall system proximized by superconductors can exhibit a significant linear-response Seebeck effect mediated by Andreev processes, provided that both triplet superconducting correlations and spin polarization are present.
This paper demonstrates that the first negative moment of optical conductivity serves as an experimental probe for quantum geometry in phosphorus-doped silicon, revealing that a quantum geometric length characterizing donor wavefunctions jumps discontinuously to infinity at the 3D metal-insulator transition, thereby providing a quantum mechanical foundation for the Herzfeld metallization criterion and explaining the diverging dielectric response.
This paper proposes and evaluates a variational Z topological order wavefunction for fractional quantum spin Hall insulators, formed by coupling conjugate Moore-Read states via an anyonic exciton condensate, and demonstrates through Monte Carlo simulations that this state is energetically favorable over competing phases in a significant parameter space.
By combining linearly polarized ARPES and STM-based quasiparticle interference mapping with selective atomic scattering, this study characterizes the hidden ferroaxial charge density wave in LaTe as a mixed - inter-orbital order that breaks vertical mirror symmetries, thereby establishing a robust spectroscopic pathway for identifying complex electronic orders in quantum materials.
This paper proposes that intrinsic sliding ferroelectricity in bilayer 1T'-WTe can reversibly tune and significantly enhance both conventional and anomalous spin Hall conductivities, offering a promising strategy for achieving field-free magnetization switching in nonvolatile spintronic devices.
