    • B-branes and supersymmetric quivers in 2d 

      Closset, Cyril; Guo, Jirui; Sharpe, Eric R. (Springer, 2018-02-08)
      We study 2d N = (0, 2) supersymmetric quiver gauge theories that describe the low-energy dynamics of D1-branes at Calabi-Yau fourfold (CY4) singularities. On general grounds, the holomorphic sector of these theories - ...
    • D-particles on orientifolds and rational invariants 

      Lee, Seung-Joo; Yi, Piljin (Springer, 2017-07-11)
      We revisit the DO bound state problems, of the M/IIA duality, with the Orientifolds. The cases of 04 and 08 have been studied recently, from the perspective of five-dimensional theories, while the case of O0 has been much ...
    • Witten index for noncompact dynamics 

      Lee, Seung-Joo; Yi, Piljin (Springer, 2016-06-16)
      Among gauged dynamics motivated by string theory, we find many with gapless asymptotic directions. Although the natural boundary condition for ground states is L-2, one often turns on chemical potentials or supersymmetric ...
