Tunable spin-phonon polarons in a chiral molecular qubit framework
Aimei Zhou, Ruihao Bi, Zhenghan Zhang +22
Chiral structures that produce asymmetric spin-phonon coupling can theoretically generate spin-phonon polarons -- quasiparticles exhibiting non-degenerate spin states with phonon d…

Lattice dynamics and spin-phonon coupling in the kagome spin ice HoAgGe
Shangfei Wu, Lingxiao Zhao, Wei Song +5
We employ polarization-resolved Raman spectroscopy and first-principles phonon calculations to study the lattice dynamics and spin-phonon coupling in the kagome spin ice compound H…
