Internal spin resistance of spin batteries
K. -V. Pham
For spin batteries we introduce the concept of internal spin resistance which quantifies the amount of backflow from the load to the battery. It allows to relate through a Thevenin…
Response of a spin valve to a spin battery
Khuôn-Viêt Pham
It is shown that spin valves under suitable symmetry conditions exhibit an ON-OFF response to a spin battery, and are therefore perfect spin transistors. While a spin valve driven…
Non-local spin valve in Van der Pauw cross geometry with four ferromagnetic electrodes
K. -V. Pham
We consider a non-local spin valve in a Van der Pauw cross geometry with four ferromagnetic electrodes. Two antiparallel ferromagnets are used as (charge) source and drain while th…
Exact Green's functions and Bosonization of a Luttinger liquid coupled to impedances
K-V Pham
The exact Green's functions of a finite-size Luttinger Liquid (LL) connected to impedances are computed at zero and finite temperature. Bosonization for a LL with Impedance boundar…
Probing the intrinsic shot noise of a Luttinger liquid through impedance matching
K. -V. Pham
We argue that a simple way to bypass reflections at the boundaries of a finite Luttinger liquid (LL) connected to electrodes is to match load and drain impedances to the characteri…
Interface resistances and AC transport in a Luttinger liquid
K. -V. Pham
We consider a Luttinger liquid (LL) connected to two reservoirs when the two sample-reservoir interface resistances and are arbitrary (not necessarily quantized at…
