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…
Stealthy hyperuniform disorder: A new route to controlling electric states and magnetic phase transition in correlated systems
Akihisa Koga, Takanori Sugimoto
We investigate the effects of stealthy hyperuniform bond distributions on the electronic and magnetic properties of the Hubbard model on the honeycomb lattice. Hyperuniform structu…
Identification of Two Distinct Antiferromagnetic Phases in the Au-Al-Gd Quasicrystal Approximant
Farid Labib, Takanori Sugimoto, Hiroyuki Takakura +2
The structural and physical properties of two single-grain Au-Al-Gd 1/1 approximant crystals (ACs) with analyzed compositions Au73.67Al12.24Gd14.09 and Au74.67Al11.35Gd13.98 were t…
Anomalous magnetic transition in a disordered quasicrystal approximant with heavy-fermion nature
Takayuki Shiino, Farid Labib, Yuma Hirano +7
Quasicrystal approximant (CexY1-x)Cd6 (0 < x < 1) forms a network of corner-sharing octahedra. We report that (Ce0.8Y0.2)Cd6 exhibits an anomalous magnetic transition which can be…
