Chiral Weyl-Kondo semimetallic state through enhanced correlation in CeGaGe
Arushi, Kevin Allen, Yuan Fang +11
Strongly correlated chiral materials have been proposed to host a chiral Weyl-Kondo semimetal (cWKSM) state, in which Kondo hybridization pins chirality-induced Kramers-Weyl point…
Atomically-sharp magnetic soliton in the square-net lattice EuRhAlSi
Kevin Allen, Juba Bouaziz, Yichen Zhang +17
Topological spin textures are hallmark manifestations of competing interactions in magnetic matter. Their effective description by nonlinear field theories reflects an energetic fr…
Effect of Electron Correlation on the Integer Quantum Hall Effect
Daniel Staros, Christopher Lane, Roxanne Tutchton +1
We numerically investigate the effect of electron correlation on the integer quantum Hall effect in a square lattice. Increasing the correlation strength via the effective onsite r…
Magnetic order and physical properties of the Kagome metal UNbSn
Z. W. Riedel, W. Simeth, C. S. Kengle +8
The family of materials ( = rare-earth, = transition metal, = Ga, Si, Ge, Sn) produces an array of emergent phenomena, such as charge density waves, intrinsic…
UVSn: a new kagome material with unusual magnetism
S. M. Thomas, C. S. Kengle, W. Simeth +15
Materials in the family VSn ( rare earth) provide a unique platform to investigate the interplay between local moments from layers and nonmagnetic vanadium k…
Quantum Hall Effect in a Weyl-Hubbard Model: Interplay between Topology and Correlation
Snehasish Nandy, Christopher Lane, Jian-Xin Zhu
The interplay between topology and electronic correlation effects offers a rich avenue for discovering emergent quantum phenomena in condensed matter systems. In this work, startin…
Dark Matter Detection with Strongly Correlated Topological Materials: Flatband Effect
Zhao Huang, Christopher Lane, Sarah E. Grefe +5
Dirac materials have been proposed as a new class of electron-based detectors for light dark-matter (DM) scattering or absorption, with predicted sensitivities far exceeding superc…
Coexistence of Dirac Fermions and Magnons in a Layered Two-Dimensional Semiquinoid Metal-Organic Framework
Christopher Lane, Yixuan Huang, Lin Hou +1
We predict the magnetic and electronic properties of a novel metal-organic framework. By combining density functional theory and density matrix renormalization group approaches, we…
One-dimensionality signature in optical conductivity of heavy-fermion CeIrB
Bo Gyu Jang, Kenneth R. O'Neal, Christopher Lane +7
In low dimensions, the combined effects of interactions and quantum fluctuations can lead to dramatically new physics distinct from that existing in higher dimensions. Here, we inv…
An ab initio study of electron-hole pairs in a correlated van der Waals antiferromagnet: NiPS
Christopher Lane, Jian-Xin Zhu
The recently discovered two-dimensional (2D) van der Waals magnet NiPS provides a new route to examine many-body quasiparticles under 2D confinement. Excitons are of particular…
Colossal piezoresistance in narrow-gap Eu5In2Sb6
S. Ghosh, C. Lane, F. Ronning +5
Piezoresistance, the change of a material's electrical resistance () in response to an applied mechanical stress (), is the driving principle of electromechanical devices suc…
Electron correlations and charge density wave in the topological kagome metal FeGe
Chandan Setty, Christopher A. Lane, Lei Chen +3
Charge order in kagome metals is of extensive current interest. Recently, a charge density wave was discovered in the magnetic binary kagome metal FeGe. In analogy to its predecess…
Spin-polarized imaging of strongly interacting fermions in the ferrimagnetic state of Weyl candidate CeBi
Christian E. Matt, Yu Liu, Harris Pirie +8
CeBi has an intricate magnetic phase diagram whose fully-polarized state has recently been suggested as a Weyl semimetal, though the role of states in promoting strong interact…
