Reversible Non-Volatile Electronic Switching in a Near Room Temperature van der Waals Ferromagnet
Han Wu, Lei Chen, Paul Malinowski +37
The ability to reversibly toggle between two distinct states in a non-volatile method is important for information storage applications. Such devices have been realized for phase-c…
Metallic quantum criticality enabled by flat bands in a kagome lattice
Lei Chen, Fang Xie, Shouvik Sur +4
Strange metals arise in a variety of platforms for strongly correlated electrons, ranging from the cuprates, heavy fermions to flat band systems. Motivated by recent experiments in…
Symmetry constraints and spectral crossing in a Mott insulator with Green's function zeros
Chandan Setty, Shouvik Sur, Lei Chen +5
Lattice symmetries are central to the characterization of electronic topology. Recently, it was shown that Green's function eigenvectors form a representation of the space group. T…
Extended Dynamical Mean Field Theory for Correlated Electron Models
Haoyu Hu, Lei Chen, Qimiao Si
An overarching question in strongly correlated electron systems is how the landscape of quantum phases emerges from electron correlations. The method of extended dynamical mean fie…
Quantum critical metals and loss of quasiparticles
Haoyu Hu, Lei Chen, Qimiao Si
Strange metals develop near quantum critical points in a variety of strongly correlated systems. Some of the issues that are central to the field include how the quantum-critical s…
Topological semimetals without quasiparticles
Haoyu Hu, Lei Chen, Chandan Setty +8
The interplay between interactions and topology in quantum materials is of extensive current interest. Strong correlations are known to be important for insulating topological stat…
Unconventional Superconductivity from Fermi Surface Fluctuations in Strongly Correlated Metals
Haoyu Hu, Ang Cai, Lei Chen +4
In quantum materials, electrons that have strong correlations tend to localize, leading to quantum spins as the building blocks for low-energy physics. When strongly correlated ele…
Spin-singlet and spin-triplet pairing correlations in antiferromagnetically coupled Kondo systems
Haoyu Hu, Ang Cai, Lei Chen +1
Recent experiments in quantum critical heavy fermion metals have pushed to the fore the question about whether antiferromagnetic fluctuations can promote both spin-singlet and spin…
Topological Semimetal driven by Strong Correlations and Crystalline Symmetry
Lei Chen, Chandan Setty, Haoyu Hu +9
Electron correlations amplify quantum fluctuations and, as such, they have been recognized as the origin of a rich landscape of quantum phases. Whether and how they lead to gapless…
Electron correlations and -breaking density wave order in a kagome metal
Chandan Setty, Haoyu Hu, Lei Chen +1
There have been extensive recent developments on kagome metals, such as TX (T= Fe, Co and X= Sn, Ge) and VSb ( Cs, K, Rb). An emerging issue is the nature of…
Fragile Insulator and Electronic Nematicity in a Graphene Moire System
Lei Chen, Haoyu Hu, Qimiao Si
Strongly correlated quantum matter exhibits a rich variety of remarkable properties, but the organizing principles that underlie the behavior remain to be established. Graphene het…
