In particular, we study energy transfer and equilibration processes among the gauge and Higgs sectors, calculate the maximal Liapunov exponents regarding to random initial conditions in the regime of weak coupling, where one expects them to be related to the high-temperature static plasmon damping rate, and investigate their energy and Higgs self-coupling parameter dependence. We further examine finite-time and finite-size errors, value the impact of the Higgs fields on the instabilty of constant non-abelian magnetic fields and comment on the implications of our obtained results for the thermalization properties of gauge fields at finite temperature in the presence of matter.

We apply the Quantum Inverse Scattering approach to a class of three-state vertex model with both closed and open boundaries. The respective transfer matrices eigenvalues and eigenvectors are determined by the algebraic Bethe ansatz method. / Nesta dissertação descrevemos primeiramente os conceitos e técnicas matemáticas relevantes a teoria dos modelos integráveis bidimensionais. O formalismo do Método do Espalhamento Inverso Quântico é aplicado a um modelo de vértices assimétricos de três estados com condições de contorno fechado e aberto. Determinamos então os autovalores e autovetores das respectivas matrizes de transferência pelo método do ansatz de Bethe algébrico.

This paper focuses on comparison of two memoirs from different periods of Chinese history: Shěn Fù's Six Chapters of a Floating Life (turn of 18th and 19th century) and Yáng Jiàng's Six Chapters from a Cadre School (first published in 1981). Both memoirs are joined in intertextual relationship; Yáng Jiàng refers to Shěn Fù's text by both title and structure of her work, while Qián Zhōngshū, her well-known husband, presents in his preface Six Chapters of a Floating Life as a book he never liked. This paper examines message of these two memoirs by formal and thematic analysis of topics, genre characteristics and attitude toward life of both authors.

The ancient Chinese I Ching, the Book of Changes, and the philosophy of the German philosopher Friedrich Nietzsche (1844-1900) both assert that the universe exists in a state of change. The I Ching, originally a book of divination, illustrates the changing phenomena of the natural world in terms of sixty-four hexagrams, which are figures composed of six lines  yielding and firm lines, representing actual conditions and relationships existing in the world and caused by the interplay between two primordial forces, yin and yang. The I Ching shows that on the macro level the Tao works in the universe, in heaven and on earth, and on the micro level it applies to man. The I Ching teaches harmony with Tao and its power (natural law and moral law), so that its reader may take appropriate action in any given situation with reference to the hexagrams and their appended judgments as revealed by the oracle. Nietzsche, however, regards the world as the Will to Power, ‘a monster of energy’, like a storming and flooding ocean eternally changing, where harmony and order seems impossible. His mouthpiece, Zarathustra, who teaches the Übermensch, encourages a war-like attitude towards life. Zarathustra’s second metamorphosis of an evolving spirit, the warrior lion, marks the difference between the Nietzschean Übermensch and the Chinese sage who attains harmony and balance within and without, a mysterious union with heaven. Zarathustra’s third metamorphosis, a playing child, creates itself as its own ‘bridge’ through a process of self-overcoming, whereas the I Ching indicates order to be the ‘bridge’ over chaos, the order of the human world being expressed in the five cardinal relationships. Whereas the I Ching advises its reader to follow their own nature and fate in order to lead a harmonious moral life, Nietzsche’s Übermensch is ‘the annihilator of morality’ and paradoxically ‘the designation of a type of supreme achievement’ (EH Books 1). With his idea of the Übermensch, Nietzsche indicates that morality is a pose (BGE 216). He seeks to make us become aware that we should invent our own virtue and create our own way in order to become what we are. He criticizes Christian morality, calling himself ‘the first immoralist’. His shocking approach attempts to make us become aware of the possibility that a ‘noble morality’ and ‘higher moralities’ ought to be possible. His Übermensch represents such a higher mode of existence. Zarathustra also teaches the doctrine of eternal recurrence, implying that moment is eternity, changelessness within change. Multifarious manifestations are the expression of the Tao. Everything is interconnected and interdependent. Whereas ordinary men see the continuity of phenomena as real, enlightened beings are aware of the transitory and illusive nature of the self and all things. The Nietzschean Übermensch embodies the characteristics of an enlightened being, a Buddha or Bodhisattva in Buddhist terms, characteristics such as wisdom and compassion. Therefore, the practice of the Bodhisattva is explored as a feasible way for actualizing the Nietzschean hypothetical Übermensch. / Thesis (DPhil)--University of Pretoria, 2009. / Philosophy / unrestricted

