Exactness of the replica method in perturbation
Hisamitsu Mukaida, Yoshinori Sakamoto
The replica method for a quenched disordered system is considered in a perturbative field theory. Since correction in a finite-order perturbation is given in a polynomial of the re…
Comment on ``Random-Field Spin Model beyond 1 Loop: A Mechanism for Decreasing the Lower Critical Dimension"
Yoshinori Sakamoto, Hisamitsu Mukaida, Chigak Itoi
A comment on the Letter by Le Doussal and Wiese, Phys. Rev. Lett. 96, 197202 (2006).
Stability of fixed points in the (4+ε)-dimensional random field O(N) spin model for sufficiently large N
Yoshinori Sakamoto, Hisamitsu Mukaida, Chigak Itoi
We study the stability of fixed points in the two-loop renormalization group for the random field O() spin model in dimensions. We solve the fixed-point equation in the 1/…
Random field O(N) spin model near four dimensions
Chigak Itoi, Hisamitsu Mukaida, Yoshinori Sakamoto
This paper has been withdrawn by the authors, due to a crucial error in beta functions.
