Found 8 papers in prb We have found the first instance of a third-order topological Anderson insulator (TOTAI). This disorder-induced topological phase is gapped and characterized by a quantized octupole moment and topologically protected corner states, as revealed by a detailed numerically exact analysis. We also find t… We study charge transport in voltage-biased single-channel junctions involving helical superconductors with finite Cooper pair momentum. For a Josephson junction, the equilibrium current-phase relation shows a superconducting diode effect: the critical current depends on the propagation direction. W… We study the transport properties of a tight-binding model of noninteracting fermions with random hopping on the honeycomb lattice. At the particle-hole-symmetric chemical potential, the absence of diagonal disorder (random on-site potentials) places the system in the well-studied chiral orthogonal … Photonic bound states in the continuum (BIC) promise a versatile platform for construction of optical resonators with highly confined electromagnetic fields and ultralong radiative lifetime. Merging multiple BIC can enable suppression of out-of-plane radiative losses and further boost the quality (Q… Non-Hermitian quantum systems exhibit fascinating characteristics such as non-Hermitian topological phenomena and skin effects, yet their studies are limited by the intrinsic difficulties associated with their eigenvalue problems, especially in larger systems and higher dimensions. In Hermitian syst… The microscopic pairing mechanism for superconductivity in magic-angle twisted bilayer graphene remains an open question. Recent experimental studies seem to rule out a purely electronic mechanism due to the insensitivity of the critical superconducting temperature to either a highly doped screening… Time modulation provides an important degree of freedom for classical wave steering in topological manners. Rather than using the spatial dimension to mimic time, here we design and implement an acoustic temporal lattice with time-varying couplings to demonstrate a unique type of strongly localized … Degeneracy points in non-Hermitian systems are of great interest. While a homotopic framework exists for understanding their behavior in the absence of symmetry, it does not apply to symmetry-protected degeneracy points with reduced codimension. In this work, utilizing algebraic topology, we provide…

Found 1 papers in pr_res A first-principles formalism that enables the topological characterization of Weyl points in three-dimensional dispersive photonic continua is introduced. The chirality of Weyl points is computed through gap Chern numbers and through direct computation of the Berry curvature, in both cases solely using the photonic Green’s function.
