From exotic lattices to detection of topological order and nonlocality: Recent progress at ICFO.
I present a report on some of the recent activities in the Quantum Optics Theory group at ICFO. I will choose on demand and discuss few of the current projects of the group: from proximity effects in bilayer brick-square lattice, through detection of Zak phase in quantum random walk and detection of Chern numbers in Floquet topological bands, to detection of non-locality in 1D systems via measurements of energy, and quantum Brownian motion revisited.
