Critical velocity of a clean one-dimensional superconductor
Tzu-Chieh Wei, Paul M. Goldbart
We revisit the problem of the critical velocity of a clean one-dimensional superconductor. {\changed At the level of mean-field theory}, we find that the zero-temperature value of…
Emergence of -period oscillations in the critical temperature of small superconducting rings threaded by magnetic flux
Tzu-Chieh Wei, Paul M. Goldbart
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 cyli…
Local superfluid densities probed via current-induced superconducting phase gradients
David S. Hopkins, David Pekker, Tzu-Chieh Wei +2
We have developed a superconducting phase gradiometer consisting of two parallel DNA-templated nanowires connecting two thin-film leads. We have ramped the cross current flowing pe…
Magnetic field enhancement of superconductivity in ultra-narrow wires
A. Rogachev, T. -C. Wei, D. Pekker +3
We study the effect of an applied magnetic field on sub-10nm wide MoGe and Nb superconducting wires. We find that magnetic fields can enhance the critical supercurrent at low tempe…
