Topological pair-density-wave superconducting states.
We show that the pair-density-wave (PDW) superconducting state emergent in extended Heisenberg-Hubbard models in two-leg ladders is topological in the presence of an Ising spin symmetry and supports a Majorana zero mode (MZM) at an open boundary and at a junction with a uniform d-wave one-dimensional superconductor. Similarly to a conventional finite-momentum paired state, the order parameter o...
متن کاملEvolution of the local superconducting density of states in ErRh4B4 close to the ferromagnetic transition.
We present local tunneling spectroscopy experiments in the superconducting and ferromagnetic phases of the reentrant superconductor ErRh4B4. The tunneling conductance curves jump from showing normal to superconducting features within a few mK close to the ferromagnetic transition temperature, with a clear hysteretic behavior. Within the ferromagnetic phase, we do not detect any superconducting ...
متن کاملImpurity-induced local magnetism and density of states in the superconducting state of YBa2Cu3O7.
17O NMR is used to probe the local influence of nonmagnetic Zn and magnetic Ni impurities in the superconducting state of optimally doped high TC YBa2Cu3O7. Zn and Ni induce a staggered paramagnetic polarization, similar to that evidenced above TC, with a typical extension xi=3 cell units for Zn and xi>or=3 for Ni. In addition, Zn is observed to induce a local density of states near the Fermi e...
متن کاملLocal quasiparticle density of states of superconducting SmFeAsO(1-x)F(x) single crystals: evidence for spin-mediated pairing.
We probe the local quasiparticles density of states in micron-sized SmFeAsO(1-x)F(x) single crystals by means of scanning tunnelling spectroscopy. Spectral features resemble those of cuprates, particularly a dip-hump-like structure developed at energies larger than the gap that can be ascribed to the coupling of quasiparticles to a collective mode, quite likely a resonant spin mode. The energy ...
متن کاملLocal and Global Continuity of the Integrated Density of States
The integrated density of states (IDS) N(E) is the distribution function of a nonnegative measure ν, the density of states measure (DOS). This measure usually obtained as the weak infinite-volume limit of the local eigenvalue counting function for the system restricted to a finite-volume region. For Schrödinger operators with random potentials, the eigenvalue counting function for the finite-vo...
