Disorder-driven stochastic dynamics in Mott resistive-switching systems
David J. Alspaugh, Lorenzo Fratino, Nareg Ghazikhanian +2
Controlled disorder in correlated materials provides a new route to emergent stochastic dynamics in neuromorphic hardware. Here we show that focused ion beam irradiation in VO$_{2}…
Coupling strongly correlated electron systems to a tunable electronic reservoir
S. Bag, L. Fratino, A Camjayi +2
We study the effect of coupling an electronic reservoir to a Hubbard model and to a Dimer Hubbard Model. This is motivated by recent experiments on the effect of illumination on th…
Laser-induced quenching of metastability at the Mott-insulator to metal transition
Theodor Luibrand, Lorenzo Fratino, Farnaz Tahouni-Bonab +7
There is growing interest in strongly correlated insulator thin films because the intricate interplay of their intrinsic and extrinsic state variables causes memristive behavior th…
Doping-driven pseudogap-metal-to-metal transition in correlated electron systems
L. Fratino, S. Bag, A. Camjayi +2
We establish that a doping-driven first-order metal-to-metal transition, from a pseudogap metal to Fermi Liquid, can occur in correlated quantum materials. Our result is based on t…
Mott transition and high-temperature crossovers at half-filling
A. Reymbaut, M. Boulay, L. Fratino +4
The interaction-driven Mott transition in the half-filled Hubbard model is a first-order phase transition that terminates at a critical point in the t…
Effects of interaction strength, doping, and frustration on the antiferromagnetic phase of the two-dimensional Hubbard model
L. Fratino, M. Charlebois, P. Sémon +2
Recent quantum-gas microscopy of ultracold atoms and scanning tunneling microscopy of the cuprates reveal new detailed information about doped Mott antiferromagnets, which can be c…
Signatures of the Mott transition in the antiferromagnetic state of the two-dimensional Hubbard model
L. Fratino, P. Sémon, M. Charlebois +2
The properties of a phase with large correlation length can be strongly influenced by the underlying normal phase. We illustrate this by studying the half-filled two-dimensional Hu…
An organizing principle for two-dimensional strongly correlated superconductivity
L. Fratino, P. Sémon, G. Sordi +1
Superconductivity in the cuprates exhibits many unusual features. We study the two-dimensional Hubbard model with plaquette dynamical mean-field theory to address these unusual fea…
Pseudogap and superconductivity in two-dimensional doped charge-transfer insulators
L. Fratino, P. Sémon, G. Sordi +1
High-temperature superconductivity emerges in the CuO plane upon doping a Mott insulator. To ascertain the influence of Mott physics plus short-range correlations, we solve a t…
