Highly Entangled Ground States in Tripartite Qubit Systems
Beat Röthlisberger, Jörg Lehmann, D. S. Saraga +2
We investigate the creation of highly entangled ground states in a system of three exchange-coupled qubits arranged in a ring geometry. Suitable magnetic field configurations yield…
Shot noise and spin-orbit coherent control of entangled and spin polarized electrons
J. Carlos Egues, Guido Burkard, D. Saraga +2
We extend our previous work on shot noise for entangled and spin polarized electrons in a beam-splitter geometry with spin-orbit (\textit{s-o}) interaction in one of the incoming l…
Fermi liquid parameters in 2D with spin-orbit interaction
D. S. Saraga, Daniel Loss
We derive analytical expressions for the quasiparticle lifetime tau, the effective mass m*, and the Green's function renormalization factor Z for a 2D Fermi liquid with electron-el…
Coulomb scattering cross-section in a 2D electron gas and production of entangled electrons
D. S. Saraga, B. L. Altshuler, Daniel Loss +1
We calculate the Coulomb scattering amplitude for two electrons injected with opposite momenta in an interacting 2DEG. We include the effect of the Fermi liquid background by solvi…
Coulomb scattering in a 2D interacting electron gas and production of EPR pairs
D. S. Saraga, B. L. Altshuler, Daniel Loss +1
We propose a setup to generate non-local spin-EPR pairs via pair collisions in a 2D interacting electron gas, based on constructive two-particle interference in the spin singlet ch…
Shot noise for entangled and spin-polarized electrons
J. C. Egues, P. Recher, D. S. Saraga +4
We review our recent contributions on shot noise for entangled electrons and spin-polarized currents in novel mesoscopic geometries. We first discuss some of our recent proposals f…
