Physical Review X, 2017 We investigate the switching of the coherent emission mode of a bimodal microcavity device, occurring when the pump power is varied. We compare experimental data to theoretical results and identify the underlying mechanism based on the competition ...

Challenges and advances of positronium Bose-Einstein condensation
AIP Advances, 2019 While scientists in the USA have accomplished Bose-Einstein Condensation (BEC) of inert gas and alkaline atoms successfully, a challenging question comes into the other’s mind why not BEC of Positronium (Ps), even though, its lowest lifetime (142 ns)?

Bose-Einstein Condensation in inhomogeneous Josephson arrays
, 2000 We show that spatial Bose-Einstein condensation of non-interacting bosons occurs in dimension d < 2 over discrete structures with inhomogeneous topology and with no need of external confining potentials.

Alternative techniques for the production and manipulation of ultracold atoms
, 2012 This Thesis contains details of the construction and characterisation of a compact apparatus for the cooling of ultracold atoms to quantum degeneracy, and their manipulation in flexible holographic optical traps. We have designed and built two iterations

Organic polaritons : modelling the effect of vibrational dressing
, 2015 This thesis is a theoretical study of the effects of vibrational degrees of freedom on the polariton physics. The work is motivated by recent experiments, which show that by allowing light to strongly couple with organic matter (inside a microcavity ...

Bose-Einstein Condensation of 84Sr
, 2009 We report Bose-Einstein condensation of Sr84 in an optical dipole trap. Efficient laser cooling on the narrow intercombination line and an ideal s-wave scattering length allow the creation of large condensates (N0∼3×105) even though the natural abundance
