DOI: 10.1073/pnas.2210235119
Abstract: Significance We report that an unconventional superconducting state is formed at high pressure in UAu2. The high critical field required to suppress superconductivity and its unusual anisotropy suggest that the superconductivity has multiple components. A… read more here.

DOI: 10.1088/1361-6382/aac8a0
Abstract: We study the stability under linear odd-parity perturbations of static spherically symmetric black holes in Horndeski gravity. We derive the master equation for these perturbations and obtain the conditions of no-ghost and Laplacian instability. In… read more here.

DOI: 10.1088/1475-7516/2023/05/059
Abstract: The Einstein-Æther theory has drawn a lot of attentions in recent years. As a representative case of gravitational theories that break the Lorentz symmetry, it plays an important role in testing the Lorentz-violating effects and… read more here.

Abstract: We propose a physical scheme for the realization of two-dimensional topological odd-parity superfluidity in a spin-independent bond-centered square optical lattice based upon interband fermion pairing. The ${D}_{4}$ point-group symmetry of the lattice protects a quadratic… read more here.
