New criticality of 1D fermions.

One-dimensional massive quantum particles (or 1 + 1-dimensional random walks) with short-ranged multi-particle interactions are studied by exact renormalization group methods. With repulsive pair forces, such particles are known to scale as free fermions. With finite m-body forces (m = 3, 4, . . .), a critical instability is found, indicating the transition to a fermionic bound state. These unb...

Casimir Effect and Vacuum Fluctuations

Vacuum fluctuations have observable consequences, like the Casimir force between two plates in vacuum. There now exists good agreement between theory and experimental measurements of this force. The role of the Casimir effect in diverse fields such as Quantum Field Theory, Condensed Matter Physics and Atomic Physics etc is discussed. A brief description of current applications to nanotechnology...

Vacuum Casimir energy densities and field divergences at boundaries.

We consider and review the emergence of singular field fluctuations or energy densities at sharp boundaries or point-like field sources in the vacuum. The presence of singular energy densities of a field may be relevant from a conceptual point of view, because they contribute to the self-energy of the system. They could also generate significant gravitational effects. We first consider the case...

Radiative corrections to the Casimir energy and effective field theory

We discuss radiative corrections to the Casimir effect from an effective field theory point of view. It is an improvement and more complete version of a previous discussion by Kong and Ravndal. By writing down the most general effective Lagrangian respecting the symmetries and the boundary conditions, we are able to reproduce earlier results of Bordag, Robaschik and Wieczorek calculated in full...
