Size of flux jumps in superconducting films
D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +2
Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a…
Fluctuations of the Fermi condensate in ideal gases
Dragos-Victor Anghel, Oleg Fefelov, Y. M. Galperin
We calculate numerically and analytically the fluctuations of the fermionic condensate and of the number of particles above the condensate for systems of constant density of states…
1/f noise in hopping conduction: Role of multi-site aggregates
V. I. Kozub, Y. M. Galperin, V. Vinokur
We propose a mechanism for 1/f-type noise in hopping insulators based on the multi-electron charge redistribution within the specific aggregates of the localized states located in…
Charge transfer between a superconductor and a hopping insulator
V. I. Kozub, A. A. Zyuzin, Y. M. Galperin +1
We develop a theory of the low-temperature charge transfer between a superconductor and a hopping insulator. We show that the charge transfer is governed by the coherent two-electr…
Low-frequency noise as a source of dephasing of a qubit
Y. M. Galperin, B. L. Altshuler, D. V. Shantsev
With the growing efforts in isolating solid-state qubits from external decoherence sources, the material-inherent sources of noise start to play crucial role. One representative ex…
AC-Hopping Conductance of Self-Organized Ge/Si Quantum Dot Arrays
Irina L. Drichko, Andrey M. Diakonov, Veniamin I. Kozub +4
Dense ( cm) arrays of Ge quantum dots in Si host were studied using attenuation of surface acoustic waves (SAWs) propagating along the surface of a piezo…
