Supersymmetric theories on the lattice by Sergey Alexandrovich Karamov( )

2 editions published in 2003 in English and held by 1 WorldCat member library worldwide

Both theoretical and computational aspects involved in non-perturbative studies of supersymmetric field theories are discussed. Specifically this thesis focuses on Wess-Zumino models in one and two dimensions. In two of the three models considered a lattice action which preserves an exact supersymmetry may be derived. In the third case no such action is possible, nevertheless a lattice theory can be written down which preserves supersymmetry at the quantum level to all orders in perturbation theory in the limit of vanishing lattice spacing. Dynamical fermion simulations are carried out using improved algorithms for all these models and the numerical results for mass spectra and Ward identities compared with theoretical expectations. For the third case evidence for spontaneous supersymmetry breaking via tunneling effects in finite volumes is presented

Mr Pops and and Bozo are two dogs who just love playing with balls. Perhaps you did not know there were so many different ways to play with balls. Join them as they play all day with their favourite toy in a variety of places using a variety of actions

Exact lattice supersymmetry by Simon Catterall( Book )

1 edition published in 2009 in English and held by 1 WorldCat member library worldwide

We provide an introduction to recent lattice formulations of supersymmetric theories which are invariant under one or more real supersymmetries at nonzero lattice spacing. These include the especially interesting case of N = 4 SYM in four dimensions. We discuss approaches based both on twisted supersymmetry and orbifold-deconstruction techniques and show their equivalence in the case of gauge theories. The presence of an exact supersymmetry reduces and in some cases eliminates the need for fine tuning to achieve a continuum limit invariant under the full supersymmetry of the target theory. We discuss open problems

Critical behavior of spin models on fluctuating bounded geometries by Scott Vincent McGuire( )

1 edition published in 2001 in English and held by 0 WorldCat member libraries worldwide

This dissertation describes the use of Monte Carlo simulations to study systems consisting of simple matter fields coupled to 2-d quantum gravity. Explicitly, we have studied Ising spins in interaction with a discrete triangulated geometry with the topology of a disk. Two classes of lattice model were examined; in the first the Ising spins were placed on the vertices of the triangulation and in the second they were associated with centers of triangles. In both cases we have utilized an Ising action which contains a boundary magnetic field. For the case of Ising spins on the vertices and zero boundary magnetic field, it is shown that the model possesses three phases. For one of these the boundary length grows linearly with disk area while the other two phases are characterized by a boundary length on the order of the cut-off. A line of continuous magnetic transitions separates the two small boundary phases. The critical exponents of the continuous magnetic phase transition are determined and related to predictions from continuum 2-d quantum gravity. This line of continuous transitions terminates on a line of discontinuous phase transitions dividing the small boundary phases from the large boundary phase. The scaling of bulk magnetization and boundary magnetization as a function of boundary magnetic field in the vicinity of this tricritical point are examined. The corresponding tricritical point for the model with Ising spins on the triangles is found. The scaling of bulk magnetization and boundary magnetization as a function of boundary magnetic field in the vicinity of this tricritical point are examined as well. We discuss the results in the context of universality of lattice models
