Dynamical mean field theory with the density matrix renormalization group
(American Physical Society, 2004-12)
A new algorithm to solve the dynamical mean field theory (DMFT) equations of strongly correlated models exploiting the DMRG methodology was presented. The methods uses the density matrix renormalization group technique to ...

Current jumps in flat-band ladders with Dzyaloshinskii-Moriya interactions
(American Physical Society, 2020-11-20)
Localized magnons states, due to flat bands in the spectrum, is an intensely studied phenomenon and can be found in many frustrated magnets of different spatial dimensionality. The presence of Dzyaloshinskii-Moriya (DM) ...
All the entropies on the light-cone
(Springer, 2018-05)
We determine the explicit universal form of the entanglement and Renyi entropies, for regions with arbitrary boundary on a null plane or the light-cone. All the entropies are shown to saturate the strong subadditive ...

Site trimer percolation on square lattices
(American Physical Society, 2015-07)
Percolation of site trimers (k-mers with k = 3) is investigated in a detailed way making use of an analyticalmodel based on renormalization techniques in this problem. Results are compared to those obtained here bymeans ...
Critical behavior of a nonlocal φ4 field theory and asymptotic freedom
(American Physical Society, 2018-09)
The critical behavior of a nonlocal scalar field theory is studied. This theory has a nonlocal kinetic term which involves a real power 1-2α of the Laplacian. The interaction term is the usual local φ4 interaction. The ...
Noncommutative U(1) gauge theory from a worldline perspective
(Springer, 2015-11)
Abstract: We study pure noncommutative U(1) gauge theory representing its one-loop effective action in terms of a phase space worldline path integral. We write the quadratic action using the background field method to keep ...
