283. Quantum kink and its excitations
This is a guest post by Arttu Rajantie from Imperial College. Dmitry.
Dmitry has kindly asked me to write about my recent paper Quantum kink and its excitations, which I wrote with my PhD student David Weir. In it we show how one can obtained detailed information about kinks and other solitons in quantum field theory in a simple way from field correlation functions. What makes this useful is that these correlators can be calculated non-perturbatively using Monte Carlo techniques. We demonstrate the method with kinks in a simple 1+1-dimensional model, but it should be easy to apply it to more realistic theories, leading to a wide range of potential applications.
