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…
Thermal effects versus spin nematicity in a frustrated spin-1/2 chain
M. Pregelj, A. Zorko, D. Arčon +5
The spin-nematic phase is an intriguing state of matter that lacks usual long-range dipolar order, yet it exhibits higher multipolar order. This makes its detection extremely diffi…
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,…
Chirality-driven ferroelectricity in LiCuVO
Alexander Ruff, Peter Lunkenheimer, Hans-Albrecht Krug von Nidda +5
Chirality or the handedness of objects is of prime importance in life science, biology, chemistry and physics. It is also a major symmetry ingredient in frustrated magnets revealin…
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…
