Characterization of Generalized Coherent States through Intensity-Field Correlations
We show that a simple and experimentally accessible observable, the intensity-field correlation function alone, provides a witness of nonclassicality for Generalized Coherent States.

Observation of Entanglement in an analog cosmological preheating
We observed entanglement between collective excitations in a parametrically excited Bose-Einstein condensate in a configuration analogous to particle creation in cosmological preheating. This observation paves the way towards the experimentally driven study of the late time dynamics in further analogy with cosmological reheating.

Growth dynamics of Faraday waves
We shake an elongated Bose-Einstein condensate and studied the appearance of pattern i.e. collective excitation. We compare the growth of the pattern to analytical model and find a remarkable agreement.

Probing entanglement of two-mode bosonic Gaussian states
In this theoretical work, we show how to quantify entanglement of some two-mode bosonic Gaussian states relying on their full probability distribution i.e. by only counting particles.

Pulse shaping for atomic Bragg diffraction
We have developed a new four-mode atomic interferometer that we propose to use in a Bell test.

Defense and publication of my PhD thesis
We discuss the recent defense and publication of my PhD thesis work entitled "On the entanglement of quasi-particles in a Bose-Einstein Condensate - from Faraday waves to the Dynamical Casimir Effect".

Sub-shot-noise interferometry with two-mode quantum states
We discuss the optimization of quantum enhanced interferometers when taking into account losses.
