Dynamical frictional phenomena in an incommensurate two-chain model
Takaaki Kawaguchi, Hiroshi Matsukawa
Dynamical frictional phenomena are studied theoretically in a two-chain model with incommensurate structure. A perturbation theory with respect to the interchain interaction reveal…
Algebraic Structure in Non-Orientable Open-Closed String Field Theories
Naohito Nakazawa, Daiji Ennyu
We apply stochastic quantization method to real symmetric matrix-vector models for the second quantization of non-orientable strings, including both open and closed strings. The Fo…
Static and dynamic properties of frictional phenomena in a one-dimensional system with randomness
Takaaki Kawaguchi, Hiroshi Matsukawa
Static and dynamic frictional phenomena at the interface with random impurities are investigated in a two-chain model with incommensurate structure. Static frictional force is caus…
Spin and Charge Structure Factor of the 2-d Hubbard Model
Walter Zimmermann, Raymond Fresard, Peter Woelfle
The spin and charge structure factors are calculated for the Hubbard model on the square lattice near half-filling using a spin-rotation invariant six-slave boson representation. T…
