This paper investigates disorder-induced entanglement phase transitions in non-Hermitian Hatano-Nelson models, revealing that weak disorder transforms the area-law entanglement scaling into a logarithmic regime before a critical disorder strength triggers a transition back to area-law behavior with universal algebraic scaling at the critical point.
By introducing spin-orbit coupling via substrate proximity in rhombohedral trilayer graphene, researchers demonstrated a tripling of the superconducting critical temperature driven by a quantitative change in spin-canting angles rather than a change in ground state symmetry, suggesting that fluctuations in this magnetic order facilitate the pairing interaction.
This paper investigates how the geometry of a bilayer graphene quantum ripple and orbital angular momentum influence electronic states, modeled by a spinless electron constrained to the surface via the Da Costa potential.
This paper presents a comprehensive theoretical study using exact diagonalization to demonstrate that finite graphene strips with short zigzag edges, when proximitized by an s-wave superconductor and subjected to Rashba spin-orbit coupling and Zeeman fields, provide a robust platform for topologically protected Majorana zero modes that can be reliably distinguished from trivial Andreev bound states even in the presence of disorder.
This paper demonstrates that while Liouvillian exceptional points in a collective spin system induce super-Lorentzian spectral features, these signatures are suppressed in steady-state fluorescence but become clearly observable in the emission spectra of generic initial states, offering a viable spectroscopic diagnostic for many-body non-Hermitian phases.
This study establishes that robust half-quantized thermal conductance in chiral topological Josephson junctions serves as a reliable signature of single chiral Majorana modes, provided specific conditions regarding low doping, junction length, and phase difference are met, while non-local electrical conductance remains suppressed.
This paper establishes the exact localization phase diagram of the Hofstadter model on a hexagonal lattice with irrational magnetic flux by applying Avila's global theory to a two-by-two transfer matrix, revealing three distinct phases (extended, localized, and critical) without mobility edges, a finding subsequently validated by renormalization group theory and numerical fractal dimension analysis.
Using variational Monte Carlo with neural quantum states and projected entangled pair states, this study investigates the triangular-lattice Hofstadter-Hubbard model to directly observe spin-charge separation and demonstrate the efficacy of these computational methods in diagnosing topological order and fractionalized excitations in strongly correlated systems.
This paper demonstrates that long-range hoppings in non-Hermitian coupled chains fundamentally reorganize the competition between skin accumulation and hybridization, replacing the conventional logarithmic critical-length law with a new hierarchy of algebraic and scale-covariant scaling regimes driven by nonlocal mechanisms.
This paper establishes a unified framework based on double antisymmetry group theory to classify linear time-invariant photonic systems into twelve distinct symmetry categories, thereby systematically defining how compound symmetries involving reciprocity, energy conservation, and time reversal constrain electromagnetic responses and thermal radiation.
