Subbands in the doped two-orbital Kanamori-Hubbard model
(American Physical Society, 2020-12)
We calculate and resolve with unprecedented detail the local density of states (DOS) and momentum-dependent spectral functions at zero temperature of one of the key models for strongly correlated electron materials, the ...
Helium on planar and nanostructured alkali-metal surfaces
(American Physical Society, 2009-12)
We investigate the effects (on the wetting characteristics of helium below 3 K) of tailoring an alkali-metal surface by incorporating a regular array of nanoscopic indentations. We establish the prewetting line of helium ...
Discord and information deficit in the XX chain

Ultracold bosons in random lattice potentials
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2023-04-06)
The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ...

Exact correlation functions in particle-reaction models with immobile particles
(IOP PUBLISHING LTDBRISTOL, 2012)
Exact results on particle densities as well as correlators in two models of immobile particles, containing either a single species or else two distinct species, are derived. The models evolve following a descent dynamics ...
Emergent low-energy bound states in the two-orbital Hubbard model
(American Physical Society, 2018-03-30)
A repulsive Coulomb interaction between electrons in different orbitals in correlated materials can give rise to bound quasiparticle states. We study the nonhybridized two-orbital Hubbard model with intra- (inter)orbital ...
