Lefschetz Thimbles and Quantum Phases in Zero-Dimensional Bosonic Models

10 Feb 2020  ·  Bharathkumar R., Joseph Anosh ·

In this paper, by analyzing the underlying Lefschetz thimble structure, we study quantum phases in zero-dimensional scalar field theories with complex actions. Using first principles, we derive the Lefschetz thimble equations of these models, and discuss the issues when we apply the same calculations for more complicated systems... We also derive the conditional expressions involving relations among the parameters of the model, that would help us predict quantum phase transitions in these systems. read more
