1.A. Multispin Coding --References --Notes Added in Proof Quantum Monte Carlo (QMC) first appeared in and similarly was preceded by development of the related calculational methodology.

The success of QMC methods over the past few decades has been remarkable, and this book will clearly demonstrate that success in its discussion of applications. We study by means of exact-diagonalization techniques the ground state of a few-fermion system with strong short-range repulsive interactions trapped by a harmonic potential in one spatial dimension.

Lester, Jr. Department oJChemistry, University of Exact Monte Carlo for few-fermion systems book, Berkeley, CAUSA Preface The solution of the time independent Schr6dinger equation for molecular systems requires the use of modern computers, because analytic solutions are not by: Ground-state properties of a few spin- 1 / 2 ultra-cold fermions confined in a one-dimensional trap are studied by the exact diagonalization method.

In contrast to previous studies, it is not assumed that the projection of a spin of individual particles is fixed. Therefore, the spin is treated as an additional degree of freedom and the global magnetization of the Exact Monte Carlo for few-fermion systems book is established Cited by: 3.

We perform comprehensive Monte Carlo (MC) simulations to study ordering dynamics in the random field Ising model with conserved order parameter (C-RFIM) in d = 2, 3.

The observations from this study are: (a) For a fixed value of the disorder, the correlation function C(r, t) exhibits dynamical scaling. Ideally, for a strongly correlated system, we anticipate that Ω (n) becomes less important with increasing n and the diagrammatic expansion thus converges.

Indeed, for a unitary Fermi gas at the BEC–BCS crossover, the theoretical calculation of Ω (2) at zero temperature gives fairly accurate equation of state, as confirmed by the latest experimental by: Femtosecond probing of few-fermion dynamics and deterministic single-photon gain in a single semiconductor quantum dot.

Thursday, Ma, room The existence, and enigmatic nature, of 'Dark Energy' is one of the biggest theoretical upsets of recent times. In this seminar we present ideas on alternative theoretical and phenomenological approaches to the Dark Energy problem, in particular the issue of whether dark energy is a matter or gravity-based phenomenon, and the ways in which such approaches can been constrained and guided by.
