We consider the energy of the filled quasiparticle's Fermi sea of a macroscopic
superconducting ring threaded by an hc/2 e vortex, when the material of the ring is of an …

As a function of the magnetic flux threading the object, the Little-Parks oscillation in the
critical temperature of a large-radius, thin-walled superconducting ring or hollow cylinder …

Based on the finite U slave boson method, we have investigated the effect of Rashba spin-
orbit (SO) coupling on the persistent charge and spin currents in a one-dimensional …

We analyze the crossover from an hc/e periodicity of the persistent current in flux-threaded
clean metallic rings toward an hc/2 e-flux periodicity of the supercurrent upon entering the …

The notion of persistent current goes back to orbital currents in normal metals,
semiconductors and even insulators displaying diamagnetic behavior in weak magnetic …

Wave functions of low-energy quasiparticle subgap states in d-wave superconducting rings,
threaded by an Aharonov-Bohm magnetic flux, are found analytically. The respective …

We investigate a finite two-dimensional system in the presence of an external magnetic field.
We discuss how the energy spectrum depends on the system size, boundary conditions, and …

Interest in hybrid quasi-one-dimensional systems with an inner semiconducting part coated
with a superconductor (the so-called core/shell structure) has been grown in the last decade …

Quantization of the transverse electron motion in high-quality superconducting metallic
nanowires and nanofilms results in the formation of well-distinguished single-electron …

The magnetic flux dependence of order parameter and supercurrent is studied in a hollow d-
wave superconducting cylinder. It is shown that the existence of line nodal quasiparticles in …
