Abstract

We study super Yang-Mills (SYM) theory on with the 't Hooft twist. The theory becomes weakly coupled if the length of is sufficiently small, . We explore the nonperturbative dynamics at the weak-coupling regime by changing the size of and uncover how d monopole/bion-based effective theory for is related to the d vortex-based theory for . The highlights of our results are (1) the smooth "weak-weak" continuity of the vacuum structure and gluino condensate during the d-d dimensional reduction, (2) the switching of Wilson loop behavior from the area law in d to the perimeter law in d via a "double-string" picture, (3) the role of mass deformation in breaking discrete chiral symmetry and restoring the area law in d, and (4) the microscopic investigation of bions during the reduction from d to d and the cancellation of the vacuum energy due to the hidden topological angle. We also discuss the generalization of our results for (1)--(3) from SYM to QCD with adjoint quarks.
