Regularisation as a quantised low-pass filter
L I Plimak
A divergence-free approach to relativistic quantum electrodynamics based on regularisation of equations of quantum mechanics is discussed. This approach is shown to be exactly equi…

Causal signal transmission by quantum fields. II. Quantum-statistical response of interacting bosons
L. I. Plimak, S. Stenholm
We analyse nonperturbatively signal transmission patterns in Green's functions of interacting quantum fields. Quantum field theory is re-formulated in terms of the nonlinear quantu…

Causal signal transmission by quantum fields. I. Response of the harmonic oscillator
L. I. Plimak, S. Stenholm
It is shown that response properties of a quantum harmonic oscillator are in essence those of a classical oscillator, and that, paradoxical as it may be, these classical properties…
