Microwave quantum optics with an artificial atom in one-dimensional open space
New Journal of Physics, 2013 We address recent advances in microwave quantum optics with artificial atoms in one-dimensional (1D) open space. This field relies on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a 1D open ...

Experimental proof of quantum Zeno-assisted noise sensing
New Journal of Physics, 2019 In the ideal quantum Zeno (QZ) effect, repeated quantum projective measurements can freeze the coherent dynamics of a quantum system. However, in the weak QZ regime, measurement back-actions can allow the sensing of semi-classical field fluctuations.

An investigation on the mechanics of nanometric cutting and the development of its test-bed [PDF]
, 2003 The mechanics of machining at a very small depth of cut (100 nm or less) is not well understood. The chip formation physics, cutting forces generation, resulting temperatures and the size effects significantly affect the efficiency of the process and ...

Double light-cone dynamics establish thermal states in integrable 1D Bose gases
New Journal of Physics, 2018 We theoretically investigate the non-equilibrium dynamics in a quenched pair of one-dimensional Bose gases with density imbalance. We describe the system using its low-energy effective theory, the Luttinger liquid model.

An on-chip optical lattice for cold atom experiments
, 2015 An atom-chip-based integrated optical lattice system for cold and ultracold atom applications is presented. The retro-reflection optics necessary for forming the lattice are bonded directly to the atom chip, enabling a compact and robust on-chip optical ...

Combined chips for atom-optics [PDF]
, 2005 We present experiments with Bose-Einstein condensates on a combined atom chip. The combined structure consists of a large-scale "carrier chip" and smaller "atom-optics chips", containing micron-sized elements. This allows us to work with condensates very

Coherent transport by adiabatic passage on atom chips [PDF]
, 2013 Adiabatic techniques offer some of the most promising tools for achieving high-fidelity control of the center-of-mass degree of freedom of single atoms.

Suppression and enhancement of decoherence in an atomic Josephson junction
, 2015 We examine the role of interactions for a Bose gas trapped in a double-well potential ("Bose-Josephson junction") when external noise is applied and the system is initially delocalized with equal probability amplitudes in both sites.

Spatially Resolved Excitation of Rydberg Atoms and Surface Effects on an Atom Chip [PDF]
, 2010 We demonstrate spatially resolved, coherent excitation of Rydberg atoms on an atom chip. Electromagnetically induced transparency (EIT) is used to investigate the properties of the Rydberg atoms near the gold coated chip surface.

Two-point phase correlations of a one-dimensional bosonic Josephson junction
, 2011 We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable double well potential on an atom chip. Matter wave interferometry gives direct access to the relative phase field, which reflects the interplay of thermally ...
