Monte Carlo Hamiltonian: the Linear Potentials
Xiang-Qian Luo, Jin-Jiang Liu, Chun-Qing Huang +2
We further study the validity of the Monte Carlo Hamiltonian method. The advantage of the method, in comparison with the standard Monte Carlo Lagrangian approach, is its capability…
Supersymmetric Calogero-Moser-Sutherland models: superintegrability structure and eigenfunctions
P. Desrosiers, L. Lapointe, P. Mathieu
We first review the construction of the supersymmetric extension of the (quantum) Calogero-Moser-Sutherland (CMS) models. We stress the remarkable fact that this extension is compl…
Jack polynomials in superspace
P. Desrosiers, L. Lapointe, P. Mathieu
This work initiates the study of {\it orthogonal} symmetric polynomials in superspace. Here we present two approaches leading to a family of orthogonal polynomials in superspace th…
The su(2)_{-1/2} WZW model and the beta-gamma system
F. Lesage, P. Mathieu, J. Rasmussen +1
The bosonic beta-gamma ghost system has long been used in formal constructions of conformal field theory. It has become important in its own right in the last few years, as a build…
Locally wrapped D-branes
Frederic Leblond, Luc Marleau
We find examples in string theory of locally wrapped D-branes. These excitations mimic skyrmions in that they correspond to topological excitations of the scalar fields parametrizi…
Graded parafermions: standard and quasi-particle bases
P. Jacob, P. Mathieu
Two bases of states are presented for modules of the graded parafermionic conformal field theory associated to the coset $\osp(1,2)_k/\uh(1)$. The first one is formulated in terms…
