Between famine and freedom: Food prices during the Indonesian War of Independence, 1945–9

The Economic History Review, EarlyView.
Abstract This paper investigates how the Indonesian War of Independence (1945‒9) influenced staple food prices, and how fluctuations in those prices, in turn, shaped the trajectory and dynamics of the conflict. We compiled a dataset comprising more than 8600 prices for staple foods covering the entire Indonesian archipelago from 1939‒49, allowing us to

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

Journal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

Liouville-Fock-state lattices: From environment-induced frustration to synthetic lattice dynamics

Physical Review Research
We introduce Liouville-Fock-state lattices (LFSLs) as a framework for visualizing open quantum systems through matrix representations of the Lindblad master equation.

Tensor Hypercontraction Error Correction Using Regression

Journal of Computational Chemistry, Volume 47, Issue 8, 30 March 2026.
The combination of tensor hypercontraction with machine learning bridges the gap between accuracy and computational efficiency through scaling reduction. ABSTRACT Wavefunction‐based quantum methods are some of the most accurate tools for predicting and analyzing the electronic structure of molecules, in particular for accounting for dynamical electron ...

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 5, 18 March 2026.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.

DFTB Parametrization at the Example of Platinum—Implementation, Validation and Practical Considerations

Journal of Computational Chemistry, Volume 47, Issue 7, March 15, 2026.
Development and comprehensive validation of 3ob‐compatible DFTB3 parameters for platinum, enabling efficient and reliable simulations of a wide range of Pt‐containing systems. ABSTRACT Practical considerations for the parametrization of the transition metal platinum within the third‐order density‐functional tight‐binding (DFTB3) method are presented ...

Quantum Error Correction beyond SU(2): Spin, Bosonic, and Permutation-Invariant Codes from Convex Geometry

PRX Quantum
We develop a framework for constructing quantum error-correcting codes and logical gates for three types of spaces—composite permutation-invariant spaces of many qubits or qudits, composite constant-excitation Fock state spaces of many bosonic modes, and

Heat and Laplace type equations with complex spatial variables in weighted Fock spaces

Electronic Journal of Differential Equations, 2020
In a recent book co-authored by the authors of this article, we studied by semigroup theory methods several classical evolution equations, including the heat and Laplace equations, with real time variable and complex spatial variable, under the ...

The Mehler-Fock Transform in Signal Processing

Entropy, 2017
Many signals can be described as functions on the unit disk (ball). In the framework of group representations it is well-known how to construct Hilbert-spaces containing these functions that have the groups SU(1,N) as their symmetry groups.

Unphysical Structure Collapse in Quantum Mechanics Calculations With Continuum Solvation

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.
Quantum mechanics conformer searches with continuum solvation models yield preferably collapsed conformations not confirmed by sophisticated nuclear magnetic resonance (NMR) experiments. Continuum solvation force‐field and explicit solvation molecular dynamics simulations result preferably in stretched conformations, hinting on general weaknesses of ...
