Particle-number conservation in thermodynamic systems within the Richardson model

Particle Number Conservation in Tiie Massive Thirring Model

We computed parr-production and nontrivlal three-particle scattering amphtudes of the massive Thirring model in one loop approximation. They are found to be zero. In contrast to the massless Thirring model in the massive Thirring model an explicit solution is unknown. Methods [1] useful in the massless case cannot be applied because the axial current is not conserved. Moreover the S-matrix deri...

heterogeneity 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...

Role of particle conservation in self-propelled particle systems

Actively propelled particles undergoing dissipative collisions are known to develop a state of spatially distributed coherently moving clusters. For densities larger than a characteristic value, clusters grow in time and form a stationary well-ordered state of coherent macroscopic motion. In this work we address two questions. (i) What is the role of the particles’ aspect ratio in the context o...

Localization of shocks in driven diffusive systems without particle number conservation.

We study the formation of localized shocks in one-dimensional driven diffusive systems with spatially homogeneous creation and annihilation of particles (Langmuir kinetics). We show how to obtain hydrodynamic equations that describe the density profile in systems with uncorrelated steady state as well as in those exhibiting correlations. As a special example of the latter case, the Katz-Lebowit...
