SUMMARY:Pilot-wave theory and quantum fields - Ward Struyve (KU Leuven)
DTSTART:20120315T141500Z

DESCRIPTION:I will present an overview of possible extensions of the de Br
 oglie-Bohm pilot-wave theory to quantum field theory. In such approaches\,
  systems are not only described by their wave function\, as in standard qu
 antum theory\, but also by some additional variables. In the non-relativis
 tic pilot-wave theory of de Broglie and Bohm these variables are particle 
 positions. In the context of quantum field theory\, a number of approaches
  seem possible. I will discuss approaches with particle positions and with
  field configurations as additional variables. I will also consider the st
 atus of Lorentz invariance in these models. While they are Lorentz invaria
 nt at the empirical level (in quantum equilibrium)\, Lorentz invariance is
  violated at the fundamental level. I will present a way to achieve Lorent
 z invariance also at the fundamental level.
