Charge of a quasiparticle in a superconductor

Charge of a quasiparticle in a superconductor

Significance The charge of the quasiparticles in superconductors was never, to our knowledge, directly measured. Here, we used our experience and sensitive techniques in measuring the fractional excitations in the fractional quantum Hall effect via quantum shot noise, to measure the tunneling quasiparticles in a 1D superconductor–insulator–superconductor Josephson junction, and …
