A third-order exceptional point effect on the dynamics of a single particle in a time-dependent harmonic trap
Raam Uzdin, Emanuele Dalla Torre, Ronnie Kosloff +1
The time evolution of a single particle in a harmonic trap with time dependent frequency omega(t) is well studied. Nevertheless here we show that, when the harmonic trap is opened…
Universal Rephasing Dynamics after a Quantum Quench via Sudden Coupling of Two Initially Independent Condensates
Emanuele G. Dalla Torre, Eugene Demler, Anatoli Polkovnikov
We consider a quantum quench in which two initially independent condensates are suddenly coupled, and study the subsequent "rephasing" dynamics. For weak couplings, the time-evolut…
Dissipative Preparation of Spin Squeezed Atomic Ensembles in a Steady State
Emanuele G. Dalla Torre, Johannes Otterbach, Eugene Demler +2
We present and analyze a new approach for the generation of atomic spin squeezed states. Our method involves the collective coupling of an atomic ensemble to a decaying mode of an…
Noisy quantum phase transitions: an intuitive approach
Emanuele G. Dalla Torre, Eugene Demler, Thierry Giamarchi +1
Equilibrium thermal noise is known to destroy any quantum phase transition. What are the effects of non-equilibrium noise? In two recent papers we have considered the specific case…
