This study identifies MnTe2 as a model cubic noncollinear altermagnet by demonstrating a large piezomagnetic response through combined dilatometry and nuclear magnetic resonance measurements, which reveal a linear coupling between lattice strain and magnetic moment consistent with theoretical predictions.
This review presents a unified two-step method of symmetry breaking and restoration to describe universal strongly correlated phenomena, such as electron crystallization and rotating molecules, across diverse finite systems including quantum dots, ultracold Bose gases, and traditional nuclear and chemical fields.
This paper demonstrates that two-dimensional Floquet topological phases exhibit unexpected robustness against timing noise, characterized by a distinct two-stage decay of edge modes involving initial thermalization followed by slow algebraic decay driven by one-dimensional diffusion, thereby confirming their viability for experimental applications despite unavoidable disorder and decoherence.
This paper demonstrates that the Chebyshev expansion method can be effectively extended to non-Hermitian systems with unbounded spectra by identifying numerical rounding errors as the primary limitation and providing an analytic error bound to guide the selection of spectral radius and time steps for accurate simulations, as illustrated by the Hatano-Nelson model.
This paper resolves conflicting experimental results on spontaneous Raman scattering under vibrational strong coupling by demonstrating that the observed Raman response is governed by spatial mode overlap, which suppresses polaritonic peaks in homogeneously filled cavities but allows them in quasi-two-dimensional molecular layers.
This paper demonstrates a gate-tunable "harmonic parity qubit" that combines aluminum-oxide junctions with an InAs/Al nanowire to suppress odd Josephson harmonics and achieve controlled even-parity Cooper pair tunneling, enabling a double-well potential for advanced Fourier engineering in superconducting circuits.
This paper reports systematic resistance measurements in rhombohedral pentalayer graphene/hBN moiré superlattices that reveal displacement field-driven quantum phase transitions between various electronic states, characterized by semi-circle relations in resistivity and the discovery of a new fractional quantized anomalous Hall insulator phase.
This theoretical study demonstrates that in Marcus molecular junctions, Coulomb interactions between electrons can counterbalance the effects of thermalized phonon-induced reorganization, leading to significant qualitative changes in zero-bias conductance, Seebeck coefficient, and power factor.
This paper establishes a general framework for identifying twist and strain configurations in moiré heterostructures by analyzing moiré images, demonstrating that while wavelength data alone yields multiple possibilities, incorporating constraints like minimum elastic energy and electronic spectra allows for the determination of the most likely physical configuration.
This paper reviews Stiefel-Whitney invariants and introduces a discrete formulation of a new invariant for two-dimensional spinful insulators with twofold rotation and time-reversal symmetries, demonstrating its mathematical consistency and showing that it, alongside existing invariants, completes the stable classification .
