A Handscomb quantum Monte Carlo study

We investigate the critical relaxational dynamics of the S = 1/2 Heisenberg ferromagnet on a simple cubic lattice within the Handscomb prescription on which it is a diagrammatic series expansion of the partition function that is computed by means of a Monte Carlo procedure. Using a phenomenological renormalization group analysis of graph quantities related to the spin susceptibility and order p...

Wigner molecules in quantum dots: A quantum Monte Carlo study

Semiconductor quantum dots ~QD’s! are small devices containing a tunable number of electrons in an external confinement potential. The significant progress in the fabrication of these devices during the last few years has stimulated an increasing interest in investigating the properties of such systems. From the theoretical point of view, QD’s are ideal many-electron objects for the study of fu...

Quantum Monte Carlo Simulation

Contemporary scientific studies often rely on the understanding of complex quantum systems via computer simulation. This paper initiates the statistical study of quantum simulation and proposes a Monte Carlo method for estimating analytically intractable quantities. We derive the bias and variance for the proposed Monte Carlo quantum simulation estimator and establish the asymptotic theory for ...

Quantum monte carlo.

An outline of a random walk computational method for solving the Schrödinger equation for many interacting particles is given, together with a survey of results achieved so far and of applications that remain to be explored. Monte Carlo simulations can be used to calculate accurately the bulk properties of the light elements hydrogen, helium, and lithium as well as the properties of the isolate...
