High-dimensional theory of the glass transition revisited: hopping and local defects
Harukuni Ikeda, Francesco Zamponi
The replicated liquid theory provides a microscopic mean-field description of the glass transition by combining the density functional theory of liquids with the replica method ori…
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 …
Mean-field caging in a random Lorentz gas
Giulio Biroli, Patrick Charbonneau, Yi Hu +3
The random Lorentz gas (RLG) is a minimal model of both percolation and glassiness, which leads to a paradox in the infinite-dimensional, limit: the localizati…
Finite size effects in the microscopic critical properties of jammed configurations: A comprehensive study of the effects of different types of disorder
Patrick Charbonneau, Eric I. Corwin, R. Cameron Dennis +4
Jamming criticality defines a universality class that includes systems as diverse as glasses, colloids, foams, amorphous solids, constraint satisfaction problems, neural networks,…
Vibrational density of states of jammed packing: mean-field theory
Harukuni Ikeda, Masanari Shimada
Several mean-field theories predict that Hessian matrices of amorphous solids can be written by using the random matrix in the limit of the large spatial dimensions . M…
Force balance controls the relaxation time of the gradient descent algorithm in the satisfiable phase
Sungmin Hwang, Harukuni Ikeda
We numerically study the relaxation dynamics of the single layer perceptron with the spherical constraint. This is the simplest model of neural networks and serves a prototypical m…
Mean field theory of jamming of nonspherical particles
Harukuni Ikeda, Pierfrancesco Urbani, Francesco Zamponi
Recent computer simulations have uncovered the striking difference between the jamming transition of spherical and non-spherical particles. While systems of spherical particles are…
Note: Effect of localization on mean-field density of state near jamming
Harukuni Ikeda
We discuss the effects of the localized modes on the density of state by introducing the probability distribution function of the proximity to the marginal stability. Our th…
Universality of jamming of non-spherical particles
Carolina Brito, Harukuni Ikeda, Pierfrancesco Urbani +2
Amorphous packings of non-spherical particles such as ellipsoids and spherocylinders are known to be hypostatic: the number of mechanical contacts between particles is smaller than…
Mean field theory of the swap Monte Carlo algorithm
Harukuni Ikeda, Francesco Zamponi, Atsushi Ikeda
The swap Monte Carlo algorithm combines the translational motion with the exchange of particle species, and is unprecedentedly efficient for some models of glass former. In order t…
The Fredrickson-Andersen model with random pinning on Bethe lattices and its MCT transitions
Harukuni Ikeda, Kunimasa Miyazaki, Giulio Biroli
We investigate the dynamics of the randomly pinned Fredrickson-Andersen model on the Bethe lattice. We find a line of random pinning dynamical transitions whose dynamical critical…
The decoupling of the glass transitions in the two-component -spin spherical model
Harukuni Ikeda, Atsushi Ikeda
Binary mixtures of large and small particles with disparate size ratio exhibit a rich phenomenology at their glass transition points. In order to gain insights on such systems, we…
Fredrickson-Andersen model on Bethe lattice with random pinning
Harukuni Ikeda, Kunimasa Miyazaki
We study the effects of random pinning on the Fredrickson-Andersen model on the Bethe lattice. We find that the nonergodic transition temperature rises as the fraction of the pinne…
