Exactly Solvable Models in Arbitrary Dimensions
Ranjan K. Ghosh, Sumathi Rao
We construct a new class of quasi-exactly solvable many-body Hamiltonians in arbitrary dimensions, whose ground states can have any correlations we choose. Some of the known correl…

MIRROR SYMMETRY IN THE FEW ANYON SPECTRA IN A HARMONIC OSCILLATOR POTENTIAL
Ranjan K. Ghosh, Sumathi Rao
We find that the energy spectra of four and five anyons in a harmonic potential exhibit some mirror symmetric (reflection symmetric about the semionic statistics point ) fea…

Non-linear Field Theory of a Frustrated Heisenberg Spin Chain
Sumathi Rao, Diptiman Sen
We derive a continuum field theory for the Majumdar-Ghosh model in the large- limit, where the field takes values in the manifold of the group. No topological term is in…
