We propose a scheme to observe the Majorana-zero-mode-induced crossed Andreev reflection by measuring tunneling current directly. In this scheme a metallic ring structure is utilized to separate electron and hole signals. Since tunneling electrons an

The Weyl semimetal in a constant magnetic field is investigated with the ground state for the lowest ($n=0$) Landau levels corresponding to spin-down (${\ensuremath{\sigma}}_{3}=\ensuremath{-}1$). In the presence of an electron-phonon coupling in the

Recent discoveries in graphene bilayers have revealed that when one of the layers is rotated by a specific angle, superconductivity emerges. We provide an explanation for this phenomenon. We find that due to the layer rotations, the spinors are modif

One of the goals of modern spectroscopy is to invent techniques which detect neutral excitations that have been theoretically proposed. For superconductors, two-point transport measurements detect the Andreev crossed reflection which confirms the exi

The electron–electron interaction in Weyl semimetals induces a coupling between the chiral electronic bands. As a result, a sliding density wave is induced and observed by Gooth et al. (2019) Here we compute the Hall conductivity at finite temperat

We present a new theory of photoemission for Weyl semimetals. We derive this theory using a model with a boundary surface at z = 0 . Due to the boundary, the self adjoint condition needs to be verified in order to ensure physical solutions. The solut

We compute the magnetoelectric response of an interacting topological insulator in three space dimensions with a short range interaction between electrons in different orbitals. We show that in the presence of interactions and inverted bands the chir

Dirac's method for constraints is used for solving the problem of exclusion of double occupancy for Correlated Electrons. The constraints are enforced by the pair operator $Q(\vec{x})=\psi_{\downarrow}(\vec{x})\psi_{\uparrow}(\vec{x})$ which annihila

We investigate an effective one-dimensional conducting channel considering both the contact umklapp and the Coulomb electron–electron interaction. We show that, at low electronic density, the proximity to the Wigner crystal reproduces the anomaly i
