Scaling of the local quantum uncertainty at quantum phase transitions
I. B. Coulamy, J. H. Warnes, M. S. Sarandy +1
We investigate the local quantum uncertainty (LQU) between a block of L qubits and one single qubit in a composite system of n qubits driven through a quantum phase transition (QPT…
Random gauge field effects on the conductivity of graphene sheets with disordered ripples
Rhonald Burgos, Jesus Warnes, Leandro R. F. Lima +1
We study the effect of disordered ripples on the conductivity of monolayer graphene flakes. We calculate the relaxation times and the Boltzmann conductivities associated with two m…
Edge magnetization and local density of states in chiral nanoribbons
A. R. Carvalho, J. H. Warnes, C. H. Lewenkopf
We study the edge magnetization and the local density of states of chiral graphene nanoribbons using a π-orbital Hubbard model in the mean-field approximation. We show that the inc…
Ground state properties of the disordered spin-one Bose-Hubbard model: a stochastic mean-field theory study
Jesus Herazo Warnes, Eduardo Miranda
We study the ground state of the disordered Bose-Hubbard model for spin-1 particles by means of the stochastic mean-field theory. This approach enables the determination of the pro…
