Abstract:
Recent developments in attosecond technology led to table-top x-ray spectroscopy in the soft x-ray range, thus uniting the element- and state-specificity of core-level x-ray absorption spectroscopy with the time resolution to follow electronic dynamics…

Nature Chemistry volume 13pages420–427 (2021)

Abstract:
Molecular Russian dolls (matryoshkas) have proven useful for testing the limits of preparative supramolecular chemistry but applications of these architectures to problems in other fields are elusive. Here we report a three-shell…

Nano Lett. 2021, 21, 11, 4577–4583

Abstract:
Light sources on the scale of single molecules can be addressed and characterized at their proper sub-nanometer scale by scanning tunneling microscopy-induced luminescence (STML). Such a source can be driven by defined short charge…

1D charge density wave in the hidden order state of URu2Si2

1D charge density wave in the hidden order state of URu2Si2

Author: Edwin Herrera, Víctor Barrena, Isabel Guillamón, José Augusto Galvis, William J. Herrera, José Castilla, Dai Aoki, Jacques Flouquet & Hermann Suderow

Communications Physics. volume 4, Article number: 98 (2021

Abstract:
Single crystals of URu2Si2 show below 17.5 K a transition into an ordered state with a significantly reduced entropy. The low temperature phase is called the hidden order (HO) state, because its microscopic origin is still unknown—there are no charge….
