Ultrafast electron control⚡️
In our new Nature Communications paper, we switch single-atom charge states in WSe₂ with picosecond THz pulses—capturing atomic-scale ultrafast dynamics.

📢 We report optimized on-surface synthesis of 17-atom-wide armchair graphene nanoribbons reaching ~17 nm average length. Gradual annealing and high surface coverage enable length enhancement and stability under ambient and harsh conditions.

Congratulations to our PhD student, Laric Bobzien, for winning the 2025 EPS-QEOD / Young Minds Best Student Presentation Award! Laric works in our Terahertz lab, focusing on ultrafast scanning probe microscopy of atomic quantum emitters in 2D materials.
The CarboQuant project at @Empa_CH is set to enter the next phase—thanks to a new, highly specialised laboratory. Researchers now have the capacity to study and manipulate the quantum magnetic states of their carbon materials with even greater precision.

"Quantum Lego": We engineered spin-1/2 Heisenberg chains by linking Olympicene nanographenes, unveiling their length-dependent spin excitations. With STM/IETS, we confirm gapless behavior in the thermodynamic limit & visualize spinon standing waves.
New Empa lab, CarboQuant, set to harness #quantum effects from #carbon, opening the way for sustainable quantum technologies.

In our latest work, we show a sub-exponential increase in charge-state lifetime of Se vacancies in WSe₂, from picoseconds in monolayers to nanoseconds in multilayers. Great collaboration with @PennStateMatSE !
