Semiclassical Methods in Field Theories: The Use of Soliton and Instanton
The first part of this thesis is to study how solitons interact among themselves in Sine-Gordon system. We translate the information encoded in various known soliton solutions such as scattering time delays and oscillation periods into that of the corresponding quantities in particle dynamics. We …

An optical approximation to the Casimir effect and related topics
… an appropriate hamiltonian I studied it by using semiclassical methods. Some exemplary geometries of interest for the experiments are studied in detail.

Spectral gaps for many-particle systems, semiclassical analysis of graphene, and quantum dynamics
… O(n)-model we use renormalization ideas and semiclassical methods to relate the problem to the study of an auxiliary Schrödinger operator. For the chain of oscillators we map the Fokker-Planck operator to an associated non self-adjoint eigenvalue problem for an auxiliary discrete Schrödinger …

Holographic Superfluids and Solitons
… studying the properties of such solitons using semiclassical methods. This thesis describes an alternative method for the study of superfluid solitons. The method used here is a holographic duality between a class of quantum field theories and gravitational theories. The classical limit of the …

SEMICLASSICAL MOLECULAR DYNAMICS OF ADIABATIC AND NONADIABATIC PROCESSES
… more complicated and computationally daunting. Semiclassical methods are in part able to conciliate the best features of both worlds, allowing for an intuitive description of the underlying nuclear quantum dynamics based on classical molecular dynamics and at the same time keeping the …

Correlated trajectories in semiclassical approaches to quantum chaos
… concerned with the application and extension of semiclassical methods, involving correlated trajectories, that were recently developed to explain the observed universal statistics of classically chaotic quantum systems. First we consider systems that depend on an external parameter that does not …
