This paper proposes a honeycomb lattice model of collinear altermagnets that hosts Weyl and nodal-line magnons without Dzyaloshinskii-Moriya interaction, characterized by chirality and topological invariants, which give rise to observable phenomena such as the magnon spin Nernst effect and a topology-induced differential gyromagnetic ratio detectable via the Einstein-de Haas effect.
This paper proposes bicircular Raman spectroscopy as a universal optical probe to identify altermagnetic magnons by detecting their momentum-dependent chirality and enhanced nonlinear light-magnon interactions, thereby distinguishing altermagnets from antiferromagnets regardless of the underlying magnon topology.
This paper proposes a novel route to topological superconductivity in altermagnetic topological insulators proximitized by s-wave superconductors, where altermagnetism-induced anisotropic Bogoliubov Fermi surfaces enable the realization and tunable transition of Majorana zero modes via quantum confinement and vortex engineering.
This paper proposes that vacuum fluctuations of electromagnetic fields induce a repulsive force between a superconducting circuit and an insulator, as well as an attractive force on capacitor plates proportional to the material's quantum weight, thereby offering a direct experimental method to probe the many-body quantum geometry of solids.
This study investigates the magnon properties of the metallic altermagnet , revealing that its unique symmetry induces characteristic directional splittings and anisotropic damping in spin excitations, while spin-orbit coupling opens a room-temperature-stable magnon gap.
This paper proposes a symmetry-enforced third-order nonlinear thermal Hall effect driven by Berry curvature in altermagnets, demonstrating that materials with out-of-plane Néel order (such as KV2Se2O and MnF2) exhibit a dominant third-order response with -periodic dependence, providing a novel diagnostic tool for identifying altermagnetism and determining Néel vector orientation.
This study demonstrates that while a vortex-core Majorana wave packet maintains a high retained norm when projected onto the low-energy subspace of a finite superconducting disk, its coupling to a chiral edge induces nonmonotonic spectral reorganization that leads to diverse dynamical behaviors—including rapid dephasing and sign-changing oscillations—thereby showing that a large retained norm does not guarantee spectral concentration or persistent fermion-parity memory.
This paper investigates heat transfer in a dense gas between parallel plates using the Enskog equation with a modified Enskog factor that satisfies the H-theorem, finding that while the modification has a limited impact on density, temperature, and heat flow, it produces noticeable differences in the stress tensor under severe parameter conditions.
This study demonstrates that high-quality twisted bilayer graphene grown via chemical vapor deposition (CVD) and assembled using a grow-and-stack protocol exhibits flat electronic bands comparable to those in exfoliated samples, confirming the viability of CVD for realizing magic-angle correlated states.
This paper proposes a rank-selective optical tomography method using finite photon momentum to uniquely identify the spatial rank of higher-wave altermagnetic order, demonstrating through first-principles calculations that this technique can isolate the dominant -wave component in MnTe despite symmetry-breaking effects.
