Abstract: A bstractCalogero-Sutherland models of N identical particles on a circle are deformed away from hermiticity but retaining a PT$$ \mathcal{P}\mathcal{T} $$ symmetry. The interaction potential gets completely regularized, which adds to the energy spectrum an… read more here.

Abstract: A one-dimensional quantum many-body system consisting of particles confined in a harmonic potential and subject to finite-range two-body and three-body inverse-square interactions is introduced. The range of the interactions is set by truncation beyond a… read more here.

Abstract: Starting from the Hamiltonian formulation of supersymmetric Calogero models associated with the classical $A_n$, $B_n$, $C_n$ and $D_n$ series we construct the ${\cal N}{=}\,2$ and ${\cal N}{=}\,4$ supersymmetric extensions of the their hyperbolic/trigonometric Calogero-Sutherland cousins.… read more here.
