Tensor Network Formulation of -Symmetric Quantum Field Theory
Yasuyuki Hatsuda, Kengo Kikuchi
We develop a non-perturbative analytic tensor network formulation of -symmetric scalar field theories defined on complex integration contours. Applying this formulati…
Gradient-flowed order parameter for spontaneous gauge symmetry breaking
Kengo Kikuchi, Kenji Nishiwaki, Kin-ya Oda
The gauge-invariant two-point function of the Higgs field at the same spacetime point can make a natural gauge-invariant order parameter for spontaneous gauge symmetry breaking. Ho…
Perturbative analysis of the Wess-Zumino flow
Daisuke Kadoh, Kengo Kikuchi, Naoya Ukita
We investigate an interacting supersymmetric gradient flow in the Wess-Zumino model. Thanks to the nonrenormalization theorem and an appropriate initial condition, we find that any…
RG flows from WZW models
Ken Kikuchi
We constrain renormalization group flows from type Wess-Zumino-Witten models triggered by adjoint primaries. We propose positive Lagrangian coupling leads to massless flow…
The fate of non-supersymmetric Gross-Neveu-Yukawa fixed point in two dimensions
Yu Nakayama, Ken Kikuchi
We investigate the fate of the non-supersymmetric Gross-Neveu-Yukawa fixed point found by Fei et al in dimensions with a two-component Majorana fermion continued to two dimen…
Emergent symmetry and free energy
Ken Kikuchi
Just as spontaneous symmetry breaking can be understood in terms of energy, emergent symmetry (more precisely, its `size' and structure) can also be explained by free energy. In pa…
