The structure of the theory allows us to adjust couplings and interactions with far more freedom than QFT for perturbative purposes.
Among the topics are stochastic dynamics, an oscillator coupled to a harmonic bath, a perturbative approach to exciton relaxation in molecular aggregates, the microscopic theory of linear absorption and fluorescence, and two-dimensional spectroscopy applications for photosynthetic excitons.
Seiberg was named for his unifying quantum field, string and supersymmetric quantum field theories and Witten for non perturbative duality symmetries, models of particle physics derived from string theory, dark matter detection and the twister-string approach to particle scattering amplitudes.
In perturbative QFT, one has to consider Feynman graphs, and to associate to each such a graph a Feynman integral (further related to quantities actually measured in physical experiments).
The main problems in the measurement at the nanoscale are the perturbative effects of the measurement instruments to the nanostructure being investigated.
It was found that full gyrokinetic codes generally predicted higher damping rates than perturbative MHD codes in cases with no continuum damping.
xx](B,T) in GaAs(7) is described well by a perturbative treatment for low-magnetic field [see Ref.
Novel Doubly Nano-Scale Perturbative Resonance Control of a Free-Suspending Photonic Crystal Structure
With the latest progress on the conceptual, theoretical and methodological level the time is ripe to accomplish these challenging goals by establishing novel techniques combining numerical relativity (NR), ``standard~~ perturbative methods and the large-D expansionrecently developed by leading European researchers.
There are formal perturbative approaches to this and some string theory approaches as well.
While strong supporting evidence for the particle physics theory of Quantum Chromodynamics (QCD) has been found in high energy collisions in experimental tests using perturbativetreatments because of its asymptotic freedom behavior, the perturbative procedures have proven problematic for low-energy QCD, since the running coupling constant goes beyond 1.
