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…

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…

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…
