Loop-current order through the kagome looking glass
Rafael M. Fernandes, Turan Birol, Mengxing Ye +1
In loop-current states, interacting electronic degrees of freedom collectively establish interatomic currents, in a rare example of magnetism in which spin degrees of freedom do no…
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…

Xiao-Chuan Wu, Yichen Xu, Mengxing Ye +2
We discuss examples of two dimensional metallic states with charge fractionalization, and we will demonstrate that the mechanism of charge fractionalization leads to exotic metalli…
Ultrafast optical excitation of magnetic dynamics in van der Waals magnets: Coherent magnons and BKT dynamics in NiPS
Urban F. P. Seifert, Mengxing Ye, Leon Balents
Optical pump-probe experiments carried out in the time domain reveal both the intrinsic low energy dynamics and its connections to higher energy excitations in correlated electron…

Twisted bilayer graphene (TBG) aligned with hexagonal boron nitride (h-BN) substrate can exhibit an anomalous Hall effect at 3/4 filling due to the spontaneous valley polarization…

The search for fractionalization in quantum spin liquids largely relies on their decoupling with the environment. However, the spin-lattice interaction is inevitable in a real sett…
