Spectroscopy of phonons and spin torques in magnetic point contacts
I. K. Yanson, Yu. G. Naidyuk, D. L. Bashlakov +4
Phonon spectroscopy is used to investigate the mechanism of current-induced spin torques in nonmagnetic/ferromagnetic (N/F) point contacts. Magnetization excitations observed in th…
Pauli spin blockade in weakly coupled quantum dots
J. Fransson, M. Rasander
In a two-level system, constituted by two serially coupled single level quantum dots, coupled to external leads we find that the current is suppressed in one direction of biasing c…
Complexes of Directed Trees and Independence Complexes
Alexander Engstrom
The theory of complexes of directed trees was initiated by Kozlov to answer a question by Stanley, and later on, results from the theory were used by Babson and Kozlov in their pro…
An analogue of Young's lattice for compositions
Anders Bjorner, Richard Stanley
This paper has been withdrawn by the authors since it was discovered that most of its content was already known.
Bosons and fermions in external fields
Edwin Langmann
Contribution to the Encyclopedia of Mathematical Physics (Elsevier, 2006): a brief and (hopefully) pedagogical introduction to quantum field theory models describing particles in e…
Optimal focusing for maximal collection of entangled narrow-band photon pairs into single-mode fibers
Daniel Ljunggren, Maria Tengner
We present a theoretical and experimental investigation of the emission characteristics and the flux of photon pairs generated by spontaneous parametric downconversion in quasi-pha…
