High-Precision Variational Quantum SVD via Classical Orthogonality Correction
Shohei Miyakoshi, Takanori Sugimoto, Tomonori Shirakawa +2
Evaluating the entanglement spectrum is essential for characterizing exotic quantum phases such as quantum criticality and topological order. However, for large quantum many-body s…
Quantum-Inspired Algorithm for Classical Spin Hamiltonians Based on Matrix Product Operators
Ryo Watanabe, Joseph Tindall, Shohei Miyakoshi +1
We propose a tensor-network (TN) approach for solving classical optimization problems that is inspired by spectral filtering and sampling on quantum states. We first shift and scal…
Diamond-shaped quantum circuit for real-time quantum dynamics in one dimension
S. Miyakoshi, T. Sugimoto, T. Shirakawa +2
In recent years, quantum computing has evolved as an exciting frontier, with the development of numerous algorithms dedicated to constructing quantum circuits that adeptly represen…
Photoinduced pairing in the Kondo lattice model
Tomonori Shirakawa, Shohei Miyakoshi, Seiji Yunoki
The previous theoretical study has shown that pulse irradiation to the Mott insulating state in the Hubbard model can induce the enhancement of superconducting correlation due to t…
Spin texture and spin current in excitonic phases of the two-band Hubbard model
Hisao Nishida, Shohei Miyakoshi, Tatsuya Kaneko +2
Using the mean-field approximation, we study the -space spin textures and local spin currents emerged in the spin-triplet excitonic insulator states of the two-band Hubbard mode…
Correlation-Driven Dimerization and Topological Gap Opening in Isotropically Strained Graphene
Sandro Sorella, Kazuhiro Seki, Oleg O. Brovko +4
The phase diagram of isotropically expanded graphene cannot be correctly predicted by ignoring either electron correlations, or mobile carbons, or the effect of applied stress, as…
