On the Hamiltonian Bicirculants
Mediterranean Journal of MathematicsAbstract A bicirculant is a regular graph that admits a semi-regular automorphism with two vertex orbits of the same size. By m , we denote the size of vertex orbits and by d the valence of a bicirculant. Furthermore, we denote by

Change in Hamiltonian General Relativity from the Lack of a Time-like Killing Vector Field [PDF]
, 2013 In General Relativity in Hamiltonian form, change has seemed to be missing, defined only asymptotically, or otherwise obscured at best, because the Hamiltonian is a sum of first-class constraints and a boundary term and thus supposedly generates gauge ...

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators
Advanced Materials, EarlyView.A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

Open PhysicsA relativistic transformation of the electrode potential has been derived to account for time dilation effects in electrode processes. This newly formulated Lorentz transformation is interpreted in terms of the generation of spin-2 boson gravitons ...

A new approach to the treatment of Separatrix Chaos and its applications [PDF]
, 2010 We consider time-periodically perturbed 1D Hamiltonian systems possessing one or more separatrices. If the perturbation is weak, then the separatrix chaos is most developed when the perturbation frequency lies in the logarithmically small or moderate ...

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives
Advanced Materials, EarlyView.By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Hamiltonian colorings of graphs with long cycles [PDF]
, 2003 summary:By a hamiltonian coloring of a connected graph $G$ of order $n \ge 1$ we mean a mapping $c$ of $V(G)$ into the set of all positive integers such that $\vert c(x) - c(y)\vert \ge n - 1 - D_G(x, y)$ (where $D_G(x, y)$ denotes the length of a ...

Advanced Materials Technologies, EarlyView.This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Disorder Solutions for Generalized Ising Model with Multispin Interaction
Современные информационные технологии и IT-образование, 2019 This study demonstrates a development of convenient formulae for obtaining the value of the free energy in the thermodynamic limit on a set of exact disorder solutions depending on four parameters for a 2D generalized Ising model in an external magnetic ...
