MONOLAYER CHARGED QUANTUM FILMS: A QUANTUM SIMULATION STUDY

Monolayer charged quantum films: A quantum simulation study

We use path-integral Monte Carlo (PIMC) to study the effects of adding a long-range repulsive Coulomb interaction to the usual Van der Waals interaction between two atoms of a submonolayer quantum film such as helium on graphite or a pure two-dimensional superfluid. Such interactions frustrate or compete with the natural tendency of the system for phase separation namely to form a macroscopic l...

Simulation of Direct Pumping of Quantum Dots in a Quantum Dot Laser

In this paper, the nonlinear rate equations governing a quantum dot laser isused to simulate the transient as well as the steady-state behaviors of the laser.Computation results show that the rate equations are capable of simulating true behaviorof a quantum dot laser. Then, the pump rates of the rate equations (which show indirectelectrical pumping of the quantum dots through a wetting layer) ...

Quantum Many-Body Simulation using Cavity Coupled Monolayer Excitons

We propose an architecture for quantum simulation of strongly interacting bosons using monolayer excitons in MoS2 quantum dots. The strongly coupled monolayer exciton and cavity photon form polaritons between which the interaction reaches 1 ∼ 10 meV—more than one order of magnitude higher than the state-of-art value. We discuss Mott transition in a chain of coupled cavities driven by photon blo...

Quantum current modeling in nano-transistors with a quantum dot

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...
