1083“…A real linear combination of the original and added processes leads to a commutation relation analogous to that between a boson field and its canonical momentum in quantum field theory. The resulting pricing formula for a European call option replaces the classical volatility with the norm of a complex quantity, whose imaginary part is shown to compensate for the disparity between prices obtained from the classical Black–Scholes model and actual prices of the test call options. …”

1085por Simioni, Eduard“…Despite its success in describing a large variety of sub-nuclear phenomena, the SM leaves open a number of questions and is regarded by particle physicists as an effective quantum field theory, rather than a credible candidate to be the ultimate theory of fundamental interactions. …”

Magnetic trapping of antihydrogen atoms provides a means of studying them by combining electromagnetic interaction with detection techniques that are unique to antimatter. …”

Zahid“…Moreover, triply-degenerate nodes realize emergent fermionic quasiparticles not present in relativistic quantum field theory. We present materials candidates. Our results open the door for realizing new topological phenomena and fermions including transport anomalies and spectroscopic responses in metallic crystals with nontrivial topology beyond the Weyl/Dirac paradigm.…”

1091por Angelsmark, Martin“…The interaction of the quarks is described by the quantum field theory quantum chromodynamics. Quantum chromodynamics predicts a confinement of the quarks within the hadrons, but at large temperatures and/or energy densities there will be a phase transition from hadrons into a deconfined state called quark gluon plasma. …”

1092por Fagerholm, Erik D., Foulkes, W. M. C., Friston, Karl J., Moran, Rosalyn J., Leech, Robert“…The principle of stationary action is a cornerstone of modern physics, providing a powerful framework for investigating dynamical systems found in classical mechanics through to quantum field theory. However, computational neuroscience, despite its heavy reliance on concepts in physics, is anomalous in this regard as its main equations of motion are not compatible with a Lagrangian formulation and hence with the principle of stationary action. …”
