Odd-frequency pair correlations in the trapped fermionic Tonks-Girardeau gas
M. Wong, K. Thompson, M. Governale +2
The fermionic Tonks-Girardeau gas is an exactly solvable model realizing a conventional macroscopic condensate of p-wave Cooper pairs. Here we demonstrate that, when confined by a…

Ultrafast non-thermal suppression of ferroelectricity by carrier screening in LiNbO3
Man Tou Wong, Zhuquan Zhang, Zi-Jie Liu +1
Ferroelectric materials are key to energy-efficient electronics, memory, and optical applications. While charge carriers typically screen and suppress ferroelectricity, their role…

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…
