Topological Quantum Field Theories for Surfaces with Spin Structure
نویسندگان
چکیده
Reened quantum invariants for closed three-manifolds with links and spin structures are extended to a Topological Quantum Field Theory. By a `universal con-struction', one associates, to surfaces with structure, modules which are shown to be free of nite rank. These modules satisfy the multiplicativity axiom of TQFT in an extended Z=2-graded sense, and their ranks are given by a spin reened version of thèVerlinde formula'. The relationship with thèunspun' theory is given by a naturaìtransfer map'.

Spin Topological Quantum Field Theories
Starting from the quantum group Uq(sl(2, C)), we construct operator invariants of 3-cobordisms with spin structure, satisfying the requirements of a topological quantum field theory and refining the Reshetikhin–Turaev and Turaev–Viro models. We establish the relationship between these two refined models.
متن کاملEquivariant Localization of Path Integrals
We review equivariant localization techniques for the evaluation of Feynman path integrals. We develop systematic geometric methods for studying the semi-classical properties of phase space path integrals for dynamical systems, emphasizing the relations with integrable and topological quantum field theories. Beginning with a detailed review of the relevant mathematical background – equivariant ...
متن کاملSpin network setting of topological quantum computation
The spin network simulator model represents a bridge between (generalised) circuit schemes for standard quantum computation and approaches based on notions from Topological Quantum Field Theories (TQFTs). The key tool is provided by the fiber space structure underlying the model which exhibits combinatorial properties closely related to SU(2) state sum models, widely employed in discretizing TQ...
متن کاملA class of P ; T - invariant topological phases of interacting electrons
We describe a class of parityand time-reversal-invariant topological states of matter which can arise in correlated electron systems in 2+1-dimensions. These states are characterized by particle-like excitations exhibiting exotic braiding statistics. P and T invariance are maintained by a doubling of the low-energy degrees of freedom which occurs naturally without doubling the underlying micros...
