Decoherence in qubits due to low-frequency noise
J Bergli, Y M Galperin, B L Altshuler
The efficiency of the future devices for quantum information processing is limited mostly by the finite decoherence rates of the qubits. Recently a substantial progress was achieve…
Slow Relaxation and Equilibrium Dynamics in a 2 D Coulomb Glass: Demonstration of Stretched Exponential Energy Correlations
M. Kirkengen, J. Bergli
We have simulated energy relaxation and equilibrium dynamics in Coulomb Glasses using the random energy lattice model. We show that in a temperature range where the Coulomb Gap is…
Nonlinearly driven Landau-Zener transition with telegraph noise
J. I. Vestgarden, J. Bergli, Y. M. Galperin
We study Landau-Zener like dynamics of a qubit influenced by transverse random telegraph noise. The telegraph noise is characterized by its coupling strength, and switching rat…
Direct generation of charge carriers in c-Si solar cells due to embedded nanoparticles
Martin Kirkengen, Joakim Bergli, Yuri M. Galperin
It is known that silicon is an indirect band gap material, reducing its efficiency in photovoltaic applications. Using surface plasmons in metallic nanoparticles embedded in a sola…
Heat capacity of a thin membrane at very low temperature
O. V. Fefelov, J Bergli, Y M Galperin
We calculate the dependence of heat capacity of a free standing thin membrane on its thickness and temperature. A remarkable fact is that for a given temperature there exists a min…
Non-Gaussian dephasing in flux qubits due to 1/f-noise
Y. M. Galperin, B. L. Altshuler, J. Bergli +2
Recent experiments by F. Yoshihara et al. [Phys. Rev. Lett. 97, 167001 (2006)] and by K. Kakuyanagi et al. (cond-mat/0609564) provided information on decoherence of the echo signal…
