Elastoresistivity Signatures of Nematic Fluctuations in Layered Antiferromagnet CoTa3S6
Tao Lu, Zili Feng, Mengxing Ye +2
Nematic phases that break rotational symmetry are widely observed in quantum materials, and clarifying their origin and relationship with other symmetry-breaking phases remains an…
A Quantum Many-Body Approach for Orbital Magnetism in Correlated Multiband Electron Systems
Mengxing Ye
Orbital magnetism is a purely quantum phenomenon that reflects intrinsic electronic properties of solids, yet its microscopic description in interacting multiband systems remains i…
Nonvolatile Nematic Order Manipulated by Strain and Magnetic Field in a Layered Antiferromagnet
Zili Feng, Weihang Lu, Tao Lu +6
The operation mechanism of nematic liquid crystals lies in the control of their optical properties by the orientation of underlying nematic directors. In analogy, electronic nemati…
Coadjoint-orbit bosonization of a Fermi surface in a weak magnetic field
Mengxing Ye, Yuxuan Wang
We present a bosonized effective field theory for a 2d Fermi surface in a weak magnetic field using the coadjoint orbit approach, which was recently developed as a nonlinear bosoni…
Distinct Optical Excitation Mechanisms of a Coherent Magnon in a van der Waals Antiferromagnet
Clifford J. Allington, Carina A. Belvin, Urban F. P. Seifert +9
The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz f…
Berry Phase and Quantum Oscillation from Multi-orbital Coadjoint-orbit Bosonization
Mengxing Ye, Yuxuan Wang
We develop an effective field theory for a multi-orbital fermionic system using the method of coadjoint orbits for higher-dimensional bosonization. The dynamical bosonic fields are…
