Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Symbolic Quantum Simulation with Quasimodo

, 2023
AbstractThe simulation of quantum circuits on classical computers is an important problem in quantum computing. Such simulation requires representations of distributions over very large sets of basis vectors, and recent work has used symbolic data-structures such as Binary Decision Diagrams (BDDs) for this purpose.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Spatially‐Resolved Coherence of Organic Molecular Spins at Room‐Temperature

Advanced Functional Materials, EarlyView.
Molecular spin qubits are emerging as a promising quantum sensing technology. This paper studies the variation in coherence and sensitivity in both crystalline and thin‐film samples by combining microscopy and room temperature optically detected coherent control.

Controlling Proton Migration in Oxide Heterostructures by Interfacial Chemical Potential Mismatch

Advanced Functional Materials, EarlyView.
Interfacial reconstruction of the proton chemical potential enables control of proton migration in oxide heterostructures. In TiO2/VO2 heterostructures, we found that increasing the TiO2 capping layer thickness by only several nanometers modulates the thermal stability of protons inserted into VO2.
