Emergence of Kondo-assisted Néel order in a Kondo necklace model
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +3
The interplay between Kondo screening and magnetic order has long been a central issue in the physics of strongly correlated systems. While the Kondo effect has traditionally been…
Realization of a Spin-1/2 Hexagonal-Plaquette Chain with Ising-Like Anisotropy
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +2
We present the realization of a spin-1/2 hexagonal-plaquette chain with Ising anisotropy, an unexplored quantum spin model that serves as a platform for investigating anisotropic q…
Quantum phase with spontaneous translational symmetry breaking in an extended diamond chain
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +2
We report the experimental realization of a spin-1/2 extended diamond chain in a verdazyl-Cu complex, where competing interactions and lattice distortions give rise to exotic quant…
Half Landau-Zener ramp to a quantum phase transition in a dissipative single spin sodel
Sei Suzuki
We study the dynamics of a single spin coupled to a bosonic bath at zero temperature driven by a ramp of the bias field. A single spin coupled to a bosonic sub-Ohmic bath exhibits…
Spin pumping into quantum spin chains
Shunsuke C. Furuya, Mamoru Matsuo, Takeo Kato
We theoretically investigate spin pumping into a quantum easy-plane ferromagnetic spin chain system. This quantum spin chain is effectively described by the Tomonaga-Luttinger (TL)…
Griffiths-type theorems for short-range spin glass models
Chigak Itoi, Hisamitsu Mukaida, Hal Tasaki
We establish relations between different characterizations of order in spin glass models. We first prove that the broadening of the replica overlap distribution indicated by a nonz…
