Few-electron systems in a quantum dot in a magnetic field: The Wigner molecule and paired electron phases
(2006)We have developed a variational many-body description for few-electron systems in a parabolic quantum dot in an external magnetic field. The ground state energy of the electronic system has been theoretically investigated ...

Simulating a CP-violating topological term in gauge theories
(2012)We present recent results on the θ-dependence of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term in the Lagrangian. In particular, we study the scaling behavior of ...

SU(N) gauge theories in the presence of a topological term
(2008)We review recent results on the θ dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term F F in the Lagrangian. In ...
