This paper presents a comprehensive topological phase diagram for a two-dimensional electron gas in a magnetic field proximitized by a superconducting vortex lattice, revealing that Landau-level mixing and weak pairing induce a complex sequence of topological superconducting phases with varying Chern numbers and chiral edge modes.
This paper introduces an efficient classical framework that combines the fast Walsh-Hadamard transform with exact Pauli operator partitioning and Monte Carlo estimation to compute stabilizer Rényi entropies and nullity, reducing the sampling cost per Pauli string from exponential to linear complexity and enabling the study of quantum magic in highly entangled states.
This paper demonstrates that altermagnets intrinsically support highly nonlinear spin and charge pumping with giant momentum-dependent spin splitting, enabling the emission of hundreds of harmonics under realistic conditions without requiring spin-orbit coupling, thus identifying them as promising platforms for efficient THz emitters and nonlinear spintronic devices.
This paper introduces "rotonic plasmons," a new class of collective excitations in semiconductor plasmonic crystals with parabolic dispersion, and demonstrates that their gate-voltage-driven parametric resonance enables efficient, high-power RF-to-THz frequency conversion for compact 6G applications.
This paper proposes a combinatorial framework that derives fusion rules for both Abelian and non-Abelian anyonic quasiparticles in fractional quantum Hall systems directly from microscopic wave function data by extending Schrieffer's counting argument to the pattern of dominant orbital occupations.
This paper proposes a method to isolate and detect nonequilibrium Cooper quartets in a double-quantum-dot system by demonstrating that high-bias voltage driving induces a resonant two-Cooper-pair exchange process, which yields distinctive transport signatures such as a bias-dependent Andreev current peak and equal auto- and cross-correlations.
This paper develops a rigorous framework for analyzing wave propagation in 2D honeycomb structures with irrational line defects by exploiting quasiperiodicity to construct approximate edge states via a 3D embedding and a resolvent expansion, revealing that such non-commensurate geometries support infinitely many edge states with energies dense in the bulk spectral gap.
This study characterizes the angular dependence of spin-orbit coupling in SiMOS and Si/SiGe quantum dots, revealing that while both systems exhibit similar magnetic field orientations for minimizing spin-valley coupling, SiMOS devices display an order of magnitude stronger coupling than Si/SiGe, providing critical insights for optimizing silicon spin qubit performance.
This study reports the first observation of charge-density waves in genuinely isolated single and double NbS chains using the carbon-nanotube-sheath method, revealing a distinct CDW in single chains and a coexisting dimer structure with CDW in double chains, thereby challenging previous findings derived solely from quasi-one-dimensional bulk crystals.
This study combines angle-resolved photoemission spectroscopy and first-principles calculations to reveal that the topological phases of atomically thin WTe2 films evolve non-monotonically with layer thickness, oscillating between topological insulating and metallic states due to interlayer coupling-induced band reconfiguration.
