Path Integral Representation for Weyl Particle Propagator
We present a path integral representation for massless spin one-half particles. It is shown that this gives us a super–symmetric, P − and T −non–invariant pseudoclassical model for relativistic massless spinning particles. Dirac quantization of this model is considered.
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
The Semiclassical Propagator in Fermionic Fock Space
We present a rigorous derivation of a semiclassical propagator for anticommuting (fermionic) degrees of freedom, starting from an exact representation in terms of Grassmann variables. As a key feature of our approach the anticommuting variables are integrated out exactly, and an exact path integral representation of the fermionic propagator in terms of commuting variables is constructed. Since ...
متن کاملA quantum propagator for path-integral simulations of rigid molecules.
The expression for the quantum propagator for rigid tops, proposed by Müser and Berne [Phys. Rev. Lett. 77, 2638 (1996)], has been extended to asymmetric tops. Path-integral Monte Carlo simulations are provided that show that the quantum propagator proposed in this work exactly reproduces the rotational energy of free asymmetric tops as evaluated from the partition function. This propagator can...
