Observation of a robust zero-energy bound state in iron-based superconductor Fe(Te,Se)
The symmetry of Cooper pairs in iron-based superconductors is an issue under continued investigation. A scanning tunnelling study of Fe(Te,Se) reveals a robust zero-energy bound state, providing
Theory of the phonon Hall effect in paramagnetic dielectrics.
Based upon Raman spin-lattice interaction, this theory reproduces the essential experimental features of the phonon Hall effect, including the sign, magnitude, and linear magnetic field dependence of the thermal Hall conductivity.
Pressure-induced topological quantum phase transition in Sb2Se3
Based on the first-principles band structure calculations, we investigate the effects of hydrostatic pressure on the conventional insulator (CI) Sb_2Se_3 and predict that it undergoes a topological
Ferromagnetism and superconductivity with possible p +i p pairing symmetry in partially hydrogenated graphene
By means of first-principles calculations, we predict two new types of partially hydrogenated graphene systems: C$_{6}$H$_{1}$ and C$_{6}$H$_{5}$, which are shown to be ferromagnetic (FM) semimetal
Two‐dimensional balance equations in nonlinear electronic transport and application to GaAs‐GaAlAs heterojunctions
A non‐Boltzmann theory of steady‐state transport for two‐dimensional systems in a strong electric field is developed, which includes a force‐ and an energy‐balance equation. The electron temperature,
Thermoelectric power of Dirac fermions in graphene
On the basis of self-consistent Born approximation for Dirac fermions under charged impurity scatterings in graphene, we study the thermoelectric power using the heat current-current correlation
Quasiparticle states around a nonmagnetic impurity in a d-density-wave state of high-T(c) cuprates.
The electronic structure around a single nonmagnetic impurity in the d-density-wave (DDW) ordering is studied. It is found that a single subgap resonance peak appears in the local density of states
Exploring Exotic Superfluidity of Polarized Ultracold Fermions in Optical Lattices
We explore theoretically the novel superfluidity of harmonically-trapped polarized ultracold fermionic atoms in a two-dimensional (2D) optical lattice by solving the Bogoliubov-de Gennes equations.
Mean-field description of the phase string effect in the t-J model
A mean-field treatment of the phase string effect in the $t-J$ model is presented. Such a theory is able to unite the antiferromagnetic (AF) phase at half-filling and metallic phase at finite doping
Ginzburg-Landau equations for layered p -wave superconductors
Based on Gor{close_quote}kov{close_quote}s theory of weakly coupled superconductors, the Ginzburg-Landau equations for layered p-wave superconductors are derived, the order parameter of which is
