Unraveling the symmetry of Al5C3N
Vitalii Shtender, Chin Shen Ong, Pedro Berastegui +6
The high-temperature ceramic compound Al5C3N with promising application usage belongs to the scarcely studied Al-C-N system. It was originally reported as an ordered compound in th…
Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
How quantum selection rules influence the magneto-optical effects of driven, ultrafast magnetization dynamics
Mohamed F. Elhanoty, Olle Eriksson, Chin Shen Ong +1
Ultrafast magnetization dynamics driven by ultrashort pump lasers is typically explained by changes in electronic populations and scattering pathways of excited conduction electron…
Photo-induced Hidden Phase of 1T-TaS2 with Tunable Lifetime
Pierre-Adrien Mante, Chin Shen Ong, Daniel Finkelstein Shapiro +3
Phase transitions are ubiquitous, appearing at every length scale from atoms to galaxies. In condensed matter, ultrafast laser pulses drive materials to highly non-equilibrium cond…
