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…
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…
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…
Extreme topological tunability of Weyl-Kondo semimetal to Zeeman coupling
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
There is considerable interest in the intersection of correlations and topology, especially in metallic systems. Among the outstanding questions are how strong correlations drive n…
Inhomogeneous Kondo-lattice in geometrically frustrated PrIrO
Mariam Kavai, Joel Friedman, Kyle Sherman +12
Magnetic fluctuations induced by geometric frustration of local Ir-spins disturb the formation of long range magnetic order in the family of pyrochlore iridates, RIrO$_…
Weyl-Kondo Semimetal: Towards Control of Weyl Nodes
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
Heavy fermion semimetals represent a promising setting to explore topological metals driven by strong correlations. In this paper, we i) summarize the theoretical results in a Weyl…
Weyl-Kondo semimetals in nonsymmorphic systems
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
There is considerable current interest to explore electronic topology in strongly correlated metals, with heavy fermion systems providing a promising setting. Recently, a Weyl-Kond…
Giant spontaneous Hall effect in a nonmagnetic Weyl-Kondo semimetal
Sami Dzsaber, Xinlin Yan, Mathieu Taupin +9
Nontrivial topology in condensed matter systems enriches quantum states of matter, to go beyond either the classification into metals and insulators in terms of conventional band t…
Weyl-Kondo Semimetal in Heavy Fermion Systems
Hsin-Hua Lai, Sarah E. Grefe, Silke Paschen +1
Insulating states can be topologically nontrivial, a well-established notion that is exemplified by the quantum Hall effect and topological insulators. By contrast, topological met…
Anomalous Hall effect and quantum criticality in geometrically frustrated heavy fermion metals
Wenxin Ding, Sarah Grefe, Silke Paschen +1
Studies on the heavy-fermion pyrochlore iridate (PrIrO) point to the role of time-reversal-symmetry breaking in geometrically frustrated Kondo lattices. With this motiv…
Approximations of potentials through the truncation of their inverses
N. C. Brown, S. E. Grefe, Z. Papp
The inverse of an symmetric band matrix can be constructed in terms of a matrix continued fraction. For Hamiltonians with Coulomb plus polynomial potentials,…
