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,…
Spectroscopic view of ultrafast charge carrier dynamics in single- and bilayer transition metal dichalcogenide semiconductors
P. Majchrzak, K. Volckaert, A. G. Cabo +24
The quasiparticle spectra of atomically thin semiconducting transition metal dichalcogenides (TMDCs) and their response to an ultrafast optical excitation critically depend on inte…
Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
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…
Weyl-like points from band inversions of spin-polarised surface states in NbGeSb
I. Marković, C. A. Hooley, O. J. Clark +16
Band inversions are key to stabilising a variety of novel electronic states in solids, from topological surface states in inverted bulk band gaps of topological insulators to the f…
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…
A general route to form topologically-protected surface and bulk Dirac fermions along high-symmetry lines

The band inversions that generate the topologically non-trivial band gaps of topological insulators and the isolated Dirac touching points of three-dimensional Dirac semimetals gen…
