Quantum Fisher information of magnetic quantum phase transition on Kondo lattice
Yuan Fang, Lei Chen, Mounica Mahankali +4
Strange metals exemplify highly collective quantum many-body systems that call for new means of characterization, and there is considerable potential for quantum information approa…
Magnetic Order in bilayer Ruddlesden-Popper Nickelates
Yiming Wang, Guijing Duan, Zhiguang Liao +3
The paper models the magnetic order in the bilayer nickelate La₃Ni₂O₇ as arising from local moments interacting via combined RKKY and superexchange couplings, predicting a wavevect…
Amplified response of cavity-coupled quantum-critical systems
Shouvik Sur, Yiming Wang, Mounica Mahankali +2
A quantum critical point develops when matter undergoes a continuous transformation between distinct ground states at absolute zero. It hosts pronounced quantum fluctuations, which…
Perturbative Kondo destruction and global phase diagram of heavy fermion metals
Yiming Wang, Shouvik Sur, Chia-Chuan Liu +1
Strange metals represent a foundational problem in quantum condensed matter physics, and heavy fermion systems provide a canonical setting to advance a general understanding. The c…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Kondo destruction quantum critical point: fixed point annihilation and thermodynamic stability
Yiming Wang, Lei Chen, Haoyu Hu +4
A wide range of strongly correlated electron systems exhibit strange metallicity, and they are increasingly recognized as in proximity to correlation-driven localization-delocaliza…
