Stephan Allenspach received the SNSS Young Scientists Prize

Congratulations to Stephan Allenspach for receiving the Young Scientist Prize of the Swiss Neutron Scattering Society for his outstanding PhD thesis.

Stephan did his PhD in the Quantum Criticality and Dynamics Group lead by Christian Rüegg. During his PhD, he investigated the many body quantum physics of the quasi-2D spin-dimer compounds BaCuSi₂O₆ and Ba_0.9Sr_0.1CuSi₂O₆. For this, he used a combination of neutron scattering experiments (carried out at SINQ and other large-scale facilities), theoretical modeling of the inelastic neutron scattering intensity of spin-dimer systems, and modern statistical methods for the determination of critical exponents from phase boundaries.
