Active Spherical Model
Harukuni Ikeda
The spherical model is a popular solvable model and has been applied to describe several critical phenomena such as the ferromagnetic transition, Bose-Einstein condensation, spin-g…
Universality of classical and quantum SAT-UNSAT transitions of convex continuous satisfaction problems
Harukuni Ikeda
Here we investigate the single-layer linearized perceptron near the SAT-UNSAT transition point as a prototypical model of the convex continuous satisfaction problems. The simplicit…
Bose-Einstein-Like condensation of deformed random matrix: A replica approach
Harukuni Ikeda
In this work, we investigate a symmetric deformed random matrix, which is obtained by perturbing the diagonal elements of the Wigner matrix. The eigenvector …
Control parameter dependence of fluctuation near jamming
Harukuni Ikeda
The fluctuations of the physical quantities play a central role to characterize the critical phenomena. Here, we report that the nature of the fluctuation highly depends on the con…
