Hamiltonian cycles in generalized petersen graphs

open access: yesJournal of Combinatorial Theory, Series B, 1978
AbstractWatkins (J. Combinatorial Theory 6 (1969), 152–164) introduced the concept of generalized Petersen graphs and conjectured that all but the original Petersen graph have a Tait coloring. Castagna and Prins (Pacific J. Math. 40 (1972), 53–58) showed that the conjecture was true and conjectured that generalized Petersen graphs G(n, k) are ...

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

open access: yesAdvanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

open access: yesAdvanced Quantum Technologies, EarlyView.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Band Edge Reorganization via Symmetry Constraints in Covalent Bonding Heterojunctions Boosts Photocatalytic Metronidazole Degradation

open access: yesRare Metals, EarlyView.
ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

Influence of Asymmetry on the Molecular and Electronic Structures of μ‐Oxo Diferric Complexes

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The 6‐methyl substituents at the pyridines (shown in red) enforce longer MNpy bonds than without them (shown in green).The asymmetric dinucleating susanH2Me2 is used for the synthesis of a μ‐oxo diferric complex. Comparison to the two symmetric complexes of susan and susan6−Me shows a strong effect on the redox potentials.

Dynamic Pricing With Recommendation and Consumer Feedback

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT A long‐lived seller sells a new product of unknown value by offering prices and recommendations to short‐lived consumers in continuous time. The seller receives consumer feedback about the product at a rate that increases with the instantaneous sales volume.
