Equivalence of large- gauge theories on a group manifold and its coset space
Kohta Hatakeyama, Asato Tsuchiya
It was shown in arXiv:0912.1456 that the large- reduction holds on group manifolds in the sense that a large- gauge theory on a group manifold is realized by a matrix model w…
MHV amplitudes at strong coupling and linearized TBA equations
Katsushi Ito, Yuji Satoh, Junji Suzuki
The maximally helicity violating (MHV) amplitudes of super Yang-Mills theory at strong coupling are obtained by solving auxiliary thermodynamic Bethe ansatz (TBA) int…
Renormalization on the fuzzy sphere
Kohta Hatakeyama, Asato Tsuchiya, Kazushi Yamashiro
We study renormalization on the fuzzy sphere. We numerically simulate a scalar field theory on it, which is described by a Hermitian matrix model. We show that correlation function…
Toward the construction of the general multi-cut solutions in Chern-Simons Matrix Models
Takeshi Morita, Kento Sugiyama
In our previous work arXiv:1704.08675, we pointed out that various multi-cut solutions exist in the Chern-Simons (CS) matrix models at large- due to a curious structure of the s…
N=(4,0) Super-Liouville Theory on the Coadjoint Orbit and PSU(1,1|2)
Shogo Aoyama
An N=(4,0) supersymmetric Liouville theory is formulated by the coadjoint orbit method. It is discovered that the action has symmetry under PSU(1,1|2).
N=4 Super-Schwarzian Theory on the Coadoint Orbit and PSU(1,1|2)
Shogo Aoyama, Yuco Honda
An N=4 super-Schwarzian theory is formulated by the coadjoint orbit method. It is discovered that the action has symmetry under PSU(1,1|2).
