Revealing the anisotropic charge-density-wave order of TiSe$_2$ through high harmonic generation Open
Titanium diselenide (TiSe$_{2}$) is a transition-metal dichalcogenide material that undergoes a charge-density-wave (CDW) transition at $T_{c}\approx 200\,\mathrm{K}$. In a recent experiment [I. Tyulnev {\it et al.}, Commun. Mater. 6, 152 …

High harmonic spectroscopy reveals anisotropy of the Mott to Charge-Density-Wave phase transition in TiSe$_2$ Open
This work explores the use of polarization-resolved high harmonic generation (HHG) spectroscopy to investigate the quantum phases and transitions in the correlated charge density wave (CDW) phase of TiSe$_2$. Unlike previous studies focusi…

Polarization-Shaped Strong Field Control Over Valley Polarization with Mid-IR Light Open
We induce valley-control in MoS 2 with a polarization-shaped mid-infrared light field. The trefoil-shaped pump field is characterized by high harmonic spectroscopy and valley polarization is read our by a probe field via second harmonic ge…

Polarization-Shaped Strong Field Control over Valley Polarization with Mid-IR Light Open
We induce control over valley polarization with a polarization-shaped mid-infrared light field. The polarization state of the trefoil-shaped pump fields is measured by high harmonic spectroscopy, which we also use to confirm strong field c…

Frequency dependence of the Kerr constant in Nynas Nytro 3000 oil determined by the polarimetric method Open
frequency dependence of the Kerr constant K in transformer oil Nynas Nytro 3000 within a frequency range 117-5017 Hz is determined. An averaged value (2.30 ± 0.03)·10-15 m/V2 for K is obtained. The constant is found to be weakly frequency …
