An exactly solvable model of the Calogero type for the icosahedral group
Oliver Haschke, Werner Ruehl
We construct a quantum mechanical model of the Calogero type for the icosahedral group as the structural group. Exact solvability is proved and the spectrum is derived explicitly.
Light-Cone Formulation of Super D2-Brane
R. Manvelyan, A. Melikyan, R. Mkrtchyan +1
The light-cone Hamiltonian approach is applied to the super D2-brane, and the equivalent area--preserving and U(1) gauge-invariant effective Lagrangian, which is quadratic in the U…
AdS/CFT Correspondence, Poincaré Vacuum State and Greybody Factors in BTZ Black Holes
H. J. W. Müller-Kirsten, Nobuyoshi Ohta, Jian-Ge Zhou
The greybody factors in BTZ black holes are evaluated from 2D CFT in the spirit of AdS/CFT correspondence. The initial state of black holes in the usual calculation of greybody…
Dilute Instanton Gas of an O(3) Skyrme Model
H. J. W. Mueller-Kirsten, S. -N. Tamarian, D. H. Tchrakian +1
The pure-Skyrme limit of a scale-breaking Skyrmed O(3) sigma model in 1+1 dimensions is employed to study the effect of the Skyrme term on the semiclassical analysis of a field the…
Exactly solvable dynamical systems in the neighborhood of the Calogero model
Oliver Haschke, Werner Ruehl
The Hamiltonian of the -particle Calogero model can be expressed in terms of generators of a Lie algebra for a definite class of representations. Maintaining this Lie algebra, i…
