Matrix factorizations for nonaffine LG-models [PDF]

open access: yes, 2011
We propose a natural definition of a category of matrix factorizations for nonaffine Landau-Ginzburg models. For any LG-model we construct a fully faithful functor from the category of matrix factorizations defined in this way to the triangulated ...

A hybrid quantum eraser scheme for characterization of free-space and fiber communication channels

open access: yes, 2017
We demonstrate a simple projective measurement based on the quantum eraser concept that can be used to characterize the disturbances of any communication channel.

Collective coordinates of the Skyrme model coupled with fermions

open access: yes, 2003
The problem of construction of fiber bundle over the moduli space of the Skyrme model is considered. We analyse an extension of the original Skyrme model which includes the minimal interaction with fermions.
