Quantum phases in endofullerene zigzag chains
Tobias Serwatka, Muhammad Shaeer Moeed, Roger G. Melko +1
We employ large-scale density matrix renormalization group calculations to study the quantum phases of dipolar molecules confined in bent (zigzag) endofullerene chains, as a functi…

Pair Approximating the Action For Molecular Rotations in Path Integral Monte Carlo
Shaeer Moeed, Tobias Serwatka, Pierre-Nicholas Roy
Typical path integral Monte Carlo approaches use the primitive approximation to compute the probability density for a given path. In this work, we develop the pair Discrete Variabl…

Path integral Monte Carlo in a discrete variable representation with Gibbs sampling: dipolar planar rotor chain
Wenxue Zhang, Muhammad Shaeer Moeed, Andrew Bright +3
In this work, we propose a Path Integral Monte Carlo (PIMC) approach based on discretized continuous degrees of freedom and rejection-free Gibbs sampling. The ground state properti…
