A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Observation of excitons bound by antiferromagnetic correlations
Omar Mehio, Yuchen Han, Xinwei Li +4
Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doubl…
A coherent phonon-induced hidden quadrupolar ordered state in CaRuO
H. Ning, O. Mehio, X. Li +5
Ultrafast laser excitation provides a means to transiently realize long-range ordered electronic states of matter that are hidden in thermal equilibrium. Recently, this approach ha…
A light-induced Weyl semiconductor-to-metal transition mediated by Peierls instability
H. Ning, O. Mehio, C. Lian +7
Elemental tellurium is a strongly spin-orbit coupled Peierls-distorted semiconductor whose band structure features topologically protected Weyl nodes. Using time-dependent density…
Keldysh space control of charge dynamics in a strongly driven Mott insulator
Xinwei Li, Honglie Ning, Omar Mehio +7
The fate of a Mott insulator under strong low frequency optical driving conditions is a fundamental problem in quantum many-body dynamics. Using ultrafast broadband optical spectro…
Signatures of ultrafast reversal of excitonic order in TaNiSe
H. Ning, O. Mehio, M. Buchhold +4
In the presence of electron-phonon coupling, an excitonic insulator harbors two degenerate ground states described by an Ising-type order parameter. Starting from a microscopic Ham…
Magnetic-Field Tuning of Light-Induced Superconductivity in Striped LaBaCuO
D. Nicoletti, D. Fu, O. Mehio +4
Optical excitation of stripe-ordered LaBaCuO has been shown to transiently enhance superconducting tunneling between the CuO planes. This effect was revealed by…
