Formation of Quantum Phase Slip Pairs in Superconducting Nanowires
Andrey Belkin, Maxim Belkin, Victor Vakaryuk +2
Macroscopic quantum tunneling (MQT) is a fundamental phenomenon of quantum mechanics related to the actively debated topic of quantum-to-classical transition. The ability to realiz…
Universal features of counting statistics of thermal and quantum phase slips in superconducting nanocircuits
A. Murphy, P. Weinberg, T. Aref +4
We perform measurements of phase-slip-induced switching current events on different types of superconducting weak links and systematically study statistical properties of the switc…
Phase soliton and pairing symmetry of a two-band superconductor: Role of the proximity effect
Victor Vakaryuk, Valentin Stanev, Wei-Cheng Lee +1
We suggest a mechanism which promotes the existence of a phase soliton -- topological defect formed in the relative phase of superconducting gaps of a two-band superconductor with…
Quantitative analysis of quantum phase slips in superconducting MoGe nanowires revealed by switching-current statistics
T. Aref, A. Levchenko, V. Vakaryuk +1
We measure quantum and thermal phase-slip rates using the standard deviation of the switching current in superconducting nanowires at high bias current. Our rigorous quantitative a…
Stability of topological defects in chiral superconductors: London theory
Victor Vakaryuk
This paper examines thermodynamic stability of chiral domain walls and vortices - topological defects which can exist in chiral superconductors. Using London theory it is demonstra…
Effect of half-quantum vortices on magnetoresistance of perforated superconducting films
Victor Vakaryuk, Valerii Vinokur
Recent cantilever magnetometry measurements of annular micron-size samples of Sr2RuO4 have revealed evidence for the existence of half-quantum vortices (HQVs) in this material [Jan…
