Coherent state path integrals in the continuum

Understand

We discuss the time-continuous path integration in the coherent states basis in a way that is free from inconsistencies.

• Employing this notion we reproduce known and exact results working directly in the continuum.
• Such a formalism can set the basis to develop perturbative and non-perturbative approximations already known in the quantum field theory community.
• These techniques can be proven useful in a great variety of problems where bosonic Hamiltonians are used.
