Influence of Fermi Surface Geometry and Van Hove Singularities on the Optical Response of SrRuO
Meghdad Yazdani-Hamid, Mehdi Biderang, Alireza Akbari
Motivated by the sensitivity of SrRuO to Fermi surface reconstructions under strain, we investigate how Fermi surface geometry and Van Hove singularities influence the opti…
Stacking of charge-density waves in 2H-NbSe bilayers
Fabrizio Cossu, Dhani Nafday, Krisztian Palotás +4
We employ ab-initio electronic structure calculations to investigate the charge-density waves and periodic lattice distortions in bilayer 2H-NbSe. We demonstrate that the verti…
Unprecedentedly large gap in HgBaCaCuO with the highest at ambient pressure
Chuanhao Wen, Zhiyong Hou, Alireza Akbari +6
In cuprate superconductors, the highest is possessed by the HgBaCaCuO (Hg-1223) system at ambient pressure, but the reason remains elusive. Here we report…
Entangled Photon Generation through Cooper Pair Recombination in a Noncentrosymmetric Quantum Well
Mehdi Biderang, Erfan Hosseini, Alireza Akbari
We explore theoretically the generation of entangled two-photon pairs by Cooper pair recombination in a noncentrosymmetric [001]-quantum well superconductor, driven by a forward-bi…
Polar Kerr Effect in Multiband Spin-Orbit Coupled Superconductors
Meghdad Yazdani-Hamid, Mehdi Biderang, Alireza Akbari
We undertake a theoretical analysis to probe the Kerr spectrum within the superconducting phase of strontium ruthenate, where the Kerr rotation experiments demonstrate the existenc…
Microscopic Insights into London Penetration Depth: Application to CeCoIn
Mehdi Biderang, Jeehoon Kim, Reza Molavi +1
We propose a comprehensive theoretical formulation of magnetic penetration depth, , based on the microscopic calculations for a general superconducting gap symmetry. Our find…
