Phase shift analysis of PT-symmetric nonhermitian extension of A_{N-1} Calogero model without confining interaction

B. Basu-Mallick, Tanaya Bhattacharyya, Bhabani Prasad Mandal

We discuss a many-particle quantum system, which is obtained by adding some nonhermitian but PT (i.e. combined parity and time reversal) invariant interaction to the $A_{N-1}$ rati…
