One-dimensional conduction channels in the correlated Mott NiS2 arising from obstructed Wannier charges
Mikel Iraola, Haojie Guo, Fabio Orlandi +9
NiS2, a compound characterized by its pyrite structure, uniquely bridges the realms of strong correlation physics and topology. While bulk NiS2 is known to be a Mott or charge-tran…
Materials Expert-Artificial Intelligence for Materials Discovery
Yanjun Liu, Milena Jovanovic, Krishnanand Mallayya +5
The advent of material databases provides an unprecedented opportunity to uncover predictive descriptors for emergent material properties from vast data space. However, common reli…
Chemical tuning of a honeycomb magnet through a critical point
Austin M. Ferrenti, Maxime A. Siegler, Shreenanda Ghosh +9
BaCo2(AsO4)2 (BCAO) has seen extensive study since its initial identification as a proximate Kitaev quantum spin liquid candidate. Thought to be described by the highly anisotropic…
Photoinduced Band Renormalization Effects in ZrSiS Topological Nodal-line Semimetal
Somnath Biswas, Ioannis Petrides, Robert J. Kirby +7
Out-of-equilibrium effects provide an elegant pathway to probing and understanding the underlying physics of topological materials. Creating exotic states of matter using ultrafast…
One-Dimensional Luttinger Liquids in a Two-Dimensional Moiré Lattice
Pengjie Wang, Guo Yu, Yves H. Kwan +13
The Luttinger liquid (LL) model of one-dimensional (1D) electronic systems provides a powerful tool for understanding strongly correlated physics including phenomena such as spin-c…
Signature of an Ultrafast Photo-Induced Lifshitz Transition in the Nodal-Line Semimetal ZrSiTe
Robert J. Kirby, Lukas Muechler, Sebastian Klemenz +6
Here we report an ultrafast optical spectroscopic study of the nodal-line semimetal ZrSiTe. Our measurements reveal that, converse to other compounds of the family, the sudden inje…
Evidence for a Monolayer Excitonic Insulator
Yanyu Jia, Pengjie Wang, Cheng-Li Chiu +19
The interplay between topology and correlations can generate a variety of quantum phases, many of which remain to be explored. Recent advances have identified monolayer WTe2 as a p…
Landau Quantization and Highly Mobile Fermions in an Insulator
Pengjie Wang, Guo Yu, Yanyu Jia +9
In strongly correlated materials, quasiparticle excitations can carry fractional quantum numbers. An intriguing possibility is the formation of fractionalized, charge-neutral fermi…
Weyl-fermions, Fermi-arcs, and minority-spin carriers in ferromagnetic CoS2
Niels B. M. Schröter, Iñigo Robredo, Sebastian Klemenz +15
The pyrite compound CoS2 has been intensively studied in the past due to its itinerant ferromagnetism and potential for half-metallicity, which make it a promising material for spi…
Transient Drude Response Dominates Near-Infrared Pump-Probe Reflectivity in Nodal-Line Semimetals ZrSiS and ZrSiSe
Robert J. Kirby, Austin Ferrenti, Caroline Weinberg +6
The ultrafast optical response of two nodal-line semimetals, ZrSiS and ZrSiSe, was studied in the near-infrared using transient reflectivity. The two materials exhibit similar resp…
The role of delocalized chemical bonding in square-net-based topological semimetals
Sebastian Klemenz, Aurland K. Hay, Samuel M. L. Teicher +3
Principles that predict reactions or properties of materials define the discipline of chemistry. In this work we derive chemical rules, based on atomic distances and chemical bond…
A systematic study of stacked square nets: from Dirac fermions to material realizations
Sebastian Klemenz, Leslie Schoop, Jennifer Cano
Non-symmorphic symmetries protect Dirac line nodes in square net materials. This phenomenon has been most prominently observed in ZrSiS. Here, we systematically study the symmetry-…
High mobility in a van der Waals layered antiferromagnetic metal
Shiming Lei, Jingjing Lin, Yanyu Jia +13
Magnetic van der Waals (vdW) materials have been heavily pursued for fundamental physics as well as for device design. Despite the rapid advances, so far magnetic vdW materials are…
Topological Semimetals in Square-Net Materials
Sebastian Klemenz, Shiming Lei, Leslie M. Schoop
Many materials crystallize in structure types that feature a square-net of atoms. While these compounds can exhibit many different properties, some members of this family are topol…
