Volatile resistive-switched state in a bulk organic conductor with a sharp metal-insulator transition

Riku Ishii, Ryo Motohashi, Keitaro Tada +6

Volatile resistive switching in correlated-electron systems, characterized by an abrupt resistance decrease under applied current, is crucial for developing next-generation electro…

Incommensurate Magnetic Ordered Phase with Enhanced Low-Temperature Magnetic Specific Heat in SmAu $_{3}$ Al $_{7}$

Ryuji Higashinaka, Takuma Iwami, Kohsuke Saitou +12

Neutron scattering and muon spin rotation ( $μ$ SR) measurements on single-crystal SmAu $_{3}$ Al $_{7}$ reveal magnetically ordered states associated with successive transitions at $T_{\rm…

Generalized Nagaoka ferromagnetism accompanied by flavor-selective Mott states in an SU( $N$ ) Fermi-Hubbard model

Juntaro Fujii, Kazuki Yamamoto, Akihisa Koga

We study the ferromagnetic instability in an SU( $N$ ) Fermi-Hubbard model on the hypercubic lattice. Combining dynamical mean-field theory with continuous-time quantum Monte Carlo s…

Critical Berezinskii-Kosterlitz-Thouless dynamics in the archetypal two-dimensional spin system Ba $_{2}$ CuSi $_{2}$ O $_{6}$ Cl $_{2}$

K. M. Ranjith, Maxime Dupont, Steffen Krämer +6

We study the spin dynamics in the quasi-2D spin- $1/2$ dimer compound Ba $_{2}$ CuSi $_{2}$ O $_{6}$ Cl $_{2}$ , which exhibits a magnetic field-induced Bose-Einstein condensate (BEC) of triplons.…

Kondo breakdown induced by non-Hermitian complex hybridization

Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami

Recently, a non-Hermitian Anderson impurity model with one-body loss has been studied in [Phys. Rev. B 111, 125157 (2025)}], and it has been demonstrated that the renormalization e…

Holographic Aspects of Dynamical Mean-Field Theory

Kouichi Okunishi, Akihisa Koga

Dynamical mean-field theory (DMFT) is one of the most standard theoretical frameworks for addressing strongly correlated electron systems. In this study, we explore a holographic r…

Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet

Ayano Nakamura, Shinichi Nishihaya, Mitsuru Akaki +9

The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal…

Reexamination of the charge-ordered dimer pattern in the spinel compound CuIr2S4 using single-crystal synchrotron x-ray diffraction

T. Ohashi, N. Katayama, K. Kojima +11

We have re-investigated the crystal structure of a spinel type CuIr2S4 at low temperatures using a single-crystal in a synchrotron radiation x-ray diffraction experiment. The cryst…

Dirac Magnon in Honeycomb Lattice Magnet NiTiO3

Hodaka Kikuchi, Makoto Ozeki, Nobuyuki Kurita +4

We performed inelastic neutron scattering experiments on single-crystal samples of the honeycomb lattice magnet, ilmenite NiTiO3. Below the Neel temperature of 22 K, spin wave exci…

On the cuprates' universal waterfall feature: evidence of a momentum-driven crossover

Benjamin Bacq-Labreuil, Chafic Fawaz, Yuichi Okazaki +13

We study two related universal anomalies of the spectral function of cuprates, so called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory…
