Infrared evidence for strong symmetry breaking in 1-TiSe
Esther van Grondelle, Kai Rossnagel, Jasper van Wezel +1
The interplay between lattice and electron degrees of freedom gives rise to competing ordered states in quantum materials, which can lead to a series of subsequent symmetry breakin…
Near-field imaging of domain switching in in-operando VO devices
Sergio Salvía Fernández, Xing Gao, Silvia Cassanelli +3
Experimental insight in the nanoscale dynamics underlying switching in novel memristive devices is limited owing to the scarcity of techniques that can probe the electronic structu…
Hydrodynamics of plastic deformations in electronic crystals
Jay Armas, Erik van Heumen, Akash Jain +1
We construct a new hydrodynamic framework describing plastic deformations in electronic crystals. The framework accounts for pinning, phase, and momentum relaxation effects due to…
Strange metal dynamics across the phase diagram of BiSrCuO cuprates
Erik van Heumen, Xuanbo Feng, Silvia Cassanelli +7
Unlocking the mystery of the strange metal state has become the focal point of high T research, not because of its importance for superconductivity, but because it appears to…
Momentum-dependent scaling exponents of nodal self-energies measured in strange metal cuprates and modelled using semi-holography
S. Smit, E. Mauri, L. Bawden +13
The anomalous strange metal phase found in high- cuprates does not follow the conventional condensed-matter principles enshrined in the Fermi liquid and presents a great chall…
Observation of the charge density wave collective mode in the infrared optical response of VSe
Xuanbo Feng, Jans Henke, Corentin Morice +4
We present a detailed study of the bulk electronic structure of high quality VSe single crystals using optical spectroscopy. Upon entering the charge density wave phase below…
Incoherent transport across the strange metal regime of highly overdoped cuprates
J. Ayres, M. Berben, M. Culo +11
Strange metals possess highly unconventional transport characteristics, such as a linear-in-temperature () resistivity, an inverse Hall angle that varies as and a linear-i…
Scattering rate collapse driven by a van Hove singularity in the Dirac semi-metal PdTe
Erik van Heumen, Maarten Berben, Linda Neubrand +1
We present optical measurements of the transition metal dichalcogenide PdTe. The reflectivity displays an unusual temperature and energy dependence in the far-infrared, which…
Electronic structure of the candidate 2D Dirac semimetal SrMnSb2: a combined experimental and theoretical study
S. V. Ramankutty, J. Henke, A. Schiphorst +15
SrMnSb is suggested to be a magnetic topological semimetal. It contains square, 2D Sb planes with non-symmorphic crystal symmetries that could protect band crossings, offering…
From bad metal to Kondo insulator: temperature evolution of the optical properties of SmB
A. Tytarenko, K. Nakatsukasa, Y. K. Huang +2
The recent rekindling of interest in the mixed valent Kondo insulator SmB as candidate for a first correlated topological insulator has resulted in a wealth of new experiment…
Direct observation of a Fermi liquid-like normal state in an iron-pnictide superconductor
Alona Tytarenko, Yingkai Huang, Anne de Visser +2
There are two prerequisites for understanding high-temperature (high-T) superconductivity: identifying the pairing interaction and a correct description of the normal state fro…
Angle-resolved and core-level photoemission study of interfacing the topological insulator Bi1.5Sb0.5Te1.7Se1.3 with Ag, Nb and Fe
N. de Jong, E. Frantzeskakis, B. Zwartsenberg +7
Interfaces between a bulk-insulating topological insulator (TI) and metallic adatoms have been studied using high-resolution, angle-resolved and core-level photoemission. Fe, Nb an…
Hard x-ray photoemission and density functional theory study of the internal electric field in SrTiO3/LaAlO3 oxide heterostructures
E. Slooten, Zhicheng Zhong, H. J. A. Molegraaf +16
A combined experimental and theoretical investigation of the electronic structure of the archetypal oxide heterointerface system LaAlO3 on SrTiO3 is presented. High-resolution, har…
