Optical signatures of dynamical excitonic condensates
Alexander Osterkorn, Yuta Murakami, Tatsuya Kaneko +3
We theoretically study dynamical excitonic condensates occurring in bilayers with an imposed chemical potential difference and in photodoped semiconductors. We show that optical sp…
Plasmonic polarization sensing of electrostatic superlattice potentials
Shuai Zhang, Jordan Fonseca, Daniel Bennett +15
Plasmon polaritons are formed by coupling light with delocalized electrons. The half-light and half-matter nature of plasmon polaritons endows them with unparalleled tunability via…
Dynamical exciton condensates in biased electron-hole bilayers
Zhiyuan Sun, Yuta Murakami, Tatsuya Kaneko +2
Bilayer materials may support interlayer excitons comprised of electrons in one layer and holes in the other. In experiments, a non-zero exciton density is typically sustained by a…
On the Adequacy of the Dynamical Mean Field Theory for Low Density and Dirac Materials
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
The qualitative reliability of the dynamical mean field theory (DMFT) is investigated for systems in which either the actual carrier density or the effective carrier density is low…
Floquet engineering of many-body states by the ponderomotive potential
Zhiyuan Sun
The ponderomotive force is an effective static force that a particle feels in an oscillating field, whose static potential may be called the ponderomotive potential. We generalize…
Semi-Dirac Fermions in a Topological Metal
Yinming Shao, Seongphill Moon, A. N. Rudenko +14
Topological semimetals with massless Dirac and Weyl fermions represent the forefront of quantum materials research. In two dimensions (2D), a peculiar class of fermions that are ma…
