Nature of the current-induced insulator-to-metal transition in CaRuO as revealed by transport-ARPES
Cissy T Suen, Igor Marković, Marta Zonno +21
The Mott insulator CaRuO exhibits a rare insulator-to-metal transition (IMT) induced by DC current. While structural changes associated with this transition have been track…
A spatially resolved optical method to measure thermal diffusivity
F. Sun, S. Mishra, P. H. McGuinness +8
We describe an optical method to directly measure position-dependent thermal diffusivity of reflective single crystal samples across a broad range of temperatures for condensed mat…
Hierarchy of Lifshitz transitions in the surface electronic structure of SrRuO under uniaxial compression
Edgar Abarca Morales, Gesa-R. Siemann, Andela Zivanovic +12
We report the evolution of the electronic structure at the surface of the layered perovskite SrRuO under large in-plane uniaxial compression, leading to anisotropic $B_{1g}…
Orbital-selective Band Hybridisation at the Charge Density Wave Transition in Monolayer TiTe
T. Antonelli, W. Rahim, M. D. Watson +12
An anomalous charge density wave (CDW) phase emerges in monolayer 1T-TiTe which is absent for the bulk compound, and whose origin is still poorly understood. Here,…
Electronically driven spin-reorientation transition of the correlated polar metal CaRuO
I. Marković, M. D. Watson, O. J. Clark +11
Polar distortions in solids give rise to the well-known functionality of switchable macroscopic polarisation in ferroelectrics and, when combined with strong spin-orbit coupling, c…
Direct Observation of a Uniaxial Stress-driven Lifshitz Transition in SrRuO
V. Sunko, E. Abarca Morales, I. Marković +11
Pressure represents a clean tuning parameter for traversing the complex phase diagrams of interacting electron systems and as such has proved of key importance in the study of quan…
Probing spin correlations using angle resolved photoemission in a coupled metallic/Mott insulator system
V. Sunko, F. Mazzola, S. Kitamura +16
A nearly free electron metal and a Mott insulating state can be thought of as opposite ends of possibilities for the motion of electrons in a solid. In the magnetic oxide metal PdC…
Orbital- and -selective hybridisation of Se 4p and Ti 3d states in the charge density wave phase of TiSe
Matthew D. Watson, Oliver J. Clark, Federico Mazzola +5
We revisit the enduring problem of the charge density wave (CDW) order in TiSe, utilising photon energy-dependent angle-resolved photoemission spectroscop…
Itinerant ferromagnetism of the Pd-terminated polar surface of PdCoO
F. Mazzola, V. Sunko, S. Khim +9
We study the electronic structure of the Pd-terminated surface of the non-magnetic delafossite oxide metal PdCoO. Combining angle-resolved photoemission spectroscopy and densit…
