Deep variational quantum eigensolver for excited states and its application to quantum chemistry calculation of periodic materials
Kaoru Mizuta, Mikiya Fujii, Shigeki Fujii +4
A programmable quantum device that has a large number of qubits without fault-tolerance has emerged recently. Variational Quantum Eigensolver (VQE) is one of the most promising way…
Current patterns and magnetic impurities in time-reversal breaking superconductor
Yikihiro Okuno
We study the impurity effect in the time reversal symmetry () breaking superconductor based on the Bogoliubov-de Gennes (BdG) equations. In -violating supercond…
Analysis of impurity-induced circular currents for the chiral superconductor Sr_{2}RuO_{4}
Yukihiro Okuno, Masashige Matsumoto, Mangred Sigrist
The microscopic mechanism of circular currents induced in the vicinity of a non-magnetic impurity is analyzed for the (time-reversal symmetry breaking) chiral superconducting state…
Anomalous Magnetism of UPT_{3}:
Yukihiro Okuno, Kazumasa Miyake
UPt exhibits a paradoxical behavior in its antiferromagnetism. Namely, the neutron scattering experiments surely detect the antifferomagnetic ordering below the transition…
Induced-Moment Weak Antiferromagnetism and Orbital Order on the Itinerant-Localized Duality Model with Nested Fermi Surface: A Possible Origin of Exotic Magnetism in URuSi
Yukihiro Okuno, Kazumasa Miyake
The weak antiferromagnetism of URuSi is discussed on the basis of a duality model which takes into account salient features of both itinerant fermions and "localize…
Renormalized Perturbation Approach for Examination of Itinerant-Localized Duality Model for Strongly Correlated Electron Systems
Yukihiro Okuno, Osamu Narikiyo, Kazumasa Miyake
We present a microscopic examination for the itinerant-localized duality model which has been proposed to understand anomalous properties of strongly correlated systems like the he…
