Arbitrary Chern number generation in the three-band model from momentum space

Soo-Yong Lee, Jin-Hong Park, Gyungchoon Go +1

A simple, general rule for generating a three-band model with arbitrary Chern numbers is given. The rule is based on the idea of monopole charge-changing unitary operations and can…

Magnon condensation with finite degeneracy on the triangular lattice

Giacomo Marmorini, Tsutomu Momoi

We study the spin 1/2 triangular-lattice $J_{1}$ - $J_{2}$ - $J_{3}$ antiferromagnet close to the saturation field using the dilute Bose gas theory, where the magnetic structure is determine…

Static magnetic moments revealed by muon spin relaxation and thermodynamic measurements in quantum spin ice Yb $_{2}$ Ti $_{2}$ O $_{7}$

Lieh-Jeng Chang, Martin R. Lees, Isao Watanabe +3

We present muon spin relaxation ( $μ$ SR) and specific-heat versus temperature $C (T)$ measurements on polycrystalline and single-crystal samples of the pyrochlore magnet Yb $_{2}$ Ti $_{2}$ …

Bulk Nature of Layered Perovskite Iridates beyond the Mott Scenario : An Approach from Bulk Sensitive Photoemission Study

A. Yamasaki, S. Tachibana, H. Fujiwara +24

We present genuine bulk Ir 5d jeff states of layered perovskite iridates obtained by hard-x-ray photoemission spectroscopy (HAXPES) with s- and p-polarized lights. HAXPES spectra o…

Stiffness from Disorder in Triangular-Lattice Ising Thin Films

Shi-Zeng Lin, Yoshitomo Kamiya, Gia-Wei Chern +1

We study the triangular lattice Ising model with a finite number of vertically stacked layers and demonstrate a low temperature reentrance of two Berezinskii-Kosterlitz-Thouless tr…

Ferromagnetic cluster-glass state in itinerant electron system Sr1-xLaxRuO3

Ikuto Kawasaki, Makoto Yokoyama, Suguru Nakano +4

The magnetic and electronic properties of Sr1-xLaxRuO3 were studied by means of dc-magnetization, ac-susceptibility, specific heat, and electrical resistivity measurements. The dc-…
