Universal magnetic energy scale in the doped Fermi-Hubbard model
Radu Andrei, Ivan Morera, Jonathan B. Curtis +2
Magnetic correlations of doped Mott insulators hold the key to the unusual characteristics of many quantum materials. Recent experiments with ultracold atoms in optical lattices ha…
Toward the Thermodynamic Limit: Neural Operators for Non-equilibrium Dynamics of Mott Insulators
Miles Waugh, Chuwei Wang, Radu Andrei +4
Mott insulators exhibit complex photoexcitation dynamics under intense optical driving, with potential implications for carrier multiplication beyond the Shockley-Queisser limit. P…
Subgap pumping of antiferromagnetic Mott insulators: photoexcitation mechanisms and applications
Radu Andrei, Mingyao Guo, Mustafa Ali +4
We study the behavior of the 2D repulsive Hubbard model on a square lattice at half filling, under strong driving with ac electric fields, by employing a time-dependent Gaussian va…
Photoengineering the Magnon Spectrum in an Insulating Antiferromagnet
V. Radovskaia, R. Andrei, J. R. Hortensius +9
Femtosecond optical pulses have opened a new frontier in ultrafast dynamics, enabling direct access to fundamental interactions in quantum materials. In antiferromagnets (AFMs), wh…
