Vibrational mode multiplexing of ultracold atoms
S. Martínez-Garaot, E. Torrontegui, Xi Chen +4
Sending multiple messages on qubits encoded in different vibrational modes of cold atoms or ions along a transmission waveguide requires to merge first and then separate the modes…
Self-consistent tight-binding description of Dirac points moving and merging in two dimensional optical lattices
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We present an accurate ab initio tight-binding model, capable of describing the dynamics of Dirac points in tunable honeycomb optical lattices following a recent experimental reali…
Detecting quantum backflow by the density of a Bose-Einstein Condensate
M. Palmero, E. Torrontegui, M. Modugno +1
Quantum backflow is a classically forbidden effect consisting in a negative flux for states with negligible negative momentum components. It has never been observed experimentally…
