Direct Raman observation of the quantum metric in a quantum magnet
Chao-Fan Wang, Han Ge, Jun-Yang Chen +4
The quantum geometric tensor (QGT) unifies the Berry curvature (its imaginary part) and the quantum metric (its real part), yet Raman studies of chiral phonons have so far accessed…
Possible Observation of Quadrupole Waves in Spin Nematics
Jieming Sheng, Jiahang Hu, Lei Xu +15
Discovery of new states of matter is a key objective in modern condensed matter physics, which often leads to revolutionary technological advancements such as superconductivity. Qu…
Simulating Bulk Gap in Chiral Projected Entangled-Pair States
Ji-Yao Chen, Yi Tan, Sylvain Capponi +3
Projected entangled-pair states (PEPS) have proven effective in capturing chiral spin liquid ground states, yet the presence of long-range ``gossamer'' correlation tails raises con…
Berezinskii-Kosterlitz-Thouless region and magnetization plateaus in easy-axis triangular weak-dimer antiferromagnet KCo(SeO)
Ying Fu, Han Ge, Jian Chen +11
We investigate the magnetic phase diagram of the bilayer triangular antiferromagnet KCo(SeO), revealing a rich interplay among geometric frustration, bilayer coupli…
