Through Hartree-Fock calculations incorporating long-range Coulomb interactions and symmetry breaking, this study reveals that adjusting the displacement field and carrier density in Bernal bilayer graphene induces isospin-polarized metallic phases separated by full, three-quarter, half, and quarter Wigner crystal states that track the Van-Hove singularities.
This study utilizes real-time fluorescence imaging of deformed 3D trapped-ion clusters to characterize octupolar structural transitions, revealing distinct dynamical signatures such as Higgs-like mode softening, hysteresis, and stochastic switching that establish these systems as versatile platforms for investigating symmetry-breaking and complex reaction kinetics.
This paper investigates a spinful, time-reversal symmetric flatband model at filling fraction , revealing a rich phase diagram that includes a fractional topological insulator, phase separation, a spin-polarized fractional quantum Hall state, and a partially particle-hole transformed Halperin (111) state, with the specific phase determined by the parity of short-range Haldane pseudopotentials.
This paper theoretically demonstrates how strong attractive impurities can bind multiple Laughlin quasihole anyons in a fractional quantum Hall state, proposing experimental detection methods and identifying twisted MoTe as a promising platform to observe this phenomenon due to its potential for realizing the necessary strong-impurity regime.
This paper investigates the relationship between exceptional points in non-Hermitian Hamiltonians and a novel "multi-block" structure in no-jump Liouvillian superoperators, demonstrating how quantum jump terms modify this structure and affect population dynamics in open quantum systems like qubits and qutrits.
This paper introduces and validates a path-integral Monte Carlo estimator for calculating the dipole polarizability of interacting Coulomb plasma in the optical limit by utilizing collective and one-particle dipole autocorrelation functions in imaginary time, demonstrating perfect agreement with analytical Drude model references.
This paper demonstrates that perfect crystals, after undergoing mechanically driven elastic instability that transforms their atomic structure to a quasi-amorphous state, exhibit quasi-brittle plastic yielding characterized by power-law dislocation avalanches indicative of self-induced marginal stability, similar to well-annealed glassy materials.
This paper theoretically demonstrates that interfacial Dzyaloshinskii-Moriya interaction in a two-dimensional d-wave altermagnet induces phonon-chirality-selective magnon-phonon hybridization, creating magnon polarons with a d-wave phonon angular momentum texture that enables a bosonic analogue of the spin-splitter effect known as the phonon angular momentum splitter.
This comment refutes a recent claim that the polaromechanical normal-mode splitting observed in a 2025 study is invalid, arguing that the splitting is indeed present in a narrow frequency range and that the critics' reliance on total decay rates defined by spectral poles is irrelevant to the effective decay rate vanishing under coherent perfect absorption conditions.
This paper proposes a two-qubit spectroscopy method using tailored pulse sequences to independently extract environmental response and noise, enabling the resolution of spatio-temporal correlation spreading, light-cone dynamics, and distinct transport regimes in quantum many-body systems.
