A new family of polynomial identities for computing determinants
Georgy Egorychev
We give new definitions for the determinant over commutative ring , noncommutative ring , noncommutative ring with associative powers, over noncommutat…
Energetically constrained co-tunneling of cold atoms
Andrey R. Kolovsky, Julia Link, Sandro Wimberger
We study under-barrier tunneling for a pair of energetically bound bosonic atoms in an optical lattice with a barrier. We identify conditions under which this exotic molecule tunne…
The Relativistic Fluid Ball as a Stratified Model of an Astrophysical Object
Alexandre M. Baranov, Alexander Yu. Osipov
A relativistic fluid ball with an inhomogeneous static stratified matter configuration is considered. A model of an astrophysical object with this structure of matter is constructe…
The Catastrophe Theory, Petrov's Algebraic Classification and gravitation phase transitions
Alexandre M. Baranov
A close relationship is demonstrated between the catastrophe theory, Petrov's algebraic classification of the gravitational fields and the theory of phase transitions.
Amoebas of complex hypersurfaces in statistical thermodynamics
Mikael Passare, Dmitry Pochekutov, August Tsikh
The amoeba of a complex hypersurface is its image under a logarithmic projection. A number of properties of algebraic hypersurface amoebas are carried over to the case of transcend…
Gap Symmetry in KFe_2As_2 and cos 4θgap component in LiFeAs
S. Maiti, M. M. Korshunov, A. V. Chubukov
We revisit the issue of the gap symmetry in KFe2As2, which is an Fe-pnictide superconductor with only hole pockets. Previous theoretical studies mostly argued for a d-wave gap in K…
