Classical and quantum phase transitions (QPTs), with their accompanying concepts of criticality and universality, are a cornerstone of statistical thermodynamics. An excellent example of a controlled QPT is the field-induced ordering of a gapped quan

We present a route to grow single crystals of Ba 0.9 Sr 0.1 CuSi 2 O 6 suitable for inelastic neutron studies via the floating zone technique. Neutron single crystal diffraction was utilized to check their bulk quality and orientation. Finally, the h

The dimerized quantum magnet ${\mathrm{BaCuSi}}_{2}{\mathrm{O}}_{6}$ was proposed as an example of ``dimensional reduction'' arising near the magnetic-field-induced quantum critical point (QCP) due to perfect geometrical frustration of its interbilay

We generate frequency-tunable narrow-band intense fields in the terahertz (THz) range by optical rectification of a temporally modulated near-infrared laser pumping a nonlinear organic crystal. Carrier-frequency tunability between 0.5 and 6.5THz is a
