Probing magnetic-field-induced multipolar ordering through field-angle-resolved magnetostriction and thermal expansion in PrIrZn
Naoki Okamoto, Yohei Kono, Takahiro Onimaru +3
We performed field-angle-resolved magnetostriction and thermal-expansion measurements on PrIrZn, a cubic non-Kramers compound exhibiting antiferroquadrupolar order below…
Anisotropy of the magnetic-field-induced phase pocket in the non-Kramers doublet system PrIrZn
Shunichiro Kittaka, Takahiro Onimaru, Keisuke T. Matsumoto +1
We provide thermodynamic evidence for the presence of a magnetic-field-induced small phase pocket near the antiferro-quadrupole (AFQ) phase boundary in the non-Kramers double…
Spectroscopic estimation of the photon number for superconducting Kerr parametric oscillators
Keisuke Matsumoto, Aiko Yamaguchi, Tsuyoshi Yamamoto +2
Quantum annealing (QA) is a way to solve combinational optimization problems. Kerr nonlinear parametric oscillators (KPOs) are promising devices for implementing QA. When we solve…
Calculation of Gibbs partition function with imaginary time evolution on near-term quantum computers
Keisuke Matsumoto, Yuta Shingu, Suguru Endo +5
The Gibbs partition function is an important quantity in describing statistical properties of a system in thermodynamic equilibrium. There are several proposals to calculate the pa…
Simultaneous collapse of antiferroquadrupolar order and superconductivity in PrIrZn by nonhydrostatic pressure
Kazunori Umeo, Riho Takikawa, Takahiro Onimaru +3
Superconductivity in PrIrZn appears at K in the presence of an antiferroquadrupolar order below K. We have studied pressure depen…
Single-Site Non-Fermi Liquid Behaviors in a Diluted 4 System YPrIrZn
Y. Yamane, T. Onimaru, K. Wakiya +3
Electrical resistivity and specific heat measurements have been made on the diluted 4 system Y(Pr)IrZn. Both data of and magnetic specific heat $C…
Highly anisotropic strain dependencies in PrIrZn
A. Wörl, T. Onimaru, Y. Tokiwa +4
We report thermal expansion and magnetostriction of the cubic non-Kramers system PrIrZn with a non-magnetic ground state doublet. In previous experiments…
Linear dichroism in angle-resolved core-level photoemission spectra reflecting 4f ground-state symmetry of strongly correlated cubic Pr compounds
Satoru Hamamoto, Shuhei Fujioka, Yuina Kanai +17
We report experimentally observed linear dichroism in angle-resolved core-level photoemission spectra of PrIr2Zn20 and PrB6 in cubic symmetry. The different anisotropic 4f charge d…
Quadrupole-Driven Non-Fermi Liquid and Magnetic-Field Induced Heavy Fermion States in a Non-Kramers Doublet System
T. Onimaru, K. Izawa, K. T. Matsumoto +9
Orbital degrees of freedom in condensed matters could play important roles in forming a variety of exotic electronic states by interacting with conduction electrons. In 4f electron…
Simultaneous Superconducting and Antiferroquadrupolar Transitions in PrRhZn
T. Onimaru, N. Nagasawa, K. T. Matsumoto +6
Superconducting and antiferroquadrupolar (AFQ) transitions in a Pr-based compound PrRh2Zn20 have been found to occur simultaneously at Tc=TQ=0.06 K. The superconducting transition…
