Low- and high-frequency noise from coherent two-level systems
Alexander Shnirman, Gerd Schön, Ivar Martin +1
Recent experiments indicate a connection between the low- and high-frequency noise affecting superconducting quantum systems. We explore the possibilities that both noises can be p…
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…
Cavity QED in superconducting circuits: susceptibility at elevated temperatures
Ileana Rau, Göran Johansson, Alexander Shnirman
We study the properties of superconducting electrical circuits, realizing cavity QED. In particular we explore the limit of strong coupling, low dissipation, and elevated temperatu…
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…
Dephasing of qubits by transverse low-frequency noise
Yuriy Makhlin, Alexander Shnirman
We analyze the dissipative dynamics of a two-level quantum system subject to low-frequency, e.g. 1/f noise, motivated by recent experiments with superconducting quantum circuits. W…
Renormalization of resonant tunneling in MOSFETs
D. Mozyrsky, I. Martin, A. Shnirman +1
We study tunneling between a localized defect state and a conduction band in the presence of strong electron-electron and electron-phonons interactions. We derive the tunneling rat…
