The recent developments of microgravity experiments with ultracold atoms have produced a
relevant boost in the study of shell-shaped ellipsoidal Bose-Einstein condensates. For …

One of the most commonly employed methods to study doped helium clusters is the path
integral Monte Carlo (PIMC) approach. In this review we present results of recent …

We study a system of 2D trapped bosons in a quasiperiodic potential via ab initio path
integral Monte Carlo simulations, focusing on its finite-temperature properties, which have …

We propose an approach to compute the ground state properties of collections of interacting
asymmetric top molecules based on the density matrix renormalization group method …

Helium is the only solvent within which molecules can “freely” rotate, albeit with an
increased moment of inertia relative to the gas phase. Evidence for this can be obtained by …

A density functional theory based on polymer self-consistent field theory is applied to
systems of two atoms in order to show that this approach is capable of predicted molecular …

Free energy calculations are a crucial part of understanding chemical systems but are often
computationally expensive for all but the simplest of systems. Various enhanced sampling …

We introduce a quantum Monte Carlo algorithm to measure the Rényi entanglement
entropies in systems of interacting bosons in the continuum. This approach is based on a …

Superfluid helium has not only fascinated scientists for centuries but is also the ideal matrix
for the investigation of chemical systems under ultra-cold conditions in helium nanodroplet …

Little is known about how rotating molecular ions interact with multiple He 4 atoms and how
this relates to microscopic superfluidity. Here, we use infrared spectroscopy to investigate …
