Thermodynamics of vortex lines in layered superconductors
Roberto Iengo, Claudio A. Scrucca
We study the dissipative thermodynamics of vortex lines in layered superconductors within a simple string model in the dilute limit of negligible vortex interactions and compute th…
Supercurrent Decay by Vortex Nucleation in the Presence of an Array of Pinning Centres: A Renormalization Group Approach
Roberto Iengo, Giancarlo Jug
We study the phenomenon of decay of a supercurrent in a superconducting thin film due to the spontaneous homogeneous nucleation of quantized vortex-antivortex pairs in the absence…
Edge Tunneling of Vortices in Superconducting Thin Films
Roberto Iengo, Giancarlo Jug
We investigate the phenomenon of the decay of a supercurrent due to the zero-temperature quantum tunneling of vortices from the edge in a thin superconducting film in the absence o…
Microscopic Oscillations in the Quantum Nucleation of Vortices Subject to Periodic Pinning Potential in a Thin Superconductor
Roberto Iengo, Giancarlo Jug
We present a theory for the decay of a supercurrent through nucleation of vortex-antivortex pairs in a two-dimensional superconductor in the presence of dissipation and of a period…
Vortex Pair Production and Decay of a 2-D Supercurrent by a Quantum Field Theory Approach
Roberto Iengo, Giancarlo Jug
We investigate the phenomenon of the decay of a supercurrent through homogeneous nucleation of vortex-antivortex pairs in a 2-D like superconductor or superfluid by means of a quan…
Magnetic screening properties of an incompressible chiral fluid
Pietro Donatis, Roberto Iengo
We study the possible penetration of a static magnetic field in an idealized sample of many layers supporting a two dimensional charged chiral quantum fluid, to see whether there i…
Effective Theory of a Chiral Superfluid
Pietro Donatis, Roberto Iengo
We consider an effective Lagrangian describing a fluid living on two-di\-men\-sio\-nal planes. The fluid self-interacts through a Chern-Simons vector potential, whose field strengt…
