High-temperature Anyon Superconductivity
The screening of an applied magnetic field in a charged anyon fluid at finite density (μ 6= 0) and temperature (T 6= 0) is investigated. For densities typical of high-temperature superconducting materials we find that the anyon fluid exhibits a superconducting behavior at any temperature. The total Meissner screening is characterized by two penetration lengths corresponding to two short-range e...
متن کاملNon-Abelian anyon superconductivity.
Non-Abelian anyons exist in certain spin models and may exist in quantum Hall systems at certain filling fractions. In this work, we studied the ground state of dynamical SU(2) level-kappa Chern-Simons non-Abelian anyons at finite density and no external magnetic field. We find that, in the large-kappa limit, the topological interaction induces a pairing instability and the ground state is a su...
متن کاملSuperconductivity in Anyon Fluid at Finite Temperature and Density∗
The boundary effects in the screening of an applied magnetic field in a charged anyon fluid at finite density (μ 6= 0) and temperature (T 6= 0) are investigated. By analytically solving the extremum equations of the system and minimizing the free energy density, we find that in a sample with only one boundary (the half plane), a total Meissner effect takes place; while the sample with two bound...
متن کاملBosonic Chern–simons Field Theory of Anyon Superconductivity
We study the Quantum Field Theory of nonrelativistic bosons coupled to a Chern–Simons gauge field at nonzero particle density. This field theory is relevant to the study of anyon superconductors in which the anyons are described as bosons with a statistical interaction. We show that it is possible to find a mean field solution to the equations of motion for this system which has some of the fea...
متن کاملType II superconductivity and magnetic flux transport in neutron stars
The transition to a type II proton superconductor which is believed to occur in a cooling neutron star is accompanied by changes in the equation of hydrostatic equilibrium and by the formation of proton vortices with quantized magnetic flux. Analysis of the electron Boltzmann equation for this system and of the proton supercurrent distribution formed at the transition leads to the derivation of...
