Estimates of ground state energies for the quantum SK and 2D-EA models, using deGennes-Suzuki-Kubo mean-field annealing dynamics
Soumyaditya Das, Soumyajyoti Biswas, Bikas K. Chakrabarti
We perform large scale quantum annealing of the Sherrington-Kirkpatrick (SK) spin glass up to a system size to estimate its ground state energy using the deGennes-Suzuki-…
Exponent spectrum of Lorenz curves and its relation to system's heterogeneity
Soumyaditya Das, Soumyajyoti Biswas
We analyze the effect of microscopic heterogeneity on the Lorenz curve of macroscopic observables. Lorenz curve of a response function being a cumulative and bounded quantity, is o…
Spin Glass Mapping of the Parallel Minority Game
Aryan Tyagi, Soumyaditya Das, Soumyajyoti Biswas +1
The parallel minority game (PMG) extends the classical minority game to many choices, with each agent restricted to two predetermined alternatives. In this condition, minimizing th…
deGennes-Suzuki-Kubo Quantum Ising Mean Field Dynamics: Applications to Quantum Hysteresis, Heat Engines and Annealing
Soumyaditya Das, Soumyajyoti Biswas, Muktish Acharyya +1
We briefly review the early development of the mean-field dynamics for cooperatively interacting quantum many-body systems, mapped to pseudo-spin (Ising-like) systems. We start wit…
Quantum Annealing in SK Model Employing Suzuki-Kubo-deGennes Quantum Ising Mean Field Dynamics
Soumyaditya Das, Soumyajyoti Biswas, Bikas K. Chakrabarti
We study a quantum annealing approach for estimating the ground state energy of the Sherrington-Kirpatrick mean field spin glass model using the Suzuki-Kubo-deGennes dynamics appli…
Classical Annealing of Sherrington-Kirkpatrick Spin Glass Using Suzuki-Kubo Mean-field Ising Dynamics
Soumyaditya Das, Soumyajyoti Biswas, Bikas K. Chakrabarti
We propose and demonstrate numerically a fast classical annealing scheme for the Sherrington-Kirkpatrick (SK) spin glass model, employing the Suzuki-Kubo meanfield Ising dynamics (…
