TÍTULO: MANIFESTATIONS OF SPIN-ORBIT COUPLING AND TOPOLOGY IN
OUT-OF-EQUILIBRIUM HYBRID SUPERCONDUCTING SYSTEMS 

EXPONE: NAYANA SHAH UNIVERSITY OF CINCINNATI 

RESUMEN: Recently there has been a lot of excitement generated by the
possibility of realizing and detecting Majorana fermions within the
arena of condensed matter physics and its potential implication for
topological quantum computing. Although already at the end of twentieth
century emergent Majorana end-states were shown to exist in a
theoretical model of spinless p-wave superconductor (Kitaev) chain, it
was only a decade later that proposals to experimentally realize such a
model emerged. These were motivated by the discovery of topological
insulators that ushered a new era of so-called symmetry-protected
topological phases but also stemmed from existent studies of hybrid
superconductor-ferromagnet systems that form the basis of another highly
active area of superconducting spintronics. At the heart of these
proposals are ways to judiciously use spin-orbit coupling in
artificially designed hybrid settings containing conventional s-wave
superconductors to effectively create topological superconductors.
Making sense of the corresponding experiments requires employing and
developing complementary theoretical frameworks to fundamentally
comprehend the out-of-equilibrium transport behavior in these systems. I
will outline the steps we have taken in that direction and the questions
that remain to be answered.
