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…
Spin echo without an external permanent magnetic field
Joakim Bergli, Leonid Glazman
The spin echo techniques aim at the elimination of the effect of a random magnetic field on the spin evolution. These techniques conventionally utlize the application of a permanen…
Ohmic and non-Ohmic Andreev transport through an interface between superconductor and hopping insulator: Dramatic role of barrier properties
M. Kirkengen, J. Bergli, Y. M. Galperin
At low temperatures and voltages tunneling transport through an interface between a superconductor and hopping insulator is dominated by coherent two-electron tunneling between the…
Decoherence of a qubit by non-Gaussian noise at an arbitrary working point
J. Bergli, Y. M. Galperin, B. L. Altshuler
The decoherence of a qubit due to a classical non-Gaussian noise with correlation time longer than the decoherence time is discussed for arbitrary working points of the qubit. A me…
