Exact solution of a many body problem with nearest and next-nearest neighbour interactions
B. Basu-Mallick, Anjan Kundu
Recently a partially solvable many-body problem with nearest and next-nearest neighbour interactions is proposed [cond-mat/9904121]. We show that by adding a suitably chosen moment…

Exact solution of Calogero model with competing long-range interactions
B. Basu-Mallick, Anjan Kundu
An integrable extension of the Calogero model is proposed to study the competing effect of momentum dependent long-range interaction over the original ${1 \ov r^2}$ interaction. Th…
