Optically driven ultrafast lattice contraction in a topological crystalline insulator
M. H. Berntsen, W. Chen, D. Phuyal +9
The ability to dynamically control topological order remains a central challenge in the exploration of quantum materials. Here, we investigate the lattice and electronic response o…
Roadmap on Quantum Magnetic Materials
Antonija Grubišić-Čabo, Marcos H. D. Guimarães, Dmytro Afanasiev +36
Fundamental research on two-dimensional (2D) magnetic systems based on van der Waals materials has been gaining traction rapidly since their recent discovery. With the increase of…
Exotic Quantum Phenomena in Twisted Bilayer Graphene
Giovanna Feraco, Wissem Boubaker, Petra Rudolf +1
Bilayer graphene twisted at the angle of about 1.1° better known as magic angle, exhibits ultra-flat moiré superlattice bands that are a source of highly-tunable, exotic quantum ph…
Quasi-free-standing AA-stacked bilayer graphene induced by calcium intercalation of the graphene-silicon carbide interface
Antonija Grubišić-Čabo, Jimmy C. Kotsakidis, Yuefeng Yin +11
We study quasi-freestanding bilayer graphene on silicon carbide intercalated by calcium. The intercalation, and subsequent changes to the system, were investigated by low-energy el…
Increasing the Rate of Magnesium Intercalation Underneath Epitaxial Graphene on 6H-SiC(0001)
Jimmy C. Kotsakidis, Marc Currie, Antonija Grubišić-Čabo +9
Magnesium intercalated 'quasi-freestanding' bilayer graphene on 6H-SiC(0001) (Mg-QFSBLG) has many favorable properties (e.g., highly n-type doped, relatively stable in ambient cond…
An efficient low-density grating setup for monochromatization of XUV ultrafast light sources

Ultrafast light sources have become an indispensable tool to access and understand transient phenomenon in material science. However, a simple and easy-to-implement method for harm…
In-situ exfoliation method of large-area 2D materials
Antonija Grubišić-Čabo, Matteo Michiardi, Charlotte E. Sanders +6
The success in studying 2D materials inherently relies on producing samples of large area, and high quality enough for the experimental conditions. Because their 2D nature surface…
A narrow bandwidth extreme ultra-violet light source for time- and angle-resolved photoemission spectroscopy
Qinda Guo, Maciej Dendzik, Antonija Grubišić-Čabo +8
Here we present a high repetition rate, narrow band-width, extreme ultraviolet (XUV) photon source for time- and angle-resolved photoemission spectroscopy (tr-ARPES). The narrow ba…
