Applications of the overlap formalism to super Yang-Mills theories
Jun Nishimura
We show that the idea to use the overlap formalism to formulate 4D N=1 super Yang-Mills theory on the lattice without fine-tuning can be applied to 3D N=1 case as well. Another app…
Singular Vertices in the Strong Coupling Phase of Four-Dimensional Simplicial Gravity
T. Hotta, T. Izubuchi, J. Nishimura
We study four-dimensional simplicial gravity through numerical simulation with special attention to the existence of singular vertices, in the strong coupling phase, that are share…
Unitary IIB Matrix Model and the Dynamical Generation of the Space Time
Naofumi Kitsunezaki, Jun Nishimura
We propose a unitary matrix model as a regularization of the IIB matrix model of Ishibashi-Kawai-Kitazawa-Tsuchiya (IKKT). The fermionic part is incorporated using the overlap form…
Lattice Formulation of Supersymmetric Yang-Mills Theories without Fine-Tuning
Nobuhito Maru, Jun Nishimura
We present a lattice formulation which gives super Yang-Mills theories in any dimensions with simple supersymmetry as well as extended supersymmetry in the continuum limit without…
Parity Invariant Lattice Regularization of Three-Dimensional Gauge-Fermion System
Rajamani Narayanan, Jun Nishimura
In three dimensions, the effective action for the gauge field induced by integrating out a massless Dirac fermion is known to give either a parity-invariant or a parity-violating r…
Four-Dimensional N=1 Supersymmetric Yang-Mills Theory on the Lattice without Fine-Tuning
Jun Nishimura
We propose a method to formulate four-dimensional N=1 super Yang-Mills theory on the lattice without fine-tuning. We first show that four-dimensional Weyl fermion in a real represe…
