The fate of topological properties in U-based materials*

Recent reports on CeSbTe show that Weyl and Dirac topological states can be tuned by low magnetic fields, which provide a promising route for investigating the interplay between magnetism and topology [1]. Here we aim at increasing the degree of correlations in this system by replacing Ce with U atoms. Though USbTe has been investigated previously [2,3], little is known about its putative topological properties. In this talk, I will discuss the growth of USbTe single crystals and their physical properties characterization via thermodynamic and electrical transport measurements at ambient pressure and under applied pressure.
