Quantum Scalar Spin Chirality in Coplanar Kagome Antiferromagnets
Nanse Esaki, Gyungchoon Go, Se Kwon Kim
We theoretically demonstrate that quantum fluctuations inherent to antiferromagnets can generate scalar spin chirality at zero temperature even in coplanar ordered magnets. In a ka…
Spin Nernst and thermal Hall effects of topological triplons in quantum dimer magnets on the maple-leaf and star lattices
Nanse Esaki, Yutaka Akagi, Karlo Penc +1
We present a comprehensive theoretical study of the topological properties of triplon excitations in spin-1/2 dimer-singlet ground states defined on the maple leaf and star lattice…
Magnon-induced scalar spin chirality in Kagome and honeycomb ferromagnets
Nanse Esaki, Gyungchoon Go, Se Kwon Kim
The scalar spin chirality (SSC), defined as a triple product of spins, is essential for describing noncoplanar spin structures and understanding chiral physics in magnetic systems.…
Scalar Spin Chirality Hall Effect
Gyungchoon Go, Durga Prasad Goli, Nanse Esaki +2
The scalar spin chirality, which characterizes the fundamental unit of noncoplanar spin structures, plays an important role in rich chiral physics of magnetic materials. In particu…
Electric field induced thermal Hall effect of triplons in the quantum dimer magnets CuCl ( Tl, K)
Nanse Esaki, Yutaka Akagi, Hosho Katsura
We theoretically propose the electric field induced thermal Hall effect of triplons in the quantum dimer magnets CuCl ( Tl, K), which exhibit ferroelectricity in the…
