1. From there it moves on to particle theory and quantum field theory . 2. This culminated in the formulation of ideas of a quantum field theory . 3. He also researches in beyond standard model physics and quantum field theory . 4. Creator Ocneanu researches mathematical aspects of quantum field theory ( QFT ). 5. In the context of quantum field theory , however, solutions can be found. 6. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory . 7. It is used in quantum mechanics, scattering theory and quantum field theory . 8. In a Quantum Field Theory , a Quantum Fluctuation probes arbitrarily short distances. 9. Under appropriate simplifying assumptions this can be described without quantum field theory . 10. If the quantum field theory can be accurately described through condensates.
