On the Ground State of Quantum Gravity [PDF]

open access: yesPhysics Letters B, 1998
In order to gain insight into the possible Ground State of Quantized Einstein's Gravity, we have devised a variational calculation of the energy of the quantum gravitational field in an open space, as measured by an asymptotic observer living in an ...

The ground state of the Kondo insulator. [PDF]

open access: yesSci Rep, 2023
AbstractThe Kondo insulator (KI) is the state of an electron liquid in the Kondo lattice at half filling, studied within the mean field approach. We demonstrate, that the $${Z}_2$$ Z 2 -field, which is formed by interaction between electrons and local moments,

Ground state of magnetocrystals [PDF]

open access: yesPhysical 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,

Existence and Asymptotic of Solutions for a $p$-Laplace Schrödinger Equation with Critical Frequency [PDF]

open access: yesSahand 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 ...

The Ground State Electronic Energy of Benzene. [PDF]

open access: yesJournal of Physical Chemistry Letters, 2020
We report on the findings of a blind challenge devoted to determining the frozen-core, full configuration interaction (FCI) ground-state energy of the benzene molecule in a standard correlation-consistent basis set of double-ζ quality.

Graphene ground states [PDF]

open access: yesZeitschrift 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

A Novel Space-Borne High-Resolution SAR System with the Non-Uniform Hybrid Sampling Technology for Space Targets Imaging

open access: yesApplied 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.

Nonreciprocal ground-state cooling of multiple mechanical resonators [PDF]

open access: yesPhysical Review A, 2020
The simultaneous ground-state cooling of multiple degenerate or near-degenerate mechanical modes coupled to a common cavity-field mode has become an outstanding challenge in cavity optomechanics.

The characterization of ground states [PDF]

open access: yesJournal 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.
