A perturbative approach to the quantum elliptic Calogero-Sutherland model

Jose Fernandez Nunez, Wifredo Garcia Fuertes, Askold Perelomov

We solve perturbatively the quantum elliptic Calogero-Sutherland model in the regime in which the quotient between the real and imaginary semiperiods of the Weierstrass $\mathcal{P}$…
