Cyclotron reonance in a kagome spin liquid candidate material
Byungmin Kang, Patrick A. Lee
We propose cyclotron resonance as an optical probe for emergent fractionalized excitations in quantum spin liquids, focusing on kagome antiferromagnets. In contrast…
Dirac node pinning from Dzyaloshinskii-Moriya interactions in a Kagome spin liquid
Ajesh Kumar, Byungmin Kang, Patrick A. Lee
Recent experiments on the Kagome spin liquid candidate YCOB suggest the presence of Dirac fermionic spinons near the magnetization plateau at 1/9. Theories suggest that the spinons…
Disorder-induced spin-cluster magnetism in a doped kagome spin liquid candidate
Arnab Seth, Joseph C. Prestigiacomo, Aini Xu +6
The search for new quantum spin liquid materials relies on systems with strong frustration such as spins on an ideal kagome lattice. However, lattice imperfections can have substan…
Thermodynamic evidence of fermionic behavior in the vicinity of one-ninth plateau in a kagome antiferromagnet
Guoxin Zheng, Dechen Zhang, Yuan Zhu +13
The spin-1/2 kagome Heisenberg antiferromagnets are believed to host exotic quantum entangled states. Recently, the report of 1/9 magnetization plateau and magnetic oscillations in…
Non-Analytic Magnetic Response and Intrinsic Ferromagnetic Clusters in a Dirac Spin Liquid Candidate
B. S. Shivaram, J. Prestigiacomo, Aini Xu +5
Finding distinct signatures of a quantum spin liquid (QSL) is an ongoing quest in condensed matter physics, invariably complicated by the presence of disorder in real materials. In…
Generation of gauge magnetic fields in a kagome spin liqud candidate using the Dzyaloshinskii-Moriya interaction
Byungmin Kang, Patrick A. Lee
The recent discovery of magnetization oscillations in a kagome spin liquid candidate motivates us to examine the origin of the gauge magnetic field term that can give rise to quant…
