Proposal for midinfrared light--induced ferroelectricity in oxide paraelectrics
Alaska Subedi
I show that a nonequilibrium paraelectric to ferroelectric transition can be induced using midinfrared pulses. This relies on a quartic $lQ_{\textrm{l$_z$}}^2Q_{\textrm{h$_x$}}^2$…
Proposal for ultrafast switching of ferroelectrics using mid-infrared pulses
Alaska Subedi
I propose a method for ultrafast switching of ferroelectric polarization using mid-infrared pulses. This involves selectively exciting the highest frequency phonon mode of a…
Low-energy description of the metal-insulator transition in the rare-earth nickelates
Alaska Subedi, Oleg E. Peil, Antoine Georges
We propose a simple theoretical description of the metal-insulator transition of rare-earth nickelates. The theory involves only two orbitals per nickel site, corresponding to the…
A weakly correlated Fermi liquid state with a small Fermi surface in lightly doped SrIrO
Alberto de la Torre, Emily Claire Hunter, Alaska Subedi +7
We characterize the electron doping evolution of (SrLa)IrO by means of angle-resolved photoemission. Concomitant with the metal insulator transition around…
Theory of nonlinear phononics for coherent light-control of solids
Alaska Subedi, Andrea Cavalleri, Antoine Georges
We present a microscopic theory for ultrafast control of solids with high-intensity terahertz frequency optical pulses. When resonant with selected infrared-active vibrations, thes…
