Crucial role of thermal fluctuations and vertex corrections for the magnetic pseudogap
Mengxing Ye, Andrey V. Chubukov
It is generally believed that in a 2D metal, whose ground state is antiferromagnetically ordered with , thermal (static) magnetic fluctuations give rise to precurs…

Location and thermal evolution of the pseudogap due to spin fluctuations
Mengxing Ye, Zhentao Wang, Rafael M Fernandes +1
We study pseudogap behavior in a metal near a spin density wave (SDW) instability due to thermal magnetic fluctuations. We consider the Hubbard model on a square lattice at…

Fractionalized Excitations Probed by Ultrasound
A. Hauspurg, S. Zherlitsyn, T. Helm +8
In this work, we study magnetoelastic interactions by means of ultrasound experiments in -RuCl -- a prototypical material for the Kitaev spin model on the honeycomb lattice,…
