Quantum Circuit Simulation by SGEMM Emulation on Tensor Cores and Automatic Precision Selection
Hiroyuki Ootomo, Hidetaka Manabe, Kenji Harada +1
Quantum circuit simulation provides the foundation for the development of quantum algorithms and the verification of quantum supremacy. Among the various methods for quantum circui…
Quantum critical dynamics in two-dimensional transverse Ising model
Chisa Hotta, Tempei Yoshida, Kenji Harada
In the vicinity of the quantum critical point(QCP), thermodynamic properties diverge toward zero temperature governed by universal exponents. Although this fact is well known, how…
Neural Network Approach to Scaling Analysis of Critical Phenomena
Ryosuke Yoneda, Kenji Harada
Determining the universality class of a system exhibiting critical phenomena is one of the central problems in physics. There are several methods to determine this universality cla…
Universal spectrum structure at nonequilibrium critical points in the (1+1)-dimensional directed percolation
Kenji Harada
Using a tensor renormalization group method with oblique projectors for an anisotropic tensor network, we confirm that the rescaled spectrum of transfer matrices at nonequilibrium…
Critical exponents in coupled phase-oscillator models on small-world networks
Ryosuke Yoneda, Kenji Harada, Yoshiyuki Y. Yamaguchi
A coupled phase-oscillator model consists of phase-oscillators, each of which has the natural frequency obeying a probability distribution and couples with other oscillators throug…
Finite- scaling analysis of Berezinskii-Kosterlitz-Thouless phase transitions and entanglement spectrum for the six-state clock model
Hiroshi Ueda, Kouichi Okunishi, Kenji Harada +4
We investigate the Berezinskii-Kosterlitz-Thouless transitions for the square-lattice six-state clock model with the corner-transfer matrix renormalization group (CTMRG). Scaling a…
