Query: Quantum dissipation in a scalar field theory with gapped momentum states   Understanding quantum dissipation is important from both theoretical
perspective and applications. Here, we show how to describe dissipation in a
scalar field theory. We treat dissipation non-perturbatively, represent it by a
bilinear term in the Lagrangian and quantize the theory. We find that
dissipation promotes a gap in momentum space and reduces the particle energy.
As a result, particle mass becomes dressed by dissipation due to
self-interaction. The underlying mechanism is similar to that governing the
propagation of transverse collective modes in liquids. We discuss the interplay
between the dissipative and mass terms, the associated different regimes of
field dynamics and the emergence of ultraviolet and infrared cutoffs due to
dissipation.
