Transitions in (1+1) light front Φ<sup>4</sup> theory using quantum computing method

ORAL

Abstract

We study the phase transitions in (1+1) Φ4 theory using discretized light-cone quantization (DLCQ) with both classical computing and quantum computing methods. The transition at the ground state from a single-particle dominant state to a three-particle dominant state can be revealed by the parton distribution function and indicated by crossing of mass square eigenvalues at a strong coupling. The critical coupling is a function of resolution and will be extrapolated to the continuum limit. We discuss quantum computing as a method of exploring quantum phase transition in the light-front (1+1) Φ4 theory.
