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…
Quantum phases driven by strong correlations
Silke Paschen, Qimiao Si
It has long been thought that strongly correlated systems are adiabatically connected to their noninteracting counterpart. Recent developments have highlighted the fallacy of this…
Incommensurate Spin Fluctuations in the Spin-triplet Superconductor Candidate UTe
Chunruo Duan, Kalyan Sasmal, M. Brian Maple +4
Spin-triplet superconductors are of extensive current interest because they can host topological state and Majorana ferimons important for quantum computation. The uranium based he…
Pristine quantum criticality in a Kondo semimetal
W. T. Fuhrman, A. Sidorenko, J. Hänel +8
The observation of quantum criticality in diverse classes of strongly correlated electron systems has been instrumental in establishing ordering principles, discovering new phases,…
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…