Supersymmetrische Feldtheorien können durch eine nicht-lineare und nicht-lokale Transformation der bosonischen Felder charakterisiert werden, der Nicolai-Abbildung. Sie bildet das wechselwirkende Funktionalmaß so auf das Maß der zugehörigen freien Theorie ab, dass die Jacobi-Determinante gleich dem Produkt der fermionischen Determinanten ist. Wir untersuchen die Nicolai-Abbildungen des 2-dimenionalen Wess-Zumino Modells und der N=1 sowie N=4 super Yang-Mills Theorien. Wir geben einen konstruktiven Beweis für die Existenz der Nicolai-Abbildung in diesen Theorien. Der Beweis beinhaltet die Herleitung des infinitesimalen Generators der inversen Abbildung, dem R-Operator. Wir benutzen diesen Operator, um die Nicolai-Abbildung im 2-dimensionalen Wess-Zumino Modell bis zur fünften Ordnung in der Kopplung zu berechnen. In der N=1 super Yang-Mills Theorie führen wir die Begriffe der on- bzw. off-shell Nicolai-Abbildungen ein. Die on-shell Abbildung existiert in d=3,4,6 und 10 Dimensionen aber nur für die Landau Eichung. Wir bestimmen sie bis zur vierten Ordnung. Die off-shell Abbildung existiert nur in d=4 Dimensionen aber für allgemeine Eichungen. Wir berechnen sie in der axialen Eichung bis zur zweiten Ordnung. Für die N=4 super Yang-Mills Theorie geben wir den R-Operator an und zeigen, dass man die N=4 Nicolai-Abbildung durch dimensionale Reduktion aus der N=1 Abbildung erhält. Inverse Nicolai-Abbildungen bilden Quantenkorrelationsfunktionen bosonischer Observablen auf freie Korrelationsfunktionen ab. Daher gestatten sie eine Quantisierung supersymmetrischer Theorien ohne die Verwendung von Fermionen oder Geistern. Wir benutzten diese Eigenschaft, um den Vakuum-Erwartungswert der Maldacena-Wilson Geraden bis zur sechsten Ordnung zu berechnen. Im zweiten Teil dieser Arbeit bestimmen wir die explizite Form aller Felder im 1/2-BPS Energie-Impuls-Tensor Multiplet in N=4 super Yang-Mills. Dieses Multiplet enthält den R-Symmetrie Fluss und den Energie-Impuls-Tensor. / Supersymmetric field theories can be characterized by the existence of a non-linear and non-local transformation of the bosonic fields, the Nicolai map. It maps the interacting functional measure to that of a free theory such that the Jacobian determinant of the transformation equals the product of the fermionic determinants. In this thesis, we study the Nicolai maps of the 2-dimensional Wess-Zumino model, N=1 super Yang-Mills and N=4 super Yang-Mills. We give a constructive proof for the existence of the Nicolai map in these theories. The proof includes the derivation of the infinitesimal generator of the inverse Nicolai map, called the R-operator. We use this operator to compute the Nicolai map of the 2-dimensional Wess-Zumino model up to the fifth order in the coupling. In N=1 super Yang-Mills, we introduce the notion of on- and off-shell Nicolai maps. The on-shell Nicolai map of N=1 super Yang-Mills exists in d=3,4,6 and 10 dimensions but is constrained to the Landau gauge. We compute this map up to the fourth order. The off-shell Nicolai map exists only in d=4 dimensions but for general gauges. We compute it in the axial gauge up to the second order. In N=4 super Yang-Mills, we give the R-operator and show that the Nicolai map can be obtained from the Nicolai map of 10-dimensional N=1 super Yang-Mills by dimensional reduction. Inverse Nicolai maps map quantum correlation functions of bosonic observables to free correlation functions. Hence, Nicolai maps allow for a fermion (and ghost) free quantization of supersymmetric (gauge) theories. We apply this property to compute the vacuum expectation value of the infinite straight line Maldacena-Wilson loop in N=4 super Yang-Mills to the sixth order. Thus extending the previous perturbative result by one order. In the second part of this thesis, we derive the explicit field content of the 1/2-BPS stress tensor multiplet in N=4 super Yang-Mills, which contains the R-symmetry current and the energy-momentum tensor.
