Transient Reserves, Sink Dampers, and the Failure of Eigenvalue Reasoning in the Attention Propagator
Li Hengyu
The attention matrix of a causal transformer is row-stochastic, iterated over depth, and non-normal by construction. For non-normal operators, eigenvalues control only asymptotic b…
Random quantum Ising model with three-spin couplings
Ferenc Iglói, Yu-Cheng Lin
We apply a real-space block renormalization group approach to study the critical properties of the random transverse-field Ising spin chain with multispin interactions. First we re…
Finite-size scaling and dynamics in a two-dimensional lattice of identical oscillators with frustrated couplings
Róbert Juhász, Géza Ódor
A two-dimensional lattice of oscillators with identical (zero) intrinsic frequencies and Kuramoto type of interactions with randomly frustrated couplings is considered. Starting th…
Exact Solution for the Transverse Field Sherrington-Kirkpatrick Spin Glass Model with Continuous-Time Quantum Monte Carlo Method
Annamária Kiss, Gergely Zaránd, Izabella Lovas
We construct the first complete exact numerical solution of a mean field quantum spin glass model, the transverse field Sherrington-Kirkpatrick model, by implementing a continuous-…
Random Ising chain in transverse and longitudinal fields: Strong disorder RG study
Tamás Pető, Ferenc Iglói, István A. Kovács
Motivated by the compound , we consider the Ising chain with random couplings and in the presence of simultaneous random transverse and longitud…
Testing the validity of random-singlet state for long-range hopping models through the scaling of entanglement entropy
Róbert Juhász
We consider a sublattice-symmetric free-fermion model on a one-dimensional lattice with random hopping amplitudes decaying with the distance as , and address the…
