Dynamically suppressed lattice rotations in SrTiO as a basis for photo-induced ferroelectricity
Huaiyu Hugo Wang, Michael Fechner, Giovanni De Vecchi +22
Photo-induced ferroelectricity in the quantum paraelectric SrTiO involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural…
Terahertz-induced tunnel ionization drives coherent Raman-active phonon in Bismuth
Bing Cheng, Patrick L. Kramer, Mariano Trigo +6
Driving coherent lattice motion with THz pulses has emerged as a novel pathway for achieving dynamic stabilization of exotic phases that are inaccessible in equilibrium quantum mat…
Terahertz-field activation of polar skyrons
Huaiyu Wang, Vladimir Stoica, Cheng Dai +27
Unraveling collective modes arising from coupled degrees of freedom is crucial for understanding complex interactions in solids and developing new functionalities. Unique collectiv…
Three-dimensional reconstruction of THz near-fields from a LiNbO optical rectification source
Annika E. Gabriel Mohamed A. K. Othman, Patrick L. Kramer, Harumy Miura +2
Terahertz (THz) generation by optical rectification in LiNbO (LN) is a widely used technique for generating intense THz radiation. The spatiotemporal characterization of THz pu…
