CHARGE ORDER AND STRUCTURAL TRANSITION IN TOPOLOGICAL SEMIMETAL FAMILY AAL4
… has recently been shown to host a non-trivial topological band structure, but is otherwise a paramagnetic metal. However, the other members of the 1-4 family, such as SrAl$_4$ and EuAl$_4$, exhibit symmetry-breaking ground states including charge density wave (CDW) and magnetic order, …

Electronic properties of topological semimetal candidates ACd$_2$Pn$_2$ (A = Eu, Sr; Pn = As, Sb)
Weyl semimetals have attracted significant attention due to their intriguing electronic properties arising from the presence of Weyl points. Among them, ideal magnetic Weyl semimetals, characterized by a single pair of Weyl points close to the Fermi level, have long been sought for exploring the …

Angle-resolved photoemission and first-principles studies of topological semimetals and heterostructures
Topologically nontrivial systems are electronic materials that have protected conducting states on their edge or surface. These widely studied materials are of great interest due to their exotic physical properties and potential for applications in spin-related electronic devices and quantum …

Unidirectional Magnetoresistive Behaviors: Materials, Characterization, and Prospects
… Moreover, BMER is observed in a single layer topological semimetal Pt3Sn for the first time and is found to be enhanced by ~2 times with an adjacent ferromagnetic layer. This finding provides a new approach to manipulating BMER value through opening the band gap of the topological states. This …

A nanoscale probe of the quasiparticle band structure for two dimensional electron systems
… we report on spectroscopic studies of the topological semimetal antimony (Sb). Our simultaneous observation of Landau quantization and quasiparticle interference phenomena on this material enables their quantitative reconciliation - after two decades of their study on various materials. We …

Engineering relativistic fermions in condensed matter systems
… predicted in doped inversion symmetric Weyl semimetals (WSM). Using a four terminal measurement configuration, we show that the nodal points may be shifted and induce a topological phase transition by an application of transverse uniform current in doped WSM. We analyze the topological phase …

Quantum Transport and Electric-Field Effects in Layered Topological Semimetals and Magnetic Materials
… on quantum devices in layered Dirac nodal line topological semimetals and antiferromagnetic materials down to a few layers. We used gate-induced effects to alter the transport properties of these materials. </p> <p>First, we introduced current annealing in topological semimetals to achieve …
