text: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. By analogy with the bipolaron, we introduce the biangulon quasiparticle
describing two rotating molecules that align with respect to each other due to
the effective attractive interaction mediated by the excitations of the bath.
We study this system in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, we introduce a diagonalization scheme that allows us to describe
the transition from two separated angulons to a biangulon as a function of the
distance between the two molecules.

text: "The oft-quoted dictum by Arthur Schawlow: ``A diatomic molecule has one atom
too many'' has been disavowed. Inspired by the possibility to experimentally manipulate
and enhance chemical reactivity in helium nanodroplets, we investigate the rotation
of coupled cold molecules in the presence of a many-body environment.\r\nIn this
thesis, we introduce new variational approaches to quantum impurities and apply
them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other
point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed
out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox,
we reveal the self-localization transition for the angulon quasiparticle. We show
that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath
coupling already at the mean-field level. The transition is accompanied by the
spherical-symmetry breaking of the angulon ground state and a discontinuity in
the first derivative of the ground-state energy. Moreover, the type of symmetry
breaking is dictated by the symmetry of the microscopic impurity-bath interaction,
which leads to a number of distinct self-localized states. \r\nFor the system
containing multiple impurities, by analogy with the bipolaron, we introduce the
biangulon quasiparticle describing two rotating molecules that align with respect
to each other due to the effective attractive interaction mediated by the excitations
of the bath. We study this system from the strong-coupling regime to the weak
molecule-bath interaction regime. We show that the molecules tend to have a strong

and an additional spectral instability, where resonant angular momentum transfer
between the molecules and the bath takes place. Finally, we introduce a diagonalization

text: Problems involving quantum impurities, in which one or a few particles are
interacting with a macroscopic environment, represent a pervasive paradigm, spanning
across atomic, molecular, and condensed-matter physics. In this paper we introduce
new variational approaches to quantum impurities and apply them to the Fröhlich
polaron–a quasiparticle formed out of an electron (or other point-like impurity)
in a polar medium, and to the angulon–a quasiparticle formed out of a rotating
molecule in a bosonic bath. We benchmark these approaches against established
theories, evaluating their accuracy as a function of the impurity-bath coupling.

text: A sliver is a tetrahedron whose four vertices lie close to a plane and whose
perpendicular projection to that plane is a convex quadrilateral with no short
edge. Slivers are both undesirable and ubiquitous in 3-dimensional Delaunay triangulations.
Even when the point-set is well-spaced, slivers may result. This paper shows that
such a point set permits a small perturbation whose Delaunay triangulation contains
no slivers. It also gives deterministic algorithms that compute the perturbation
of n points in time O(n log n) with one processor and in time O(log n) with O(n)
processors.
