Twisted Boundary Conditions
We explore the N = 1 theories compactified on a circle with twisted boundary conditions. The gauge algebra of these theories are the so-called twisted affine Lie algebra. We propose the exact superpotentials by guessing the sum of all monopole-instanton contributions and also by requiring SL(2, Z) modular properties. The latter is inherited from the N = 4 theory, which will be justified in the ...

متن کاملOn Nahm’s transformation with twisted boundary conditions
Following two different tracks, we arrive at a definition of Nahm’s transformation valid for self-dual fields on the 4-dimensional torus T 4 with non-zero twist tensor. The transform is again a self-dual gauge field defined on a new torus T̂ 4 and with non-zero twist tensor. It preserves the property of being an involution. PACS: 11.15.-q, 11.15.Ha
متن کاملThe gradient flow running coupling with twisted boundary conditions
We study the gradient flow for Yang-Mills theories with twisted boundary conditions. The perturbative behavior of the energy density 〈E(t)〉 is used to define a running coupling at a scale given by the linear size of the finite volume box. We compute the non-perturbative running of the pure gauge SU(2) coupling constant and conclude that the technique is well suited for further applications due ...
متن کاملCasimir force in the rotor model with twisted boundary conditions.
We investigate the three-dimensional lattice XY model with nearest neighbor interaction. The vector order parameter of this system lies on the vertices of a cubic lattice, which is embedded in a system with a film geometry. The orientations of the vectors are fixed at the two opposite sides of the film. The angle between the vectors at the two boundaries is α where 0≤α≤π. We make use of the mea...
