Experimental detection of a Majorana mode in the core of a magnetic vortex inside a topological insulator-superconductor Bi(2)Te(3)/NbSe(2) heterostructure.
TLDR
This work provides self-consistent evidences of Majorana fermions and also suggests a possible route to manipulating them by systematically investigating the spatial profile of the Majorana mode and the bound quasiparticle states within a vortex in Bi(2)Te(3) films grown on a superconductor NbSe(2).
Iron-based high transition temperature superconductors
In a superconductor electrons form pairs and electric transport becomes dissipation-less at low temperatures. Recently discovered iron-based superconductors have the highest superconducting
Self-doped Mott insulator for parent compounds of nickelate superconductors
Motivated by analyses of the reported electrical resistivity and Hall coefficient data in the normal state, the authors propose that the parent compound of the newly discovered superconducting
Impurity effect on weak antilocalization in the topological insulator Bi2Te3.
TLDR
The data demonstrate that the observed WAL is robust against deposition of nonmagnetic Au impurities on the surface of the thin films, but it is quenched by the deposition of magnetic Fe impurities which destroy the π Berry phase of the topological surface states.
Artificial Topological Superconductor by the Proximity Effect
Topological superconductors (TSCs) have a full gap in the bulk and gapless surface states consisting of Majorana fermions, which have potential applications in fault-tolerant topological quantum
A Phenomenological Theory of The Pseudogap State
An ansatz is proposed for the coherent part of the single particle Green's function in a doped resonant valence bond (RVB) state by, analogy with the form derived by Konik and coworkers for a doped
Directional ordering of fluctuations in a two-dimensional compass model.
TLDR
Transition to the disordered phase is shown to be in the Ising universality class through exact mapping and multicanonical Monte Carlo simulations.
Majorana Zero Mode Detected with Spin Selective Andreev Reflection in the Vortex of a Topological Superconductor.
Recently, theory has predicted a Majorana zero mode (MZM) to induce spin selective Andreev reflection (SSAR), a novel magnetic property which can be used to detect the MZM. Here, spin-polarized
Nature of stripes in the generalized t?J model applied to the cuprate superconductors
A recent study of the transport properties on the stripe phase in La1.875Ba01.25CuO4 by Li et al (2007 Phys. Rev. Lett. 99 067001) found two-dimensional (2D) superconductivity over a wide temperature
Particle-hole asymmetry in doped mott insulators: implications for tunneling and photoemission spectroscopies.
TLDR
It is shown that the origin of the particle-hole asymmetry lies in the incoherent spectral weight, and a novel method is proposed, based on ratios of sum rules, to estimate local density variations in inhomogeneous materials.
