Two-axis two-spin squeezed states
Jonas Kitzinger, Manish Chaudhary, Manikandan Kondappan +2
The states generated by the two-spin generalization of the two-axis countertwisting Hamiltonian are examined. We analyze the behavior at both short and long timescales, by calculat…
Cooper pair polaritons in cold fermionic atoms within a cavity
Amaury Dodel, Alexander Pikovski, Igor Ermakov +4
We formulate a Bardeen-Cooper-Schriffer (BCS) theory of quasiparticles in a degenerate Fermi gas strongly coupled to photons in a optical cavity. The elementary photonic excitation…
Phase diffusion in trapped-atom interferometers
Valentin Ivannikov, Andrei I. Sidorov
We evaluate the performance and phase diffusion of trapped Rb atoms in an atom-chip sensor with Ramsey interferometry and Hahn's spin echo in the time and phase domains. We…
Split spin-squeezed Bose-Einstein Condensates
Yumang Jing, Matteo Fadel, Valentin Ivannikov +1
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a …
Ultracold atom interferometry with pulses of variable duration
Valentin Ivannikov
We offer interferometry models for thermal ensembles with one-body losses and the phenomenological inclusion of perturbations covering most of the thermal atom experiments. A possi…
