The material ZrTe5 is a 3D topological insulator that hosts Dirac fermions on the verge of a topological phase transition from a Weak Topological Insulator (WTI) to a Strong Topological Insulator (STI). This transition is driven by external control parameters, such as magnetic fields and strain, and is marked by the presence of exotic topological phenomena, including logarithmic-periodic quantum oscillations, chiral anomaly, anomalous Hall effect, and quasi-quantized Hall effect.

In this work, we map the electronic response of bulk single crystal ZrTe5 as a function of magnetic field, temperature, and strain. Our objective is to reveal a rich phase diagram characterized by a tunable insulator to metal transition and the presence of non-1/B quantum oscillations, which are reminiscent of previously observed logarithmic B-periodic quantum oscillations .

We will discuss our results in the context of how strain, temperature, and magnetic fields can be effectively utilized to adjust low-lying energy scales and electronic bands in topological materials that are close to a topological phase transition.
