Sound attenuation in the hyperhoneycomb Kitaev spin liquid

Kexin Feng, Aysel Shiralieva, Natalia B. Perkins

In recent years, it has been shown that the phonon dynamics may serve as an indirect probe of fractionalization of spin degrees of freedom. Here we propose that the sound attenuati…

Exploring amplitudes with violation by decomposition and on-shell scattering amplitude methods

Ke-Yao Feng, Xia Wan, You-Kai Wang +1

violation may play an important role in Baryogenesis in early universe, and should be examined at colliders comprehensively. We study properties of vertexes between…

Footprints of the Kitaev spin liquid in the Fano lineshapes of the Raman active optical phonons

Kexin Feng, Swetlana Swarup, Natalia B. Perkins

We develop a theoretical description of the Raman spectroscopy in the spin-phonon coupled Kitaev system and show that it can provide intriguing observable signatures of fractionali…

Temperature evolution of the phonon dynamics in the Kitaev spin liquid

Kexin Feng, Mengxing Ye, Natalia B. Perkins

Here we present a study of the phonon dynamics in the honeycomb Kitaev spin model at finite temperatures. We show that the fractionalized spin excitations of the Kitaev spin liquid…

Further insights into the thermodynamics of the Kitaev honeycomb model

Kexin Feng, Natalia B. Perkins, F. J. Burnell

Here we revisit the thermodynamics of the Kitaev quantum spin liquid realized on the honeycomb lattice. We address two main questions: First, we investigate whether there are obser…
