Formation of helical ion chains
Ramil Nigmatullin, Adolfo del Campo, Gabriele De Chiara +3
We study the nonequilibrium dynamics of the linear to zigzag structural phase transition exhibited by an ion chain confined in a trap with periodic boundary conditions. The transit…
Fidelity of fermionic atom-number states subjected to tunneling decay
M. Pons, D. Sokolovski, A. del Campo
Atom-number states are a valuable resource for ultracold chemistry, atom interferometry and quantum information processing. Recent experiments have achieved their deterministic pre…
The asymptotic Bethe ansatz solution for one-dimensional SU(2) spinor bosons with finite range Gaussian interactions
J. Y. Lee, X. W. Guan, A. del Campo +1
We propose a one-dimensional model of spinor bosons with SU(2) symmetry and a two-body finite range Gaussian interaction potential. We show that the model is exactly solvable when…
Long-time behavior of many-particle quantum decay
A. del Campo
While exponential decay is ubiquitous in Nature, deviations at both short and long times are dictated by quantum mechanics. Non-exponential decay is known to arise due to the possi…
Frictionless quantum quenches in ultracold gases: a quantum dynamical microscope
A. del Campo
In this article, a method is proposed to spatially scale up a trapped ultracold gas while conserving the quantum correlations of the initial many-body state. For systems supporting…
