Large distance expansion in the Schrödinger representation of quantum field theory [PDF]
, 1997 This thesis is concerned with an approach to Quantum Field Theory in which the states are constructed from their large distance behaviour. The logarithm of the vacuum functional is expandable as a local quantity in any quantum field theory in which the ...

Affine toda field theories on a half-line [PDF]
, 1999 This thesis is primarily concerned with the reflection factors of affine Toda field theories on the half-line x ≤ 0. First, we consider the classical background configurations of low rank a,(^(1)) affine Toda theories with a boundary, constructed by the ...

Computation of hybrid static potentials in SU(3) lattice gauge theory
, 2018 We compute hybrid static potentials in SU(3) lattice gauge theory. We present a method to automatically generate a large set of suitable creation operators with defined quantum numbers from elementary building blocks.

Quantum corrections to the classical reflection factor of the sinh-Gordon model [PDF]
, 2000 This thesis studies the quantum reflection factor of the sinh-Gordon model under boundary conditions consistent with integrability. First, we review the affine Toda field theory in Chapter One.

On extended structures in affine Toda field theory [PDF]
, 1996 Two areas of affine Toda field theory are explored in this thesis. First the introduction of a boundary into the real coupling affine Toda field theory.

Effective Field Theories and Quantum Chromodynamics on the Lattice
, 2004 We give a selection of results on spectrum and decay constants of light and heavy-light hadrons. Effective field theories relevant for their lattice calculation, namely non-relativistic QCD (NRQCD) for heavy quarks on the lattice and Chiral Perturbation Theory for light quarks, are briefly discussed.

Tetraquark resonances computed with static lattice QCD potentials and scattering theory
, 2018 We study tetraquark resonances with lattice QCD potentials computed for two static quarks and two dynamical quarks, the Born-Oppenheimer approximation and the emergent wave method of scattering theory.

Unconventional quantum Hall effect and Berry’s phase 2pi in bilayer graphene. [PDF]
, 2006 There are known two distinct types of the integer quantum Hall effect. One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems, and the other is its relativistic counterpart recently observed in graphene ...

Logarithmic corrections in Symanzik’s effective theory of lattice QCD [PDF]
, 2021 Einer der finalen Schritte in Simulationen von Gitter Quantenchromodynamik (QCD) oder Gittereichtheorie ist die Kontinuumsextrapolation, um die eigentliche Kontinuumsphysik zu extrahieren.
