Light-induced trion-exciton competition revealed by ultrafast photoemission
Ittai Sidilkover, Nir Hen Levin, Yuval Nitzav +11
Strong Coulomb interactions in low-dimensional quantum materials give rise to emergent bound states such as excitons and trions. Trions are conventionally secondary excitations, re…
Magnetization Plateaux as a Roadmap to Quantum Spin Liquids
Anna Keselman, Xinyuan Xu, Hao Zhang +2
We investigate the spin-1/2 triangular-lattice Heisenberg antiferromagnet in a magnetic field by combining large-scale density matrix renormalization group (DMRG) simulat…
Trion gas on the surface of a failed excitonic insulator
Yuval Nitzav, Abigail Dishi, Himanshu Lohani +15
Trions, three-body bound states composed of an exciton and an additional charge, are typically fragile and require external excitation to form. Here, we report the spontaneous emer…
A Unifying Framework for Fractional Chern Insulator Stabilization
Peleg Emanuel, Anna Keselman, Yuval Oreg
We present a theory of fractional Chern insulator stabilization against charge-ordered states. We argue that the phase competition is captured by an effective interaction range, wh…
Spin Seebeck effect of interacting spinons
Ren-Bo Wang, Naveen Nishad, Anna Keselman +2
We present the theory of the longitudinal spin Seebeck effect between a Heisenberg spin-1/2 chain and a conductor. The effect consists of the generation of a spin current across th…
Discovery of a topological exciton insulator with tunable momentum order
Md Shafayat Hossain, Tyler A. Cochran, Yu-Xiao Jiang +27
Correlated topological materials often maintain a delicate balance among physical symmetries: many topological orders are symmetry protected, while most correlated phenomena arise…
