All-mode Renormalization for Tensor Network with Stochastic Noise

Erika Arai, Hiroshi Ohki, Shinji Takeda +1

In usual (non-stochastic) tensor network calculations, the truncated singular value decomposition (SVD) is often used for approximating a tensor, and it causes systematic errors. B…

Discovering new physics in rare kaon decays

Thomas Blum, Peter Boyle, Mattia Bruno +20

The decays and mixing of mesons are remarkably sensitive to the weak interactions of quarks and leptons at high energies. They provide important tests of the standard model at…

Hybrid stochastic method for the tensor renormalization group

Hiroshi Ohki, Erika Arai, Masaaki Tomii

We propose a hybrid stochastic method for the tensor renormalization group (TRG) approach. TRG is known as a powerful tool to study the many-body systems and quantum field theory o…

Towards non-perturbative matching of three/four-flavor Wilson coefficients with a position-space procedure

Masaaki Tomii

We propose a strategy to non-perturbatively match the Wilson coefficients in the three- and four-flavor theories, which uses two-point Green's functions of the corresponding four-q…

-symmetric position-space renormalization of lattice operators

Masaaki Tomii, Norman H. Christ

We extend the position-space renormalization procedure, where renormalization factors are calculated from Green's functions in position space, by introducing a technique to take th…
