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…
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…
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…
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…
