Heuristic Estimation of the Vacuum Energy Density of the Universe: Part II-Analysis Based on Frequency Domain Electromagnetic Radiation
In Part I of this paper, an inequality satisfied by the vacuum energy density of the universe was derived using an indirect and heuristic procedure. The derivation is based on a proposed thought experiment, according to which an electron is accelerated to ...
2024Universal Casimir attraction between filaments at the cell scale
Anne-Florence Raphaëlle Bitbol
The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long-ranged. Here, we study the geometry of two parallel dielectric cylinders. W ...
Bristol2024A generalization of the Hawking black hole area theorem
Hawking's black hole area theorem was proven using the null energy condition (NEC), a pointwise condition violated by quantum fields. The violation of the NEC is usually cited as the reason that black hole evaporation is allowed in the context of semiclass ...
Springer/Plenum Publishers2024Heuristic Estimation of the Vacuum Energy Density of the Universe: Part I—Analysis Based on Time Domain Electromagnetic Radiation
Marcos Rubinstein, Farhad Rachidi-Haeri
In this paper, an inequality satisfied by the vacuum energy density of the universe is derived using an indirect and heuristic procedure. The derivation is based on a proposed thought experiment, according to which an electron is accelerated to a constant ...
2023Beyond - ?CDM constraints from the full shape clustering measurements from BOSS and eBOSS
We analyse the full shape of anisotropic clustering measurements from the extended Baryon Oscillation Spectroscopic Survey quasar sample together with the combined galaxy sample from the Baryon Oscillation Spectroscopic Survey. We obtain constraints on the ...
OXFORD UNIV PRESS2023Covariance matrices for variance-suppressed simulations
Cosmological N-body simulations provide numerical predictions of the structure of the Universe against which to compare data from ongoing and future surveys, but the growing volume of the Universe mapped by surveys requires correspondingly lower statistica ...
OXFORD UNIV PRESS2022Edge-Contact MoS2 Transistors Fabricated Using Thermal Scanning Probe Lithography
Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio
The science and engineering of two-dimensional materials (2DMs), in particular, of 2D semiconductors, is advancing at a thriving pace. It is well known that these delicate few-atoms thick materials can be damaged during the processing toward their integrat ...
AMER CHEMICAL SOC2022Linearized supergravity with a dynamical preferred frame
We study supersymmetric extension of the Einstein-aether gravitational model where local Lorentz invariance is broken down to the subgroup of spatial rotations by a vacuum expectation value of a timelike vector field called aether. Embedding aether into a ...
SPRINGER2021Spontaneous conformal symmetry breaking in fishnet CFT
Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: their vacuum energy (cosmological constant) is equal to zero. Up to now, the only known ultraviolet complete theories where conformal symmetry can b ...
ELSEVIER2020Machine learning models of the energy curvature vs particle number for optimal tuning of long-range corrected functionals
Alberto Fabrizio, Benjamin André René Meyer
The average energy curvature as a function of the particle number is a molecule-specific quantity, which measures the deviation of a given functional from the exact conditions of density functional theory. Related to the lack of derivative discontinuity in ...
