Quantum effects in with an extra compactified dimension
C. Ccapa Ttira, C. D. Fosco, A. P. C. Malbouisson +1
We evaluate one-loop effects for in the presence of an extra compactified dimension, in a non-trivial vacuum for the gauge field, such that a non-vanishing magnetic flu…
Remarks on the entanglement entropy for disconnected regions
H. Casini, M. Huerta
Few facts are known about the entanglement entropy for disconnected regions in quantum field theory. We study here the property of extensivity of the mutual information, which hold…
Features of spin-charge separation in the equilibrium conductance through finite rings
Julian Rincon, A. A. Aligia, K. Hallberg
We calculate the conductance through rings with few sites described by the model, threaded by a magnetic flux and weakly coupled to conducting leads at two arbitrary…
Entanglement entropy for a Dirac fermion in three dimensions: vertex contribution
H. Casini, M. Huerta, L. Leitao
In three dimensions there is a logarithmically divergent contribution to the entanglement entropy which is due to the vertices located at the boundary of the region considered. In…
Localized Spins on Graphene
P. S. Cornaglia, Gonzalo Usaj, C. A. Balseiro
The problem of a magnetic impurity, atomic or molecular, absorbed on top of a carbon atom in otherwise clean graphene is studied using the numerical renormalization group. The spec…
Langevin approach to synchronization of hyperchaotic time-delay dynamics
Adrian A. Budini
In this paper, we characterize the synchronization phenomenon of hyperchaotic scalar non-linear delay dynamics in a fully-developed chaos regime. Our results rely on the observatio…
