## Key findings

- Establishes a correspondence between excited states and singular vectors.
- Provides explicit examples of singular vectors in Verma modules.
- Develops a free field realization of the time evolution operator.

## Abstract

We present a relationship between the Calogero-Moser particles confined in harmonic oscillator potentials and a representation theory of the infinite dimensional Lie algebra which is a semi-direct sum of Virasoro algebra and its module. More precisely, it is a correspondence of excited states of the model and singular vectors in Verma modules over the algebra. This is found by a free field realization of the time evolution operator of the model. We investigate the Verma modules and some explicit example of singular vectors are given.
