“…Temperature-induced Lifshitz transitions are also observed in other TSMs, for example, MTe 5 (M = Zr, Hf) 26 , 27 , InTe 1-δ 28 , ZrSiSe 29 , WTe 2 30 , and TaIrTe 4 31 . Anomalies in both longitudinal resistivity and Hall resistivity/coefficient can be found in MTe 5 (M = Zr, Hf) 26 , 27 , InTe 1-δ 28 , and ZrSiSe 29 , but not in WTe 2 30 and TaIrTe 4 31 . Since we have observed the change of Hall resistivity in EuAs 3 (Fig.…”

Magnetism-induced topological transition in EuAs3

The nature of the interaction between magnetism and topology in magnetic topological semimetals remains mysterious, but may be expected to lead to a variety of novel physics. We systematically studied the magnetic semimetal EuAs3, demonstrating a magnetism-induced topological transition from a topological nodal-line semimetal in the paramagnetic or the spin-polarized state to a topological massive Dirac metal in the antiferromagnetic ground state at low temperature. The topological nature in the antiferromagnetic state and the spin-polarized state has been verified by electrical transport measurements. An unsaturated and extremely large magnetoresistance of ~2 × 105% at 1.8 K and 28.3 T is observed. In the paramagnetic states, the topological nodal-line structure at the Y point is proven by angle-resolved photoemission spectroscopy. Moreover, a temperature-induced Lifshitz transition accompanied by the emergence of a new band below 3 K is revealed. These results indicate that magnetic EuAs3 provides a rich platform to explore exotic physics arising from the interaction of magnetism with topology.

“…On the other hand, based on the consistent picture provided by the shifts, the (T 1 T ) −1 , and linewidth it is clear that μ(T ) has a large T -dependence and crosses the protected node at low T . In Zr-SiSe, transport results were recently proposed to give evidence for even larger T -induced changes of μ [15]. For the present case, we assume relative shifts of band energies contribute to this process causing the node to shift relative to μ, perhaps induced by the promotion of carriers from donor states, in a manner akin to the changes that have been proposed [17] to accompany the optical promotion of carriers in ZrSiTe.…”

“…Its large region of topologically protected drumhead surface states [13] as well as very large spin Berry curvature and associated spin Hall and Nernst response [14] suggest spintronic and related applications. Suggested changes of Fermi surface topology in this family include a temperature-induced Lifshitz transition in ZrSiSe [15], and a pressure-induced Lifshitz transition in ZrSiTe [16] as well as indications of a photoinduced phonon driven transformation [17].…”

We have applied nuclear magnetic resonance spectroscopy to study the distinctive network of nodal lines in the Dirac semimetal ZrSiTe. The low-T behavior is dominated by a symmetry-protected nodal line, with NMR providing a sensitive probe of the diamagnetic response of the associated carriers. A sharp low-T minimum in the NMR shift and (T 1 T ) −1 provides a quantitative measure of the dispersionless, quasi-two-dimensional behavior of this nodal line. We also identify a Van Hove singularity closely connected to this nodal line, and an associated T -induced Lifshitz transition. A disconnect in the NMR shift and linewidth at this temperature indicates the change in electronic behavior associated with this topological change. These features have an orientation-dependent behavior indicating a field-dependent scaling of the associated band energies.

“…Topologically protected surface states were observed in ZrSiSe, linking with bulk bands together . These features are close to achieving a Lifshitz transition via adjusting some external parameters, such as temperature . In addition, a spin–orbit coupling (SOC) gap (20–60 meV) was predicted, which can destroy the nodal-line structure. , These fascinating properties motivate us to further investigate the isostructural ZrSiX compounds.…”

Pressure-Induced Electronic and Structural Transition in Nodal-Line Semimetal ZrSiSe

The nodal-line semimetals have recently gained attention as a promising material due to their exotic electronic structure and properties. Here, we investigated the structural evolution and physical properties of nodal-line semimetal ZrSiSe under pressure via experiments and theoretical calculations. An isostructural electronic transition is observed at ∼6 GPa. Upon further compression, the original tetragonal phase starts to transform into an orthorhombic phase at ∼13 GPa and the two phases coexist until the maximal experimental pressure. By analysis of the electronic band structure, we suggest that the significant changes in the Fermi surface contribute to the occurrence of the isostructural electronic transition. The results provide a new insight into the structure and properties of ZrSiSe.
