Quantum critical behavior in chains of hindered dipolar planar rotors
Wenxue Zhang, Muhammad Shaeer Moeed, Estevao De Oliveira +2
We study the ground-state properties of linear chains of dipolar planar rotors hindered by a six-fold on-site potential, a model motivated by water molecules confined in the hexago…
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…
Effective theory of quantum phases in the dipolar planar rotor chain
Estêvão V. B. de Oliveira, Muhammad Shaeer Moeed, Pierre-Nicholas Roy
In this work, we develop a theoretical description of the collective behavior of interacting dipolar planar rotors by using time independent perturbation theory and a small angle q…
Superfluidity in the spin-1/2 XY model with power-law interactions
Muhammad Shaeer Moeed, Costanza Pennaforti, Adrian Del Maestro +1
In trapped-ion quantum simulators, effective spin-1/2 XY interactions can be engineered via laser-induced coupling between internal atomic states and collective phonon modes. In th…
Qubit encodings for lattices of dipolar planar rotors
Muhammad Shaeer Moeed, James Brown, Alexander Ibrahim +2
Near term quantum devices have recently garnered significant interest as promising candidates for investigating difficult-to-probe regimes in many-body physics. To this end, variou…
Path Integral Monte Carlo in the Angular Momentum Basis for a Chain of Planar Rotors
Estêvão de Oliveira, Muhammad Shaeer Moeed, Pierre-Nicholas Roy
We introduce a Path Integral Monte Carlo (PIMC) approach that uses the angular momentum representation for the description of interacting rotor systems. Such a choice of representa…
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…
Improving the Time Stability of Superconducting Planar Resonators
M. S. Moeed, C. T. Earnest, J. H. Béjanin +2
Quantum computers are close to become a practical technology. Solid-state implementations based, for example, on superconducting devices strongly rely on the quality of the constit…
