ICE1 2014 Workshop “Información Cuántca en España-1” - Zaragoza, 2014
Measuring topology in complex systems
Instituto de Fisica Fundamental, CSIC, Serrano 113b, 28006, Madrid, Spain
Time-of-flight imaging is a powerful measurement tool for measuring topology in optical lattices . In this talk we will analyze the information provided by these measurements in a model for topological superconductors (which is adiabatically connected to Kitaevs honeycomb model and signals the presence of Majorana modes ) and interacting Chern insulators, and find that entanglement and interactions affect time-of-flight observables in a distinct manner thus making them a resource for characterizing highly correlated systems.
