We discuss via general arguments and examples when and why the steady nonequilibrium
heat capacity vanishes with temperature. The framework is that of Markov jump processes …

We present the design, implementation, and detailed experimental characterization and
comparison with numerical simulations of twodimensional magneto-optical traps (MOTs) of …

In this paper, we discuss some aspects of the energetics of a quantum Brownian particle
placed in a harmonic trap, also known as the dissipative quantum oscillator. Based on the …

We analyse the long-time tails of a charged quantum Brownian particle in a harmonic
potential in the presence of a magnetic field using the Quantum Langevin Equation as a …

We report the characterization of the forced damped harmonic oscillations of^ 133 C s atoms
in a magneto-optical trap, which was realized by modulating the intensity of the lasers …

The position response of a particle subjected to a perturbation is of general interest in
physics. We study the modification of the position response function of an ensemble of cold …

We use the quantum Langevin equation as a starting point to study the response function,
the position–velocity correlation function and the velocity autocorrelation function of a …

We present the design, implementation and detailed experimental characterization of two-
dimensional Magneto-optical traps (MOT) of bosonic $^{23} $ Na and $^{39} $ K atoms for …

We infer the damping coefficient of cold atoms in a magneto-optical trap by capturing images
of the expanding atomic cloud in optical molasses, followed by a measurement of the …

This thesis discusses the study of ultracold 85 Rb atoms in both molasses and optical
lattices, with a focus on the implementation of a fluorescence imaging system to characterize …
