The optical phonoelectric effect
D. Choi, M. Först, M. Fechner +9
Piezoelectricity is a technologically important property of certain insulators in which mechanical strain induces an electrical polarization. However, the rate at which a piezoelec…
Signatures of three-dimensional photo-induced superconductivity in YBaCuO
M. Rosenberg, D. Nicoletti, M. Buzzi +5
Optical excitation of large-amplitude apical oxygen phonon oscillations has been shown to renormalize the electronic properties of YBaCuO, inducing a superconductin…
Enhanced coherent terahertz emission from critical superconducting fluctuations in YBaCuO
D. Nicoletti, M. Rosenberg, M. Buzzi +10
Coherent terahertz (THz) emission is emerging as a powerful new tool to probe symmetry breakings in quantum materials. This method relies on second order optical nonlinearities and…
Re-entrant unconventional superconductivity induced by rare-earth substitution in Nd1-xEuxNiO2 thin films
Dung Vu, Hangoo Lee, Daniele Nicoletti +17
High temperature superconductivity is typically associated with strong coupling and a large superconducting gap, yet these characteristics have not been demonstrated in the nickela…
Tunable narrowband THz generation in the organic crystal BNA
D. Pavicevic, M. Nishida, J. Song +2
The generation of tunable narrowband pulses is increasingly being pursued in terahertz science, for example to study the nonlinear response of individual modes of solids and molecu…
Cavity-altered superconductivity
Itai Keren, Tatiana A. Webb, Shuai Zhang +30
Is it feasible to alter the ground state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions, experimental realizations of…
