This paper experimentally demonstrates coherent perfect absorption of anti-modes in an indirectly coupled magnon-polariton system, revealing that the effective decay rate governs spectral amplitude while enabling magnetically tunable, frequency-selective microwave absorption.
This paper introduces and theoretically validates "persistent altermagnetic spin polarization" (PASP), a robust, mirror-symmetry-protected collinear spin texture in altermagnetic materials that persists despite spin-orbit coupling and enables switchable, high-efficiency spin-filtering for next-generation all-altermagnetic memory and transistor devices.
By combining mechanical strain with ultrafast laser pulses and x-ray scattering, researchers discovered a hidden polar phase in quantum paraelectric SrTiO3 characterized by nanoscale polarization modulations rather than conventional homogeneous ferroelectricity, offering a new explanation for its unique behavior and highlighting the importance of probing collective excitations at finite momentum.
This paper proposes that measuring quantum inductance in Majorana nanowires provides a critical, phase-sensitive probe to distinguish genuine topological fermion-parity switches from disorder-induced mimics, thereby offering a robust method to confirm the existence of Majorana zero modes when combined with quantum capacitance measurements.
This study resolves conflicting reports on the anomalous Hall effect in MnTe thin films by demonstrating that surface states, rather than the bulk, dominate the effect and that their sign can be engineered through interface design and crystal termination.
This study utilizes a frustrated cellular automata model to investigate how system size, aspect ratio, and impurity concentration influence the real-time dynamics of emergent magnetic monopoles and Dirac strings in finite artificial kagome spin ice arrays at room temperature.
This theoretical study reveals that magnetic reversion in hexagonal artificial spin ice systems proceeds via two distinct mechanisms characterized by either stationary "heavy" monopoles without Dirac chains or mobile "light" monopoles that generate extensive Dirac chains, depending on the system's energy barriers, magnetic moments, and disorder.
Using first-principles calculations and time-dependent Schrödinger equation simulations, this study demonstrates that a linear array of triangular graphane nanoclusters can efficiently transmit binary signals with near-unity efficiency under clock operations.
This paper introduces hyperbolic shear metasurfaces as ultrathin engineered surfaces that overcome the limitations of natural bulk materials by enabling geometry-controlled, ultra-confined, and low-loss hyperbolic surface waves with tailored dispersion and broadband Purcell enhancements across a wide electromagnetic spectrum.
First-principles rt-TDDFT calculations on monolayer GeS reveal that Coulomb scattering generates ballistic photocurrents comparable to shift currents, identifying a previously overlooked mechanism for the bulk photovoltaic effect.
