A Lie-Algebraic Approach To the Kondo Problem
S. G. Rajeev
The Kondo problem is studied using the unitary Lie algebra of spin-singlet fermion bilinears. In the limit when the number of values of the spin goes to infinity the theory app…
The Maxwell-Boltzmann Distribution is not the Equilibrium on a Hyperboloid
S. G. Rajeev
We give a geometric formulation of the Fokker-Planck-Kramer equations for a particle moving on a Lie algebra under the influence of a dissipative and a random force. Special cases…
Geometry of the Motion of Ideal Fluids and Rigid Bodies
S. G. Rajeev
Arnold pointed out that the Euler equation of incompressible ideal hydrodynamics describes geodesics on the group of volume-preserving diffeomorphisms. A simple analogue is the Eul…
Topological Dark Matter in the Little Higgs Models
Anosh Joseph, S. G. Rajeev
We show that certain little Higgs models with symmetry breaking SU(N) -> SO(N) for N >= 4 admit topologically stable solitons that may contribute to cosmological dark matter. We ha…
