Autor: Xingchen Shen, Rolf Heid, Roland Hott, Amir-Abbas Haghighirad, Björn Salzmann, Marli dos Reis Cantarino, Claude Monney, Ayman H. Said, Mehdi Frachet, Bridget Murphy, Kai Rossnagel, Stephan Rosenkranz, Frank Weber

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-10 (2023)

Abstract Research on charge-density-wave (CDW) ordered transition-metal dichalcogenides continues to unravel new states of quantum matter correlated to the intertwined lattice and electronic degrees of freedom. Here, we report an inelastic x-ray scat

Field-induced ultrafast modulation of Rashba coupling at room temperature in ferroelectric α-GeTe(111)

Autor: Geoffroy Kremer, Julian Maklar, Laurent Nicolaï, Christopher W. Nicholson, Changming Yue, Caio Silva, Philipp Werner, J. Hugo Dil, Juraj Krempaský, Gunther Springholz, Ralph Ernstorfer, Jan Minár, Laurenz Rettig, Claude Monney

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-6 (2022)

The ferroelectric material α-GeTe(111) is an excellent playground for spin-to charge conversion due to its strong Rashba coupling. Here, the authors reveal an ultrafast modulation of its Rashba coupling on the femtosecond timescale.

Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNi2B2C

Autor: Philipp Kurzhals, Geoffroy Kremer, Thomas Jaouen, Christopher W. Nicholson, Rolf Heid, Peter Nagel, John-Paul Castellan, Alexandre Ivanov, Matthias Muntwiler, Maxime Rumo, Bjoern Salzmann, Vladimir N. Strocov, Dmitry Reznik, Claude Monney, Frank Weber

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-9 (2022)

Phonon anomalies are commonly attributed to Fermi-surface nesting or phonon anharmonicity, but these mechanisms do not apply in all cases. Here, the authors propose a new mechanism based on electron-momentum-dependent electron-phonon coupling in the

Uniaxial strain-induced phase transition in the 2D topological semimetal IrTe2

Autor: Christopher W. Nicholson, Maxime Rumo, Aki Pulkkinen, Geoffroy Kremer, Björn Salzmann, Marie-Laure Mottas, Baptiste Hildebrand, Thomas Jaouen, Timur K. Kim, Saumya Mukherjee, KeYuan Ma, Matthias Muntwiler, Fabian O. von Rohr, Cephise Cacho, Claude Monney

Publikováno v: Communications Materials, Vol 2, Iss 1, Pp 1-8 (2021)

Uniaxial strain is a powerful approach to tune material properties and select between nearly degenerate phases. Here, uniaxial strain is used to stabilize the elusive 6×1 charge ordered ground state of IrTe2, revealing insights into its electronic s

Long-ranged Cu-based order with $$d_{z^2}$$ d z 2 orbital character at a YBa2Cu3O7/ manganite interface

Autor: Roxana Gaina, Christopher W. Nicholson, Maxime Rumo, Subhrangsu Sarkar, Jarji Khmaladze, Eugenio Paris, Yi Tseng, Wenliang Zhang, Teguh C. Asmara, Daniel McNally, Cinthia Piamonteze, Eugen Weschke, Thorsten Schmitt, Claude Monney, Christian Bernhard

Publikováno v: npj Quantum Materials, Vol 6, Iss 1, Pp 1-8 (2021)

Abstract The interplay of nearly degenerate orders in quantum materials can lead to a myriad of emergent phases. A prominent case is that of the high-T c cuprates for which the relationship between superconductivity and a short-ranged, incommensurate

Electron-lattice interactions strongly renormalize the charge-transfer energy in the spin-chain cuprate Li2CuO2

Autor: Steve Johnston, Claude Monney, Valentina Bisogni, Ke-Jin Zhou, Roberto Kraus, Günter Behr, Vladimir N. Strocov, Jiři Málek, Stefan-Ludwig Drechsler, Jochen Geck, Thorsten Schmitt, Jeroen van den Brink

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)

In transition metal oxides, an insulating band gap is found when the energy scales related to ionic charge excitations dominate over electronic itinerancy. Here, the authors demonstrate strong electron-phonon interactions in Li2CuO2and their effect o
