Welcome to the Department of Physics.
A very intense force field can break down the bosonic vacuum and create boson-antiboson pairs. We have extended our theoretical framework of computational quantum field theory to deal with this situation by solving the Klein-Gordon equation instead of the Dirac equation. In order to make a direct comparison between the boson and fermion pair creation, we have used the Feshbach-Villars form for the K-G equation.
