Ground state on the dumbbell graph [PDF]
Applied Mathematics Research eXpress, 2016 We consider standing waves in the focusing nonlinear Schr\"odinger (NLS) equation on a dumbbell graph (two rings attached to a central line segment subject to the Kirchhoff boundary conditions at the junctions).

A Model Ground State of Polyampholytes [PDF]
Physical Review E, 1998 The ground state of randomly charged polyampholytes is conjectured to have a structure similar to a necklace, made of weakly charged parts of the chain, compacting into globules, connected by highly charged stretched `strings'.

The ground state of three quarks [PDF]
Nuclear Physics B - Proceedings Supplements, 2002 We measure the static three-quark potential in SU(3) lattice gauge theory with improved accuracy, by using all available technical refinements, including Luscher-Weisz exponential variance reduction.

Ground state of magnetocrystals [PDF]
Physical Review E, 2021 Neodyme spherical magnets are inexpensive objects that demonstrate how dipolar particles self-assemble into various structures ranging from 1D chains to 3D crystals. The dipole-dipole interactions confer the stability to these particular architectures. In the present paper, we explore ordered structures only, and we evidence that hybrid magnetocrystals,

Stochastic Mechanism of Shock Disturbances of Rocket Sleigh Supports during High-Speed Track Testing of Aviation Equipment [PDF]
E3S Web of Conferences, 2023 Tests of ballistic aircraft on rail tracks in conditions close to real ones are an economically viable alternative to flight tests. Rocket rail tracks exist in the USA, Canada, France, China and a number of other countries.

Existence and Asymptotic of Solutions for a $p$-Laplace Schrödinger Equation with Critical Frequency [PDF]
Sahand Communications in Mathematical Analysis, 2023 We study the Schr\"odinger equation $\left(\mathrm{Q}_{\varepsilon}\right)$: $- \varepsilon^{2(p-1)} \Delta_p v + V(x)\, |v|^{p-2} v - |v|^{q-1}v = 0$, $x \in \mathbb{R}^N$, with $v(x) \rightarrow 0$ as $|x| \rightarrow+\infty$, for the infinite case ...

Applied Sciences, 2022 In order to reduce the complexity of the receiving system for wideband signals, a novel space-borne high-resolution synthetic aperture radar (SAR) system with the non-uniform hybrid sampling technology is proposed in this paper.

Zeitschrift für angewandte Mathematik und Physik, 2018 Graphene is locally two-dimensional but not flat. Nanoscale ripples appear in suspended samples and rolling-up often occurs when boundaries are not fixed. We address this variety of graphene geometries by classifying all ground-state deformations of the hexagonal lattice with respect to configurational energies including two- and three-body terms. As a

The characterization of ground states [PDF]
Journal of Physics A: Mathematical and Theoretical, 2010 We consider limits of equilibrium distributions as temperature approaches zero, for systems of infinitely many particles, and characterize the support of the limiting distributions. Such results are known for particles with positions on a fixed lattice; we extend these results to systems of particles on R^n, with restrictions on the interaction.

Ground state solutions for periodic Discrete nonlinear Schrödinger equations
AIMS Mathematics, 2021 In this paper, we consider the following periodic discrete nonlinear Schrödinger equation $ \begin{equation*} Lu_{n}-\omega u_{n} = g_{n}(u_{n}), \qquad n = (n_{1}, n_{2}, ..., n_{m})\in \mathbb{Z}^{m}, \end{equation*} $ where $ \omega\notin \sigma(
