Charge instabilities and topological phases in the extended Hubbard model on the honeycomb lattice with enlarged unit cell
Adolfo G. Grushin, Eduardo V. Castro, Alberto Cortijo +3
We study spontaneous symmetry breaking in a system of spinless fermions in the Honeycomb lattice paying special emphasis to the role of an enlarged unit cell on time reversal symme…
First asteroseismic limits on the nature of dark matter
Jordi Casanellas, Ilídio Lopes
We report the first constraints on the properties of weakly interacting low-mass dark matter (DM) particles using asteroseismology. The additional energy transport mechanism due to…
Superradiant instabilities in astrophysical systems
Helvi Witek, Vitor Cardoso, Akihiro Ishibashi +1
Light bosonic degrees of freedom have become a serious candidate for dark matter. The evolution of these fields around curved spacetimes is poorly understood but is expected to dis…
Nonlinear anomalous Hall effect and negative magnetoresistance in a system with random Rashba field
V. K. Dugaev, M. Inglot, E. Ya. Sherman +2
We predict two spin-dependent transport phenomena in two-dimensional electron systems, which are induced by spatially fluctuating Rashba spin-orbit interaction. When the electron g…
Quark condensate for various heavy flavors
Dmitri Antonov, Jose Emilio F. T. Ribeiro
The quark condensate is calculated within the world-line effective-action formalism, by using for the Wilson loop an ansatz provided by the stochastic vacuum model. Starting with t…
CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release
CALIFA collaboration, B. Husemann, K. Jahnke +74
We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…
