The bilinear-biquadratic spin-1 chain undergoing quadratic Zeeman effect
G. De Chiara, M. Lewenstein, A. Sanpera
The Heisenberg model for spin-1 bosons in one dimension presents many different quantum phases including the famous topological Haldane phase. Here we study the robustness of such…
Josephson oscillations in binary mixtures of F=1 spinor BECs
B. Julia-Diaz, M. Guilleumas, M. Lewenstein +2
We analyze theoretically Josephson oscillations in a mixture of two Zeeman states of a spinor Bose-Einstein condensate in a double-well potential. We find that in the strongly pola…
Quantum polarization spectroscopy of correlations in attractive fermionic gases
T. Roscilde, M. Rodriguez, K. Eckert +4
We show how spin-spin correlations, detected in a non-destructive way via spatially resolved quantum polarization spectroscopy, strongly characterize various phases realized in tra…
Three level atom optics in dipole traps and waveguides
K. Eckert, J. Mompart, R. Corbalan +2
An analogy is explored between a setup of three atomic traps coupled via tunneling and an internal atomic three-level system interacting with two laser fields. Within this scenario…
Differential atom interferometry beyond the standard quantum limit
K. Eckert, P. Hyllus, D. Bruss +6
We analyze methods to go beyond the standard quantum limit for a class of atomic interferometers, where the quantity of interest is the difference of phase shifts obtained by two i…
Three level atom optics via the tunneling interaction
K. Eckert, M. Lewenstein, R. Corbalan +3
Three level atom optics (TLAO) is introduced as a simple, efficient and robust method to coherently manipulate and transport neutral atoms. The tunneling interaction among three tr…
