Tuning the order of a deconfined quantum critical point
Anika Götz, Fakher F. Assaad, Natanael C. Costa
We consider a Su-Schrieffer-Heeger model in the assisted hopping limit, where direct electron hopping is subdominant. At fixed electron-phonon coupling and in the absence of Coulom…
Evidence of controlling vortex matter via a superconducting Nanobridge
C. A. Aguirre, J. Faundez, P. Diaz +4
We theoretically investigate the magnetic response on a three-dimensional superconducting nanobridge system, which is compound of two parallel parallelepiped (samples) connected th…
Magnetism and metal-insulator transitions in the anisotropic kagome lattice
Lucas O. Lima, Andressa R. Medeiros-Silva, Raimundo R. dos Santos +2
The interest in the physical properties of kagome lattices has risen considerably. In addition to the synthesis of new materials, the possibility of realizing ultracold atoms on an…
Magnetic and singlet phases in the three-dimensional periodic Anderson Model
Wiliam S. Oliveira, Thereza Paiva, Richard T. Scalettar +1
Heavy fermion materials are compounds in which localized -orbitals hybridize with delocalized ones, leading to quasiparticles with large renormalized masses. The presence of…
Ferromagnetism beyond Lieb's theorem
Natanael C. Costa, Tiago Mendes-Santos, Thereza Paiva +2
The noninteracting electronic structures of tight binding models on bipartite lattices with unequal numbers of sites in the two sublattices have a number of unique features, includ…
Impurities near an Antiferromagnetic-Singlet Quantum Critical Point
T. Mendes, N. Costa, G. Batrouni +4
Heavy fermion systems, and other strongly correlated electron materials, often exhibit a competition between antiferromagnetic (AF) and singlet ground states. Using exact Quantum M…
