Unconstrained Variables and Equivalence Relations for Lattice Gauge Theories
Unconstrained Variables Equivalence Relations Lattice Gauge Theories
2010/12/27
We write the partition function for a lattice gauge theory exactly in terms of unconstrained variables and show that in the calculation for the effective potential, which involves uniform field config...
Domain Wall Fermion Lattice Simulation in Quaternion Basis
Domain Wall Fermion Lattice Simulation Quaternion Basis
2011/1/7
In the QCD analysis, when quarks are expressed in quaternion basis, the quark and its charge conjugate together are expressed by octonions and the octonion posesses the triality symmetry. Gluos are ex...
Species Doublers as Super Multiplet Partners in Lattice Supersymmetry
Species Doublers Super Multiplet Partners
2011/1/6
We propose a new lattice superfield formalism in momentum representation which accommodates species doublers of the lattice fermions and their bosonic counterparts as super multiplets. We explicitly s...
I propose a method for measuring the Witten index using a lattice simulation. The index is useful to discuss spontaneous breaking of supersymmetry. As a test of the method, I also report some numerica...
合肥光源高亮度模式Lattice设计
高亮度 低发射度 Lattice 储存环
2009/7/29
介绍了一组合肥光源新高亮度模式的Lattice. 新的设计维持了储存环上所有元件和光束线位置不变,也没有加入新的元件. 取得了较低发射度. 所有直线节处的垂直方向β函数值都很小，适合插入件的运行. 跟踪计算表明新Lattice具有足够大的动力学孔径用于注入和储存粒子.
