Finite temperature current densities and Bose-Einstein condensation in topologically nontrivial spaces
E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature expectation values of the charge and current densities for a complex scalar field with nonzero chemical potential in background of a flat spac…
Exact description of the magnetoelectric effect in the spin-1/2 XXZ-chain with Dzyaloshinskii-Moriya interaction
Michael Brockmann, Andreas Klümper, Vadim Ohanyan
We consider a simple integrable model of a spin chain exhibiting the Magnetoelectric Effect (MEE). Starting from the periodic S=1/2 XXZ-chain with Dzyaloshinskii-Moriya terms, whic…
Exploring the alpha-enhancement of metal-poor planet-hosting stars. The Kepler and HARPS samples
V. Zh. Adibekyan, E. Delgado Mena, S. G. Sousa +5
Recent studies showed that at low metallicities Doppler-detected planet-hosting stars have preferably high alpha-content and belong to the thick disk. We used the reconnaissance sp…
Fermionic current from topology and boundaries with applications to higher-dimensional models and nanophysics
S. Bellucci, A. A. Saharian
We investigate combined effects of topology and boundaries on the vacuum expectation value (VEV) of the fermionic current in the space with an arbitrary number of toroidally compac…
Supernovae and their host galaxies. I. The SDSS DR8 database and statistics
A. A. Hakobyan, V. Zh. Adibekyan, L. S. Aramyan +5
(Abridged) In this first paper of a series, we report the creation of large and well-defined database that combines extensive new measurements and a literature search of 3876 super…
Casimir-Polder interaction between an atom and a conducting wall in cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, H. F. Mota +1
The Casimir-Polder interaction potential is evaluated for a polarizable microparticle and a conducting wall in the geometry of a cosmic string perpendicular to the wall. The genera…
