First-order phase transition driven by competing charge-order fluctuations in 1T'-TaTe
S. K. Mahatha, A. Kar, J. Corral-Sertal +20
First-order phase transitions, characterized by a discontinuous change in the order parameter, are intriguing phenomena in condensed matter physics. However, the underlying, materi…
Plasmonic polarons induced by alkali-atom deposition in hafnium disulfide (1-HfS)
Christoph Emeis, Sanjoy Kr Mahatha, Sebastian Rohlf +2
We combine ab-initio calculations based on many-body perturbation theory and the cumulant expansion with angle-resolved photoemission spectroscopy (ARPES) to quantify the electron-…
Quantum spins and hybridization in artificially-constructed chains of magnetic adatoms on a superconductor
Eva Liebhaber, Lisa M. Rütten, Gaël Reecht +5
Magnetic adatom chains on surfaces constitute fascinating quantum spin systems. Superconducting substrates suppress interactions with bulk electronic excitations but couple the ada…
Momentum-space signatures of Berry flux monopoles in a Weyl semimetal
M. Ünzelmann, H. Bentmann, T. Figgemeier +14
Since the early days of Dirac flux quantization, magnetic monopoles have been sought after as a potential corollary of quantized electric charge. As opposed to magnetic monopoles e…
Oxide Fermi liquid universality revealed by electron spectroscopy
M. Horio, K. P. Kramer, Q. Wang +27
We present a combined soft x-ray and high-resolution vacuum-ultraviolet angle-resolved photoemission spectroscopy study of the electron-overdoped cuprate PrLaCe$_…
Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators
Thiago R. F. Peixoto, Hendrik Bentmann, Philipp Rüßmann +27
Since the discovery of the quantum anomalous Hall effect in the magnetically doped topological insulators (MTI) Cr:(Bi,Sb)Te and V:(Bi,Sb)Te, the search for the exc…
Surface states and Rashba-type spin polarization in antiferromagnetic MnBiTe
R. C. Vidal, H. Bentmann, T. R. F. Peixoto +32
The layered van der Waals antiferromagnet MnBiTe has been predicted to combine the band ordering of archetypical topological insulators such as BiTe with the magnet…
Yu-Shiba-Rusinov states in the charge-density modulated superconductor NbSe2
Eva Liebhaber, Sergio Acero Gonzalez, Rojhat Baba +6
NbSe is a remarkable superconductor in which charge-density order coexists with pairing correlations at low temperatures. Here, we study the interplay of magnetic adatoms and t…
