(1990)In classical mechanics we divide Hamiltonian systems into integrable and nonintegrable systems. This distinction corresponds to two different kinds of dynamical behavior. The motion of an integrable system is regular and ...

(1971)Protonproton scattering is investigated in a model in which the protons are composed of quarks and the scattering is due to multiple collisions of the quarkso By including spin in the calculation it was hoped that the ...

(1987)KAM theorem is one of the most important theorems in classical nonlinear dynamics and chaos. To extend KAM theorem to the regime of quantum mechanics, we first study the quantum Chirikov map, whose classical counterpart ...

(1973)Several popular field theories are quantized on light fronts, that is O 3 surfaces defined by x + = x0 + x3 = constant. Schwinger's quantum ac tion principle is employed to deduce the correct canonical equalx+(anti) ...

(1999)The quantum kicked rotor has served as a model for testing the ideas of quantum chaos since the field's inception. In this thesis we present an overview of the kicked rotor, both from a semiclassical standpoint as well ...

(1976)In this thesis we consider two aspects of the theory of nonAbelian gauge fields. In the first part,we calculate the fermionfermion scattering amplitude for a nonAbelian gauge theory with SU(N) gauge symmetry in the limit ...

(1978)This thesis contains the descriptions of two new nonperturbative results in relativistic field theory. The first part of the thesis describes a transformation which can be used to relate the strong coupling limit of the ...

(1989)The motion of a charged particle through a magnetic field configuration can be described in terms of deviation from a certain ideal trajectory. One uses power series expansion of the phasespace coordinates to obtain the ...

(1990)This thesis consists of two parts. In the first part we study the dynamics and the boundaries between basins of attraction of a logistic map defined in real 2 x 2 matrices. We show how these boundaries are of a mixed type, ...
