We present near-infrared integral field spectroscopy data obtained withVLT/SINFONI of "the Teacup galaxy". The nuclear K-band (1.95-2.45 micron)spectrum of this radio-quiet type-2 quasar reveals a blueshifted broadcomponent of FWHM~1600-1800 km/s in the hydrogen recombination lines(Pa$\alpha$, Br$\delta$, and Br$\gamma$) and also in the coronal line [SiVI]$\lambda$1.963 micron. Thus the data confirm the presence of the nuclearionized outflow previously detected in the optical and reveal its coronalcounterpart. Both the ionized and coronal nuclear outflows are resolved, withseeing-deconvolved full widths at half maximum of 1.1$\pm$0.1 and 0.9$\pm$0.1kpc along PA$\sim$72-74 deg. This orientation is almost coincident with theradio axis (PA=77 deg), suggesting that the radio jet could have triggered thenuclear outflow. In the case of the H$_2$ lines we do not require a broadcomponent to reproduce the profiles, but the narrow lines are blueshifted by~50 km/s on average from the galaxy systemic velocity. This could be anindication of the presence of a nuclear molecular outflow, although the bulk ofthe H$_2$ emission in the inner ~2 arcsec (~3 kpc) of the galaxy follows arotation pattern. We find evidence for kinematically disrupted gas (FWHM>250km/s) at up to 5.6 kpc from the AGN, which can be naturally explained by theaction of the outflow. The narrow component of [Si VI] is redshifted withrespect to the systemic velocity, unlike any other emission line in the K-bandspectrum. This indicates that the region where the coronal lines are producedis not co-spatial with the narrow line region.
