Chiral Valence-Bond Solid and Chiral Triplons
Shinnosuke Koyama, Kazumasa Hattori
We propose a chiral valence-bond solid (VBS) in which spin-singlet bond order itself spontaneously acquires handedness without magnetic order. Using a spin-lattice model on the dia…
Order parameter scaling of chirality in structural phase transitions
Keita Matsubara, Kazumasa Hattori
Chirality, defined by the absence of mirror and inversion symmetries, has attracted considerable attention owing to its unique physical phenomena, including cross-correlated respon…
Successive single- and double-q quadrupole orders on the diamond structure
Kaito Sasa, Kazumasa Hattori
We investigate field-dependent quadrupolar ordering at the L points of the diamond-structure Brillouin zone using classical Monte Carlo simulations of an effective quadrupole…
Collinear Magnetic Structure in the Diamond Network Magnet EuTiAl
Masahiro Kawamata, Ryuji Higashinaka, Takeshi Matsumura +5
The magnetic structure of EuTiAl, in which magnetic Eu ions form a diamond network, was investigated using neutron and resonant X-ray diffraction on powder and si…
Flexocurrent-induced magnetization: Strain gradient-induced magnetization in time-reversal symmetric systems
Shinnosuke Koyama, Takashi Koretsune, Kazumasa Hattori
Symmetry constraints determine which physical responses are allowed in a given system. Magnetization induced by strain fields, such as in piezomagnetic and flexomagnetic effects, h…
Kondo-Peierls transition with nonsymmorphic zone boundary gap formation
Kazumasa Hattori, Hiroaki Kusunose
We study nonsymmorphic space group symmetry breakings in correlated electron systems. Under nonsymmorphic symmetry, it is well known that there are degeneracies in the electronic B…
Spin-flip Scattering at a Chiral Interface of Helical Chains
Keita Matsubara, Kazumasa Hattori
We investigate spin-flip scattering processes of electrons when they pass a chiral interface, which is the boundary between right- and left-handed one-dimensional chain. We constru…
