Geometric nature of the environment-induced Berry phase and geometric dephasing
Robert S. Whitney, Yuriy Makhlin, Alexander Shnirman +1
We investigate the geometric phase or Berry phase (BP) acquired by a spin-half which is both subject to a slowly varying magnetic field and weakly-coupled to a dissipative environm…
Dephasing due to nonstationary 1/f noise
J. Schriefl, M. Clusel, D. Carpentier +2
Motivated by recent experiments with Josephson qubits we propose a new phenomenological model for 1/f noise due to collective excitations of interacting defects in the qubit's envi…
Spin and Current Variations in Josephson Junctions
A. Shnirman, Z. Nussinov, Jian-Xin Zhu +2
We study the dynamics of a single spin embedded in the tunneling barrier between two superconductors. As a consequence of pair correlations in the superconducting state, the spin d…
