Superconducting proximity in three dimensional Dirac materials: odd-frequency, pseudoscalar, pseudovector and tensor-valued superconducting orders
Zahra Faraei, S. A. Jafari
We find that a conventional s-wave superconductor in proximity to three dimensional Dirac material (3DDM), to all orders of perturbation in tunneling, induces a combination of s an…
Sea of Majorana fermions from pseudo-scalar superconducting order in three dimensional Dirac materials
Morteza Salehi, S. A. Jafari
We find that singlet superconducting pairing can lead to Majorana fermions in three dimensional Dirac superconductors (3DDS) if the pairing order parameter is a pseudo-scalar, i.e.…
Quantitative measure for the spin-charge separation in two dimensional Hubbard model
Amir Youssefi, M. Ansari-Fard, S. A. Jafari
We introduce a qauantitative measure of spin-charge separation, which is based on the difference between the fluctuations with respect to background of the spin and charge p…
Semiconductor of spinons: from Ising band insulator to orthogonal band insulator
Tohid Farajollahpour, S. A. Jafari
Within the ionic Hubbard model, electron correlations transmute the single-particle gap of a band insulator into a Mott gap in the strong correlation limit. However understanding t…
