Query: Thermal and Quantum Fluctuation Effects in Quasiperiodic Systems in
  External Potentials   We analyze the many-body phases of an ensemble of particles interacting via a
Lifshitz--Petrich--Gaussian pair potential in a harmonic confinement. We focus
on specific parameter regimes where we expect decagonal quasiperiodic cluster
arrangements. Performing classical Monte Carlo as well as path integral quantum
Monte Carlo methods, we numerically simulate systems of a few thousand
particles including thermal and quantum fluctuations. Our findings indicate
that the competition between the intrinsic length scale of the harmonic
oscillator and the wavelengths associated to the minima of the pair potential
generically lead to a destruction of the quasicrystalline pattern. Extensions
of this work are also discussed.
