Disorder signatures in coherent electronic waveguides
Alejandro Lopez-Bezanilla
Microscopic disorder in a coherent conductor is encoded in the magnitude of the transmitted current and in the energy- and channel-resolved structure of the scattering response. We…
Moire Control of Alterelectric Quadrupolar Order
Alejandro Lopez-Bezanilla
Alterelectricity is a compensated ferroic state in which quadrupolar electronic order reshapes low-energy electronic structure without producing a net polarization. Here we show th…
Identifying quantum coherence in quantum annealers
Connor Aronoff, Travis Howard, David Nicholaeff +2
Demonstrating genuine many-body quantum coherence in large-scale quantum processors remains a central challenge for near-term quantum technologies. Recent experiments on D-Wave qua…
Programmable Exploration of Magnetic States in Lieb-Kagome Interpolated Lattices
Alejandro Lopez-Bezanilla, Pavel A. Dub, Avadh Saxena
We investigate a hybrid modeling framework in which a quantum annealer is used to simulate magnetic interactions in molecular qubit lattices inspired by experimentally realizable s…
Observation of Magnetic Devil's Staircase-Like Behavior in Quasiperiodic Qubit Lattices
Alejandro Lopez-Bezanilla
The devil's staircase (DS) phenomenon is a fractal response of magnetization to external fields, traditionally observed in periodic ferromagnetic systems, where the commensurabilit…
Quantum dynamics in frustrated Ising fullerenes
Alejandro Lopez-Bezanilla, William Bernoudy, Kelly Boothby +3
The complex energy landscapes exhibited by frustrated magnetic systems undergoing quantum fluctuations are a challenge to accurately simulate, and thus of great interest for testin…
