This paper demonstrates a robust method for tailoring band structures in graphene superlattices using the charge density waves of 1T-NbSe, revealing that the resulting spontaneous symmetry breaking in K-folded systems arises from a structural instability rather than electronic effects.
This paper demonstrates that embedding a double-ended tuning fork resonator within a one-dimensional phononic crystal and utilizing electrostatic transduction enables the realization of high-quality mechanical oscillators, where the in-phase flexural mode confined within the bandgap exhibits a two-fold quality factor enhancement compared to an anchored resonator.
This paper predicts a superballistic radiative heat transport regime in dilute chains of plasmonic nanoparticles confined within cavities, where cavity-guided modes amplify long-range interactions to achieve a superlinear scaling of thermal conductivity that surpasses the traditional ballistic limit.
This paper identifies a uniform altermagnetic pseudogap phase in doped Mott insulators through expansion analysis, positioning it between antiferromagnetism and -wave superconductivity while suggesting its instability may lead to spin-charge liquids and quantum ordered states.
This paper proposes a novel scheme using cascaded Josephson-photonics devices to achieve highly efficient, near-projective stroboscopic detection of itinerant microwave single photons with low dark counts, potentially reaching near-unity efficiency through photon multiplication.
This paper demonstrates that while Andreev reflection in a superconducting analogue of a black hole horizon initially causes decoherence in a normal metal interferometer, increasing the coupling strength restores coherence through resonant tunneling, suggesting a novel gravitational analogue where virtual Hawking radiation enables the reemergence of quantum coherence near an event horizon.
Using the Floquet-Green function method within the Keldysh formalism, this study demonstrates that a time-periodic scalar potential applied to a Rashba spin-orbit system can induce a structurally rich, oscillating magnetization density through Fermi surface spin polarization, even in the absence of an external magnetic field.
This paper introduces complex Wannier centers derived from nonunitary Wilson loops in non-Hermitian systems to explain directional drift in Wannier functions, establishes symmetry-protected bulk-boundary correspondences linking these centers to filling anomalies and edge mode gain/loss, and proposes a photonic waveguide implementation for experimental verification.
This paper introduces a robust discrete formulation for computing the three-dimensional winding number of smooth maps to using -gaps, offering both a practical unmodified flux for fine grids and a modified flux that strictly guarantees integer quantization even in the presence of degeneracies.
This paper provides a geometric interpretation of the Schrieffer--Wolff transformation as a local coordinate chart near degeneracy submanifolds in Hermitian matrix space, establishing a "distance theorem" that links eigenvalue standard deviation to the distance from degeneracy and applying these insights to the protection of Weyl points and the geometry of degeneracy submanifolds.
