About me...

I'm Lucas J. Fernández-Alcázar, I'm a Researcher at the Institute of Modelling and Innovation on Technology (IMIT-CONICET) in Corrientes, Argentina.

I completed my Ph.D. in 2016 at the National University of Cordoba, Cordoba, Argentina under the advice of Horacio M. Pastawski,  where I studied the spin-dependent Quantum transport and quantum dynamics of electrons and how they are affected by a decoherent environment.

Next, I did a postdoc in the same institution, in collaboration with Raul Bustos-Marun, where I studied Adiabatic Quantum Motors, which are highly-efficient nanomachines powered by electronic currents, and how their dynamics and performance are affected by decoherence.

After that, in 2018 I moved to the USA to do a postdoc with Tsampikos Kottos at Wesleyan University, where I shifted my area of research to Photonics, where we designed devices to control thermal radiative energy currents through time modulated photonic circuits.

Finally, I moved to Corrientes, Argentina at the end of 2020, where I got a position as Assistant Researcher at the Institute of Modelling and Innovation on Technology (IMIT-CONICET) and Northeastern National University.

My research interest lies in the interface between Condensed Matter, Quantum Mechanics, and Photonics. Specifically, I'm interested in the transport of wavelike excitations (electrons, photons, phonons, etc. ) in the micro and nanoscale in complex systems.

Noise Resilient Nonlinear Exceptional-Point Sensors

By using a nonlinear PT circuit that presents an exceptional point degeneracy (EPD), we develop an extremely sensitive sensor which in turn is robust against noise. Our results resolve a long-standing debate on the efficacy of EPD-sensing in active systems above self-oscillating threshold.

Optical phase transitions in multimoded photonic networks

We investigate the collective dynamics of nonlinearly interacting modes in multimode photonic settings. Our analysis sheds light on the nature of the thermal equilibrium states and reveals the existence of optical phase transitions which resemble a paramagnetic to a ferromagnetic and to a spin-glass phase transition occurring in spin networks.
