Shedding light on non-equilibrium dynamics of a spin coupled to fermionic reservoir
Hakan E. Türeci, M. Hanl, M. Claassen +7
A single confined spin interacting with a solid-state environment has emerged as one of the fundamental paradigms of mesoscopic physics. In contrast to standard quantum optical sys…
Microscopic model of critical current noise in Josephson-junction qubits: Subgap resonances and Andreev bound states
Rogerio de Sousa, K. Birgitta Whaley, Theresa Hecht +2
We propose a microscopic model of critical current noise in Josephson-junctions based on individual trapping-centers in the tunnel barrier hybridized with electrons in the supercon…
A quantum criticality perspective on the charging of narrow quantum-dot levels
V. Kashcheyevs, C. Karrasch, T. Hecht +3
Understanding the charging of exceptionally narrow levels in quantum dots in the presence of interactions remains a challenge within mesoscopic physics. We address this fundamental…
Interplay of mesoscopic and Kondo effects for transmission amplitude of few-level quantum dots
Theresa Hecht, Andreas Weichselbaum, Yuval Oreg +1
The magnitude and phase of the transmission amplitude of a multi-level quantum dot is calculated for the mesoscopic regime of level spacing large compared to level width. The inter…
Numerical renormalization group calculation of near-gap peaks in spectral functions of the Anderson model with superconducting leads
Theresa Hecht, Andreas Weichselbaum, Jan von Delft +1
We use the numerical renormalization group method (NRG) to investigate a single-impurity Anderson model with a coupling of the impurity to a superconducting host. Analysis of the e…
Phase lapses in transmission through interacting two-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…
