Geometric phases in semiconductor spin qubits: Manipulations and decoherence
Pablo San-Jose, Burkhard Scharfenberger, Gerd Schön +2
We describe the effect of geometric phases induced by either classical or quantum electric fields acting on single electron spins in quantum dots in the presence of spin-orbit coup…
Trionic phase of ultracold fermions in an optical lattice: A variational study
Akos Rapp, Walter Hofstetter, Gergely Zarand
To investigate ultracold fermionic atoms of three internal states (colors) in an optical lattice, subject to strong attractive interaction, we study the attractive three-color Hubb…
Dynamical conductance in the two-channel Kondo regime of a double dot system
A. I. Toth, L. Borda, J. von Delft +1
We study finite-frequency transport properties of the double-dot system recently constructed to observe the two-channel Kondo effect [R. M. Potok et al., Nature 446, 167 (2007)]. W…
Spin dephasing due to a random Berry phase
Pablo San-Jose, Gerd Schön, Alexander Shnirman +1
We investigate relaxation and dephasing of an electron spin confined in a semiconductor quantum dot and subject to spin-orbit coupling. Even in vanishing magnetic field, B = 0, slo…
Inelastic scattering from quantum impurities
G. Zarand, L. Borda
We review the non-perturbative theoretical framework set up recently to compute the inelastic scattering cross section from quantum impurities [G. Zaránd {\it et al.}, Phys. Rev. L…
Theory of inelastic scattering from quantum impurities
L. Borda, L. Fritz, N. Andrei +1
We use the framework set up recently to compute non-perturbatively inelastic scattering from quantum impurities [G. Zaránd {\it et al.}, Phys. Rev. Lett. {\bf 93}, 107204 (2004)] t…
