Tensor-network approach to thermalization in open quantum many-body systems
Hayate Nakano, Tatsuhiko Shirai, Takashi Mori
We investigate the relaxation dynamics of open non-integrable quantum many-body systems in the thermodynamic limit by using a tensor-network formalism. We simulate the Lindblad qua…
Improved generalization by noise enhancement
Takashi Mori, Masahito Ueda
Recent studies have demonstrated that noise in stochastic gradient descent (SGD) is closely related to generalization: A larger SGD noise, if not too large, results in better gener…
Resolving Discrepancy between Liouvillian Gap and Relaxation Time in Boundary-Dissipated Quantum Many-Body Systems
Takashi Mori, Tatsuhiko Shirai
The gap of the Liouvillian spectrum gives the asymptotic decay rate of a quantum dissipative system, and therefore its inverse has been identified as the slowest relaxation time. I…
Is deeper better? It depends on locality of relevant features
Takashi Mori, Masahito Ueda
It has been recognized that a heavily overparameterized artificial neural network exhibits surprisingly good generalization performance in various machine-learning tasks. Recent th…
