Summer 2023:
Non-local synaptic interactions discovered in nickelate neuromorphic devices in our latest paper Nano Letters (2023).
Summer 2023:
In collaboration with Eduardo da Silva Neto and Fabio Boschini, our latest paper features low-energy correlations that could be connected to the strange metal phenomenon in the cuprates.
Fall 2022:
A new way of stabilizing 3-dimensional charge order in Pr-substituted YBCO is featured in our latest paper in Nature Communications
Summer 2022:
In our latest paper in Science Advances, we use coherent x-rays to image the formation of antiferromagnetic domains.
Fall 2021:
In our latest paper in Phys. Rev. Materials, we use nano-focused x-rays to study how hydrogenated nickelates behave like synapses in our brain!
Spring 2021:
Alex receives a Cottrell Scholar Award (2021) to create artificial x-ray lattices and develop teaching tools that enhance the creative process.
Winter 2021:
Our latest paper in Nature Communications adds important insight into the origin of charge ordering in the copper-oxide plane of high-Tc supercondcutors, highlighting the role of the Coulomb interaction. This is collaboration with Eduardo da Silva Neto and Fabio Boschini.
Spring 2020:
Our latest result on a quest to create an energy-efficient neuromorphic computer: we have a new hardware implementation of a neural tree using hydrogen-doped nickelate devices, and we image their behavior using nano-focused resonant x rays.
Winter 2020:
Alejandro Ruiz et al. report the existence of a high-temperature magnetic anomaly in a three-dimensional Kitaev candidate.
Winter/Spring 2019:
Our two latest results reveal in-plane diffraction rings in superconducting cuprates: Electrochemically doped La2CuO4+y showing a possible glassy state of the dopant oxygens, and T'-Nd2CuO4 showing charge ordering with a full rotational symmetry. The latter was work done in collaboration with our friends in the Comin Research Lab at MIT.
Summer 2018: U.S. Department of Energy funds an EFRC to study quantum materials for neuromorphic computing.
