Quadrature Based Neural Network Learning of Stochastic Hamiltonian Systems

Mathematics
Hamiltonian Neural Networks (HNNs) provide structure-preserving learning of Hamiltonian systems. In this paper, we extend HNNs to structure-preserving inversion of stochastic Hamiltonian systems (SHSs) from observational data.

Faddeev equation and its symmetric version for a three-particle lattice hamiltonian [PDF]

E3S Web of Conferences
In the present paper we consider the three-particle lattice Hamiltonian associated to a system of three particles on the d-dimensional lattice, where the role of two-particle discrete Schroedinger operators is played by a family of Friedrichs models.

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

Advanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Interface Structures and Hamiltonians: Exact Results

International Journal of Thermophysics, 2001
There have been many recent applications of interface models and Hamiltonians to problems in the theory of wetting. These models help to understand more abstract calculations on the type of problem which can be treated on the one hand, and on the other, to extend the type of problem which can be treated. A very recent example of this is corner wetting,

Proximity Induced Magnetic Anisotropy and Trefoil Fermiology in Monolayer FeCl2/Bi(111)

Advanced Materials, EarlyView.
Reorientation of magnetic anisotropy in a 2D van der Waals magnet is demonstrated in monolayer FeCl2 epitaxially grown on a bismuth substrate, from its natural out‐of‐plane direction to a predominantly in‐plane orientation. The FeCl2/bismuth heterostructure exhibits moiré‐induced interface states, suggesting strong coupling at the interface.

Quantum Electrometry of Non‐Volatile Space Charges in Diamond

Advanced Optical Materials, EarlyView.
Charges are generated when nitrogen vacancy qubits in diamond are illuminated by light. Transport and trapping in an electric field leads to the formation of large, stable space charge patterns that dynamically screen applied electric fields, impacting electric field sensing and photoelectric detection.

An Integrated Integrable Hierarchy Arising from a Broadened Ablowitz–Kaup–Newell–Segur Scenario

Axioms
This study introduces a 4×4 matrix eigenvalue problem and develops an integrable hierarchy with a bi-Hamiltonian structure. Integrability is ensured by the zero-curvature condition, while the Hamiltonian structure is supported by the trace identity ...

Duality relation among the Hamiltonian structures of a parametric coupled Korteweg-de Vries system

Open Physics, 2016
We obtain the full Hamiltonian structure for a parametric coupled KdV system. The coupled system arises from four different real basic lagrangians. The associated Hamiltonian functionals and the corresponding Poisson structures follow from the geometry ...

Energy Consumption Optimization in Trajectory Planning for Fuel Cell Hybrid Uavs Based On HMPC

Advanced Robotics Research, EarlyView.
The endurance limitation of multirotor drones is a critical challenge. This study adopts a hybrid power system of fuel cells and lithium‐ion batteries. Using Nondominated Sorting Genetic Algorithm II, it integrates trajectory planning with energy management optimization.

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.
