Distribution of Lee-Yang zeros and Griffiths singularities in the model of spin glasses
Yoshiki Matsuda, Hidetoshi Nishimori, Koji Hukushima
We investigate the distribution of zeros of the partition function of the two- and three-dimensional symmetric Ising spin glasses on the complex field plane. We use the met…
Inequalities for the Local Energy of Random Ising Models
Hidetsugu Kitatani, Hidetoshi Nishimori, Akira Aoki
We derive a rigorous lower bound on the average local energy for the Ising model with quenched randomness. The result is that the lower bound is given by the average local energy c…
Quantum annealing of the random-field Ising model by transverse ferromagnetic interactions
Sei Suzuki, Hidetoshi Nishimori, Masuo Suzuki
We introduce transverse ferromagnetic interactions, in addition to a simple transverse field, to quantum annealing of the random-field Ising model to accelerate convergence toward…
Convergence of Quantum Annealing with Real-Time Schrodinger Dynamics
Satoshi Morita, Hidetoshi Nishimori
Convergence conditions for quantum annealing are derived for optimization problems represented by the Ising model of a general form. Quantum fluctuations are introduced as a transv…
