Lasing without Inversion in Circuit Quantum Electrodynamics
M. Marthaler, Y. Utsumi, D. S. Golubev +2
We study the photon generation in a transmission line oscillator coupled to a driven qubit in the presence of a dissipative electromagnetic environment. It has been demonstrated pr…
Single-qubit lasing in the strong-coupling regime
Stephan André, Pei-Qing Jin, Valentina Brosco +4
Motivated by recent ``circuit QED'' experiments we study the lasing transition and spectral properties of single-qubit lasers. In the strong coupling, low-temperature regime quantu…
Nonlocal conductance via overlapping Andreev bound states in ferromagnet-superconductor heterostructures
Georgo Metalidis, Matthias Eschrig, Roland Grein +1
In a setup where two ferromagnetic electrodes are attached to a superconductor, Andreev bound states are induced at both ferromagnet/superconductor (FM/SC) interfaces. We study how…
Statistics of voltage fluctuations in resistively shunted Josephson junctions
D. S. Golubev, M. Marthaler, Y. Utsumi +1
The intrinsic nonlinearity of Josephson junctions converts Gaussian current noise in the input into non-Gaussian voltage noise in the output. For a resistively shunted Josephson ju…
Conductance of Atomic-Sized Lead Contacts in an Electrochemical Environment
F. -Q. Xie, F. Hüser, F. Pauly +3
Atomic-sized lead (Pb) contacts are deposited and dissolved in an electrochemical environment, and their transport properties are measured. Due to the electrochemical fabrication p…
