This study demonstrates that controllably introducing disorder via iron cluster deposition in monolayer Fe(Te,Se) drives a superconductor-insulator transition, revealing a disorder-induced quantum phase transition characterized by the evolution from superconducting to insulating U-shaped gaps attributed to localization-enhanced Cooper pair correlations.
This study demonstrates that LaIrO is an orbital-selective spin-orbit Mott insulator where structural distortions and dimerization drive the bands to half-filling for correlation-driven Mott localization, while the bands remain band-insulating.
This paper develops a non-equilibrium bosonization framework based on the Keldysh action to analyze charge statistics, Green's functions, and tunneling transport in fractional quantum Hall edges, demonstrating how interaction-induced anyonic fractionalization and braiding phases manifest in measurable observables like the Fano factor for both single-mode and multi-mode systems.
Using the traveling-solvent floating zone technique, high-quality single crystals of the distorted triangular lattice antiferromagnet CuLaGeO were successfully grown and characterized, revealing weak magnetic frustration, a low-temperature ordering transition at 1.14 K, and a unique noncollinear antiferromagnetic structure with an ordered moment of 0.89 lying in the bc-plane.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
Using strong-coupling time-dependent perturbation theory, this paper demonstrates that higher-harmonic currents in Mott-Hubbard and charge-transfer insulators encode information about spin order and microscopic hopping pathways, establishing them as effective probes for correlated materials and sensors for driving fields.
This paper establishes that dynamical quantum phase transitions (DQPTs) in generic quadratic fermionic systems are fundamentally characterized by the restoration of spin-flip symmetry in specific zero-energy dynamical critical modes, providing a unified framework that explains the necessary but insufficient conditions for DQPTs and their relationship to ground-state quantum phase transitions.
This paper provides direct experimental evidence for the superfluid nature of composite bosons in GaAs quantum Hall systems by demonstrating a bulk Meissner-like effect, where a controlled time-varying magnetic field induces quantized charge accumulation to maintain a fixed electron-to-flux ratio, with the screening mechanism transitioning between charge-mediated and fixed-density regimes depending on the presence of a top gate.
This study demonstrates non-thermal, ultrafast optical control of ferromagnetism in the centrosymmetric material CrGeTe by utilizing a resonant nonlinear Edelstein effect to generate an effective Edelstein-Zeeman field that drives magnetization dynamics, as evidenced by polarization-dependent THz emission spectroscopy.
This paper introduces group surface codes as a generalization of the surface code that enables universal quantum computation by implementing non-Clifford gates and transversal classical operations, thereby bypassing the computational limitations of topological Pauli stabilizer models imposed by the Bravyi-König theorem.
This theoretical study investigates magnon-magnon interactions in a two-dimensional Heisenberg-Kitaev honeycomb ferromagnet with Dzyaloshinskii-Moriya interaction, revealing that the critical temperature for temperature-induced topological phase transitions monotonically approaches the Curie temperature as DMI strength increases and is correlated with both DMI and magnetic field strength.
This paper establishes a generalized -pairing framework for interacting non-Hermitian Hubbard models in arbitrary dimensions, revealing novel phenomena such as asymmetric eigenoperators, spatially modulated states, and anomalous skin effects that unify and extend traditional symmetry concepts beyond Hermitian limits.
Using sign-problem-free determinant quantum Monte Carlo simulations, this study demonstrates that introducing next-nearest-neighbor hopping in the attractive Hubbard model on a square lattice can significantly enhance the critical temperature by up to 50% while simultaneously reducing the pseudogap region, offering a viable route to achieve experimentally accessible superconducting temperatures.
This study establishes a computational framework linking the random interlayer stacking of mesoscopic 1-TaS flakes to their complex electronic properties, demonstrating that Hubbard repulsion drives a coexistence of metallic, band, and Mott insulating states that cannot be explained by ordinary band theory.
The authors develop a non-Hermitian generalization of the numerical renormalization group (NRG) method to non-perturbatively solve the non-Hermitian Kondo model, revealing a novel phase with a stable fixed point and complex eigenspectrum in the pseudogap regime while providing open-source code for further exploration.
This study reveals that while atomically thin monolayer and bilayer MnTe lose their bulk altermagnetic properties due to symmetry constraints, they instead exhibit distinct emergent magnetic phases characterized by robust layered antiferromagnetism in bilayers and unprecedented spin-glass-like behavior in monolayers.
This study experimentally demonstrates a topological magneto-optical Kerr effect in the noncoplanar antiferromagnet Co1/3TaS2 that arises from real-space scalar spin chirality without relying on spin-orbit coupling or net magnetization, thereby establishing a new mechanism for ultrafast, stray-field-immune opto-spintronic applications.
This study reports the discovery of an unprecedented time-reversal symmetry breaking superconducting state accompanied by electronic glass dynamics in epitaxially strained (La, Pr, Sm)₃Ni₂O₇ bilayer nickelate films, evidenced by unconventional magnetoresistance hysteresis, zero-field non-reciprocity, and logarithmically slow resistance relaxations.
This paper demonstrates that -paraparticles in one-dimensional Luttinger models exhibit flavor-charge separation and can be bosonized under specific conditions, offering a theoretical pathway to detect these exotic quasiparticles through distinct dispersion profiles in low-temperature systems.
This paper theoretically demonstrates that Coulomb interactions in quantum Hall ferromagnets enable long-range magnon scattering off point charges and facilitate the transduction of magnons between separate bilayer layers via skyrmions, offering a pathway for all-electrical long-range magnonics.
