Loop Bifurcation and Magnetization Rotation in Exchange Biased Ni/FeF2
Justin Olamit, Elke Arenholz, Zhi-Pan Li +6
Exchange biased Ni/ FeF2 films have been investigated using vector coil vibrating sample magnetometry as a function of the cooling field strength H_FC. In films with epitaxial FeF2…
On nonlinear evolution and supraluminal communication between finite quantum systems
M. Ferrero, D. Salgado, J. L. Sanchez-Gomez
We revise the 'no-signaling' condition for the supraluminal communication between two spatially separated finite quantum systems of arbitrary dimensions, thus generalizing a simila…
Building Chinese Lexicons from Scratch by Unsupervised Short Document Self-Segmentation
Daniel Gayo-Avello
Chinese text segmentation is a well-known and difficult problem. On one side, there is not a simple notion of "word" in Chinese language making really hard to implement rule-based…
Lateral length scales in exchange bias
Igor V. Roshchin, O. Petracic, R. Morales +3
When a ferromagnet is in proximity with an antiferromagnet, lateral length scales such as the respective magnetic domain sizes drastically affect the exchange bias. Bilayers of FeF…
A simple proof of the Jamiolkowski criterion for complete positivity of linear maps
D. Salgado, J. L. Sanchez-Gomez, M. Ferrero
We give a simple direct proof of the Jamiolkowski criterion to check whether a linear map between matrix algebras is completely positive or not. This proof is more accesible for ph…
Quantum corrections to the mass of self-dual vortices
A. Alonso Izquierdo, W. Garcia Fuertes, M. de la Torre Mayado +1
The mass shift induced by one-loop quantum fluctuations on self-dual ANO vortices is computed using heat kernel/generalized zeta function regularization methods.
