Ultrafast dynamics of excitons in black phosphorus
Geoffroy Kremer, Juan F. P. Mosquera, Joël Morf +9
Excitons are key quasiparticles determining the optical properties of solids. As such, they can be utilized to coherently control the electronic structure of materials using optica…
Reversible nanoscale patterning of WTe with a scanning tunneling microscope
Kevin Hauser, Danyang Liu, Berk Zengin +6
Manipulating the lattice structure of ferroelectric quantum materials enables their use in low-power electronic devices, including field-effect transistors. WTe is a Weyl-semim…
Correlated charge order intertwined with time-reversal symmetry-breaking nodal superconductivity in the dual flat band kagome superconductor CeRuSi
O. Gerguri, P. Krà l, M. Spitaler +19
Kagome materials provide a powerful platform for exploring how flat electronic bands promote symmetry-breaking quantum states, yet studies have so far focused mainly on kagome-deri…
Ultrafast recovery dynamics of dimer stripes in IrTe2
M. Rumo, G. Kremer, M. Heber +10
The transition metal dichalcogenide IrTe2 displays a remarkable series of first-order phase transitions below room temperature, involving lattice displacements as large as 20 perce…
Competing Quantum Orders in 6R-TaS: Unconventional Superconductivity, Charge Order, and an Anomalous Hall Effect phase
V. Sazgari, J. N. Graham, S. S. Islam +13
The transition metal dichalcogenide 6R-TaS offers a natural platform for studying the interplay among charge density wave (CDW) order, superconductivity, and transport anomal…
Magnetism in EuAlSi and the Eu1-xSrxAlSi Solid Solution
Dorota I. Walicka, Olivier Blacque, Karolina Gornicka +3
The magnetic properties of EuAlSi, a compound comprising a honeycomb lattice of Al and Si atoms and a triangular lattice of Eu atoms, are presented. Moreover, we have prepared the…
