Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

open access: yesSmall, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

Quantum Affine Vertex Algebras Associated to Untwisted Quantum Affinization Algebras

open access: yesCommunications in Mathematical Physics, 2023
Let $\mathcal U_\hbar(\hat{\mathfrak g})$ be the untwisted quantum affinization of a symmetrizable quantum Kac-Moody algebra $\mathcal U_\hbar({\mathfrak g})$. For $\ell\in\mathbb C$, we construct an $\hbar$-adic quantum vertex algebra $V_{\hat{\mathfrak g},\hbar}(\ell,0)$, and establish a one-to-one correspondence between $ϕ$-coordinated $V_{\hat ...

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Is Quantum Field Theory Necessarily “Quantum”?

open access: yesQuantum Reports
The mathematical universe of the quantum topos, which is formulated on the basis of classical Boolean snapshots, delivers a neo-realist description of quantum mechanics that preserves realism.

An Innovative Approach to Multi‐Valued Logic

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Solving Quantum Dynamics with a Lie-Algebra Decoupling Method

open access: yesPRX Quantum
Quantum technologies rely on the control of quantum systems at the level of individual quanta. Mathematically, this control is described by Hamiltonian or Liouvillian evolution, requiring the application of various techniques to solve the resulting ...

Inference‐Sufficient Representations for High‐Throughput Measurement: Lessons from Lossless Compression Benchmarks in 4D‐STEM

open access: yesAdvanced Computing, Volume 1, Issue 1, December 2026.
Agentic workflows will need a principled account of how data relates to scientific inference. We benchmark thirteen off‐the‐shelf compression implementations; the best already sits within 2.5×$\times$ of the entropy bound. We propose inference‐sufficient representations: model‐based representation, employing abductive inference, can reduce storage a ...

A Functorial Construction of Quantum Subtheories

open access: yesEntropy, 2017
We apply the geometric quantization procedure via symplectic groupoids to the setting of epistemically-restricted toy theories formalized by Spekkens (Spekkens, 2016).
