Quantum error correction realized by the renormalization group in scalar field theories
Takaaki Kuwahara, Ryota Nasu, Gota Tanaka +1
We demonstrate that quantum error correction is realized by the renormalization group in scalar field theories. We construct -level states by using coherent states in the IR reg…
Exact renormalization group for wave functionals
Takaaki Kuwahara, Gota Tanaka, Asato Tsuchiya +1
Motivated by the construction of the cMERA for interacting field theories, we derive a non-perturbative functional differential equation for wave functionals in scalar field theori…
Higher derivative extension of the functional renormalization group
Gota Tanaka, Asato Tsuchiya
We study higher derivative extension of the functional renormalization group (FRG). We consider FRG equations for a scalar field that consist of terms with higher functional deriva…
Renormalization group and diffusion equation
Masami Matsumoto, Gota Tanaka, Asato Tsuchiya
We study the relationship between the renormalization group and the diffusion equation. We consider the exact renormalization group equation for a scalar field that includes an arb…
