STM conductance of Kondo impurities on open and structured surfaces
P. S. Cornaglia, C. A. Balseiro
We study the scanning tunneling microscopy response for magnetic atoms on open and structured surfaces using Wilson's renormalization group. We observe Fano resonances associated w…
Transport through quantum dots in mesoscopic circuits
P. S. Cornaglia, C. A. Balseiro
We study the transport through a quantum dot, in the Kondo Coulomb blockade valley, embedded in a mesoscopic device with finite wires. The quantization of states in the circuit tha…
Survival in the replicator model: Dynamics and statistics
Sebastian Bouzat, Damian Zanette
We study the multi-species replicator model with linear fitness and random fitness matrices of various classes. By means of numerical resolution of the replicator equations, we det…
Size driven phase transitions in pinned vortex systems
P. S. Cornaglia, M. F. Laguna
We model a tridimensional vortex system in a sample with square superficial pinning in the top surface and obtain the ground state structures as a function of the sample thickness.…
Spectral densities of Kondo impurities in nanoscopic systems
P. S. Cornaglia, C. A. Balseiro
We present results for the spectral properties of Kondo impurities in nanoscopic systems. Using Wilson's renormalization group we analyze the frequency and temperature dependence o…
Quantum stability of defects for a Dirac field coupled to a scalar field in 2+1 dimensions
C. D. Fosco
We study the Euclidean effective action and the full fermion propagator for a Dirac field in the presence of a scalar field with a domain wall defect, in 2+1 dimensions. We include…
