The FZZ duality with boundary
Thomas Creutzig, Yasuaki Hikida, Peter B. Ronne
The Fateev-Zamolodchikov-Zamolodchikov (FZZ) duality relates Witten's cigar model to sine-Liouville theory. This duality was proven in the path integral formulation and extended to…
Non-Abelian Monopoles in the Higgs Phase
Muneto Nitta, Walter Vinci
We use the moduli matrix approach to study the moduli space of 1/4 BPS kinks supported by vortices in the Higgs phase of N = 2 supersymmetric U(N) gauge theories when non-zero mass…
Nonperturbative studies of supersymmetric matrix quantum mechanics with 4 and 8 supercharges at finite temperature
Masanori Hanada, So Matsuura, Jun Nishimura +1
We investigate thermodynamic properties of one-dimensional U(N) supersymmetric gauge theories with 4 and 8 supercharges in the planar large-N limit by Monte Carlo calculations. Unl…
Group Theory of Non-Abelian Vortices
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +4
We investigate the structure of the moduli space of multiple BPS non-Abelian vortices in U(N) gauge theory with N fundamental Higgs fields, focusing our attention on the action of…
Six-point gluon scattering amplitudes from Z_4-symmetric integrable model
Yasuyuki Hatsuda, Katsushi Ito, Kazuhiro Sakai +1
We study six-point gluon scattering amplitudes in N=4 super Yang-Mills theory at strong coupling by investigating the thermodynamic Bethe ansatz equations of the underlying Z_4-sym…
Branes in the OSP(1|2) WZNW model
Thomas Creutzig, Yasuaki Hikida
The boundary OSP(1|2) WZNW model possesses two types of branes, which are localized on supersymmetric Euclidean AdS and on two-dimensional superspheres. We compute the coupling…
