DESCRIPTION:Speakers: Juan José Mayorga Bonilla (Universidad Nacional de 
 Colombia)\nThis work presents an analytical Green's function study of one-
 dimensional topological models aimed at connecting their equilibrium spect
 ral properties to nonequilibrium quantum transport. Working in the continu
 um limit\, we derive exact expressions for the retarded Green's function o
 f the bulk\, the semi-infinite chain\, and the finite chain\, computing th
 e Local Density of States (LDOS) in each geometry and tracing the progress
 ive emergence of topologically protected boundary states\, which are absen
 t in the bulk spectrum. By this framework\, we model a two-terminal juncti
 on consisting of a finite topological chain contacted by two normal metall
 ic leads and using the Keldysh Non-Equilibrium Green Function formalism\, 
 we compute the transmission function and analyze the nonequilibrium transp
 ort properties of the junction. This work provides a fully analytical and 
 unified framework connecting bulk topology\, boundary spectral properties\
 , and out-of-equilibrium current statistics in topological junctions.\n\nh
