Search for Dark Sector by Repurposing the UVX Brazilian Synchrotron
L. Duarte, L. Lin, M. Lindner +6
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, c…
Phase-Retrieval as a Regularization Problem
Eduardo X. Miqueles, Nathaly L. Archilha, Marcelo R. Dos Anjos +2
It was recently shown that the phase retrieval imaging of a sample can be modeled as a simple convolution process. Sometimes, such a convolution depends on physical parameters of t…
Conductivity of electronic liquid-crystalline mesophases
Rafael M. Fernandes, Jörg Schmalian, Harry Westfahl
We investigate the connection between the transport properties and the thermodynamics of electronic systems with a tendency to form broken-symmetry mesophases evocative of the phys…
Driven dissipative dynamics of spins in quantum dots
Frederico Brito, Harry Westfahl, Amir O. Caldeira +1
We have studied the dissipative dynamics of a driven electronic spin trapped in a quantum dot. We consider the dissipative mechanism as due to the indirect coupling of the electron…
Magnetic structure and critical behavior of GdRhIn: resonant x-ray diffraction and renormalization group analysis
E. Granado, B. Uchoa, A. Malachias +3
The magnetic structure and fluctuations of tetragonal GdRhIn5 were studied by resonant x-ray diffraction at the Gd LII and LIII edges, followed by a renormalization group analysis…
Fluctuation induced first-order phase transitions in a dipolar Ising ferromagnet slab
Rafael M. Fernandes, Harry Westfahl
We investigate the competition between the dipolar and the exchange interaction in a ferromagnetic slab with finite thickness and finite width. From an analytical approximate expre…
