Time and category information in pattern-based codes
Hugo Gabriel Eyherabide, Inés Samengo
Sensory stimuli are usually composed of different features (the what) appearing at irregular times (the when). Neural responses often use spike patterns to represent sensory inform…
A model for the emergence of social organization in primates
M. N. Kuperman
Recent studies have established an apparent relationship between the repertoire of signals used for communication and neocortex size of different species of primates and the topolo…
Inertial forces and dissipation on accelerated boundaries
C. D. Fosco, F. C. Lombardo, F. D. Mazzitelli
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in , , and dimensions. These matter fields describe t…
Quantum phase diagram of the half filled Hubbard model with bond-charge interaction
A. O. Dobry, A. A. Aligia
Using quantum field theory and bosonization, we determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction in addition to the usual C…
Edge channel mixing induced by potential steps in an integer quantum Hall system
D. Venturelli, V. Giovannetti, F. Taddei +4
We investigate the coherent mixing of co-propagating edge channels in a quantum Hall bar produced by step potentials. In the case of two edge channels it is found that, although a…
U-dual fluxes and Generalized Geometry
G. Aldazabal, E. Andres, P. G. Camara +1
We perform a systematic analysis of generic string flux compactifications, making use of Exceptional Generalized Geometry (EGG) as an organizing principle. In particular, we establ…
