A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

Software: Practice and Experience, EarlyView.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Multiple partial integrals of polynomial Hamiltonian systems

, 2021
Se considera sistemele autonome, reale, polinomiale s, i Hamiltoniane de ecuatii diferentiale ordinare. Sunt obtinute unele conditii suficiente de construire a integralelor prime pe baza integralelor particulare polinomiale simple si multiple si sunt identificate sistemele diferentiale ce au astfel de integrale prime.

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

On Tensor-based Polynomial Hamiltonian Systems

It is known that a linear system with a system matrix A constitutes a Hamiltonian system with a quadratic Hamiltonian if and only if A is a Hamiltonian matrix. This provides a straightforward method to verify whether a linear system is Hamiltonian or whether a given Hamiltonian function corresponds to a linear system.

A certainty‐weighted, belief‐based model of political attitudes: A Bayesian analysis of American public attitudes toward the Affordable Care Act

Political Psychology, EarlyView.
Abstract This study proposes a novel, certainty‐weighted account of the process by which political beliefs shape political attitudes. Building upon expectancy‐value frameworks, this paper introduces belief certainty as a moderator of belief impact. A Bayesian partial‐pooling approach is used to test a model positing how beliefs about what the Patient ...

Existence of Full Replica Symmetry Breaking for the Sherrington–Kirkpatrick Model at Low Temperature

Communications on Pure and Applied Mathematics, Volume 79, Issue 7, Page 1746-1770, July 2026.
ABSTRACT We verify the existence of full replica symmetry breaking (FRSB) for the Sherrington–Kirkpatrick (SK) model and determine the structure of its Parisi measure slightly beyond the high temperature regime. More specifically, we prove that the support of the Parisi measure for the SK model consists of an interval starting at the origin slightly ...

Efficient and robust estimation of many-qubit Hamiltonians

Nature Communications
Characterizing the interactions and dynamics of quantum mechanical systems is an essential task in developing quantum technologies. We propose an efficient protocol based on the estimation of the time-derivatives of few qubit observables using polynomial

Coulomb branch algebras via symplectic cohomology

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract Let (M¯,ω)$(\bar{M}, \omega)$ be a compact symplectic manifold with convex boundary and c1(TM¯)=0$c_1(T\bar{M})=0$. Suppose that (M¯,ω)$(\bar{M}, \omega)$ is equipped with a convex Hamiltonian G$G$‐action for some connected, compact Lie group G$G$.

Euler‐Top Gaussian Modes: Structured Beams From Quadratic Angular Momentum Dynamics

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A new family of structured Gaussian light beams are introduced: Euler‐top Gaussian modes. Their ray‐orbital paths on the Gaussian Poincaré sphere correspond to the polhodes of the Euler top in classical angular momentum theory. This geometric and algebraic construction reveals a nonseparable mode family extending the familiar Hermite‐, Laguerre‐ and ...

Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.
