Phonon dynamics in the chiral Kitaev spin liquid

S Singh, PP Stavropoulos, NB Perkins - Physical Review B, 2024 - APS
We investigate the effect of a magnetic field on the extended Kitaev spin-liquid state through
phonon dynamics. Using a constrained fermionic self-consistent mean field method, we …

Phonon dynamics in the site-disordered Kitaev spin liquid

V Dantas, WH Kao, NB Perkins - Physical Review B, 2024 - APS
The Kitaev honeycomb model provides a paradigmatic example of an exactly solvable
quantum spin liquid (QSL), where spins fractionalize into itinerant Majorana fermions …

Kitaev Quantum Spin Liquids

Y Matsuda, T Shibauchi, HY Kee - arxiv preprint arxiv:2501.05608, 2025 - arxiv.org
Quantum spin liquids (QSLs) represent exotic states of matter where quantum spins interact
strongly yet evade long-range magnetic order down to absolute zero. Characterized by non …

Magnetization process of a quasi-two-dimensional quantum magnet: Two-step symmetry restoration and dimensional reduction

We report on a comprehensive thermodynamic study of a quasi-two-dimensional (quasi-2D)
quantum magnet Cu $ _2 $(OH) $ _3 $ Br which in the 2D layer can be viewed as strongly …

Signatures of fractionalization in the optical phonons of the hyperhoneycomb Kitaev magnet

S Swarup, S Singh, NB Perkins - Physical Review B, 2024 - APS
In this study, we propose that the signatures of spin fractionalization in quantum magnets
can be identified through a detailed analysis of the temperature dependence of the …

[HTML][HTML] Spin-dependent electron–phonon interaction on quantum transport through an Aharonov-Bohm interferometer with a quantum dot connected to Majorana …

FB Yang, H Liu - Results in Physics, 2024 - Elsevier
We theoretically investigate the spin-dependent transport through an Aharonov-Bohm
interferometer in the presence of electron phonon interaction. We calculate the spectral …
