Photoionisation loading of large Sr+ ion clouds with ultrafast pulses [PDF]
, 2008 This paper reports on photoionisation loading based on ultrafast pulses of singly-ionised strontium ions in a linear Paul trap. We take advantage of an autoionising resonance of Sr neutral atoms to form Sr+ by two-photon absorption of femtosecond pulses ...

Quantum simulation of the dynamical Casimir effect with trapped ions
New Journal of Physics, 2016 Quantum vacuum fluctuations are a direct manifestation of Heisenberg’s uncertainty principle. The dynamical Casimir effect (DCE) allows for the observation of these vacuum fluctuations by turning them into real, observable photons.

Decoherence and Loss of Entanglement in Acoustic Black Holes [PDF]
, 2012 We studied the process of decoherence in acoustic black holes. We focused on the ion trap model proposed by Horstmann et al. (Phys. Rev. Lett. 104, 250403 (2010)) but the formalism is general to any experimental implementation. For that particular setup,

Fast separation of two trapped ions
New Journal of Physics, 2015 We design fast protocols to separate or recombine two ions in a segmented Paul trap. By inverse engineering the time evolution of the trapping potential composed of a harmonic and a quartic term, it is possible to perform these processes in a few ...

Controlling the transport of an ion: classical and quantum mechanical solutions
New Journal of Physics, 2014 The accurate transport of an ion over macroscopic distances represents a challenging control problem due to the different length and time scales that enter and the experimental limitations on the controls that need to be accounted for.

Exact solution of the ion-laser interaction in all regimes
, 2010 We show that in the trapped ion-laser interaction all the regimes may be considered analytically. We may solve not only for different laser intensities, but also away from resonance and from the Lamb-Dicke regime. It is found a dispersive Hamiltonian for

Mesoscopic entanglement induced by spontaneous emission in solid-state quantum optics [PDF]
, 2013 Implementations of solid-state quantum optics provide us with devices where qubits are placed at fixed positions in photonic or plasmonic one-dimensional waveguides.

Influence of ion movement on the bound electron g-factor
, 2015 In the relativistic description of atomic systems in external fields the total momentum and the external electric field couple to the angular momentum of the individual particles.

Dirac oscillator in DSR: A comparative study of Magueijo–Smolin and Amelino-Camelia models
Physics Letters BThis investigation examines the one-dimensional Dirac oscillator in the framework of Doubly Special Relativity (DSR), with a comparative analysis of the Magueijo–Smolin (MS) and Amelino-Camelia (AC) formulations up to order O(E2/k2).

The Electrostatic Ion Beam Trap : a mass spectrometer of infinite mass range [PDF]
, 2013 We study the ions dynamics inside an Electrostatic Ion Beam Trap (EIBT) and show that the stability of the trapping is ruled by a Hill's equation. This unexpectedly demonstrates that an EIBT, in the reference frame of the ions works very similar to a ...
