We report a comprehensive study of the ground-state properties of one and two bosonic
impurities immersed in small one-dimensional optical lattices loaded with a few interacting …

There has been wide interest in beam splitter, quantum tunneling, and double-slit
experiments for a long time. The states of single material particles are typically explained as …

We perform an extensive numerical study on the breathing dynamics of a few-body Bose
polaron setup in a one-dimensional species-selective harmonic trap. The dynamics is …

The desire to further our understanding of complex physical phenomena and exploit
quantum mechanics for useful applications has driven the development of controlled …

Quantum gases at low temperatures provide an ideal testbed for generating, manipulating
and imaging strongly interacting systems. This is granted by the ability to tune many …

There has been wide interest in splitter, quantum tunneling, and double-slit experiments for
a long time. The states of single material particles are typically explained as being …

The main objective of this thesis is to examine how the full configuration interaction quantum
Monte Carlo (FCIQMC) method can be best utilized for studying ultracold Bose gases …
