Multicritical point of spin glasses
Hidetoshi Nishimori, Masayuki Ohzeki
We present a theoretical framework to accurately calculate the location of the multicritical point in the phase diagram of spin glasses. The result shows excellent agreement with n…

Analytical evidence for the absence of spin glass transition on self-dual lattices
Masayuki Ohzeki, Hidetoshi Nishimori
We show strong evidence for the absence of a finite-temperature spin glass transition for the random-bond Ising model on self-dual lattices. The analysis is performed by an applica…

Accuracy thresholds of topological color codes on the hexagonal and square-octagonal lattices
Masayuki Ohzeki
Accuracy thresholds of quantum error correcting codes, which exploit topological properties of systems, defined on two different arrangements of qubits are predicted. We study the…
