    Dependence of quasiparticle scattering length of Andreev reflection from a vortex line to the relevant parameters in polarized superfluid Fermi gas with normal-superfluid phase separation

    We consider a mass-asymmetric ultracold polarized Fermi gas accompanied by the occurrence of normal-superfluid phase separation. By considering Andreev reflection of the thermal excitations or quasiparticles f...

    Bipartite entanglement and quantum correlation and phase transition in quantum wires under Tomonaga-Luttinger liquid: spinon and holon modes analysis

    We investigate quantum correlation of quantum wires under Tomonaga-Luttinger Liquid (TLL) model via examining concurrence and quantum discord at zero temperature in terms of the coupling parameters, the veloci...

    Quantum Entanglement and Correlation Lengths of a S-wave Superconductors in the Presence of a Weak Constant External Potential

    By considering a s-wave Bardeen-Cooper-Schrieffer superconductor, as a many body system, subject to a weak constant external potential, U, using perturbed linearized Gorkov equations at zero temperature and calcu...

    Temperature Dependence of Interacting Dynamic Spin Susceptibility for Hole-Doped Cuprates in Quasi Two-Dimensional d-Wave Superconductors

    We calculate the interacting dynamic spin susceptibility of hole-doped cuprates in d-wave superconducting state based on spin-fermion model at zero and finite temperatures. The first-order approximation of the...

    Phase transition of a heavy-fermion superconductor in a high magnetic field: Entanglement analysis

    When the magnetic field is only acting on the spin of electrons, a transition from a normal to a modulated superconducting state or Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting state may occur at lo...

    Application of Boltzmann Equation on Spin Diffusion of Ferromagnetic Superfluid 3He: Near Critical Temperature

    Different scattering processes of quasiparticles containing a binary process, a coalescence process and a decay process in transition probabilities are taken into account. In the meantime, interaction between ...
