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}…
Enhanced stochasticity in irradiated vanadium oxide oscillators
Nareg Ghazikhanian, David J. Alspaugh, Pavel Salev +3
Insulator-to-metal transition materials are highly sensitive to even minute deviations of stoichiometry, lattice defects, and disorder, which provides opportunities to engineer the…
Electrically induced negative differential resistance states mediated by oxygen octahedra coupling in manganites for neuronaldynamics
Azminul Jaman, Lorenzo Fratino, Majid Ahmadi +4
The precipitous rise of consumer network applications reiterates the urgency to redefine computing hardware with low power footprint. Neuromorphic computing utilizing correlated ox…
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…
Magnetoresistance anomaly during the electrical triggering of a metal-insulator transition
Pavel Salev, Lorenzo Fratino, Dayne Sasaki +4
Phase separation naturally occurs in a variety of magnetic materials and it often has a major impact on both electric and magnetotransport properties. In resistive switching system…
Characteristic lengthscales of the electrically-induced insulator-to-metal transition
Theodor Luibrand, Adrien Bercher, Rodolfo Rocco +16
Some correlated materials display an insulator-to-metal transition as the temperature is increased. In most cases this transition can also be induced electrically, resulting in vol…
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…
Resistive switching in reverse: voltage driven formation of a transverse insulating barrier
Pavel Salev, Lorenzo Fratino, Dayne Sasaki +6
Application of an electric stimulus to a material with a metal-insulator transition can trigger a large resistance change. Resistive switching from an insulating into a metallic ph…
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…
Antagonistic effects of nearest-neighbor repulsion on the superconducting pairing dynamics in the doped Mott insulator regime

The nearest-neighbor superexchange-mediated mechanism for d_{x^2-y^2}-wave superconductivity in the one-band Hubbard model faces the challenge that nearest-neighbor Coulomb repulsi…
