Collapse of Vacuum Bubbles in a Vacuum [PDF]

open access: yesPhysical Review D, 2010
Motivated by the discovery of a plenitude of metastable vacua in a string landscape and the possibility of rapid tunneling between these vacua, we revisit the dynamics of a false vacuum bubble in a background de Sitter spacetime.

Vacuum Friction [PDF]

open access: yesJournal of Modern Optics, 2017
We know that in empty space there is no preferred state of rest. This is true both in special relativity but also in Newtonian mechanics with its associated Galilean relativity.

Vacuum Waves [PDF]

open access: yesPhysics Letters B, 2012
As an example of the unification of gravitation and particle physics, an exact solution of the five-dimensional field equations is studied which describes waves in the classical Einstein vacuum.

Levitodynamics: Levitation and control of microscopic objects in vacuum [PDF]

open access: yesScience, 2021
Description To have to hold The ability to couple the motion of levitated systems to internal degrees of freedom—in some cases down to their motional ground state—as well as to external forces and systems provides opportunities for fundamental science ...

Few-cycle vacuum squeezing in nanophotonics [PDF]

open access: yesScience, 2022
One of the most fundamental quantum states of light is the squeezed vacuum, in which noise in one of the quadratures is less than the standard quantum noise limit.

Breakdown of topological protection by cavity vacuum fields in the integer quantum Hall effect [PDF]

open access: yesScience, 2021
The prospect of controlling the electronic properties of materials via the vacuum fields of cavity electromagnetic resonators is emerging as one of the frontiers of condensed matter physics.

Sequential vacuum-evaporated perovskite solar cells with more than 24% efficiency

open access: yesScience Advances, 2022
Vacuum evaporation is promising for the high-throughput fabrication of perovskite solar cells (PSCs) because of its solvent-free characteristic, precise control of film thickness, and compatibility with large-scale production.

Cosmological constant—the weight of the vacuum [PDF]

open access: yes, 2002
Recent cosmological observations suggest the existence ofa positive cosmological constantwith the magnitude (G˝=c 3 ) ≈ 10 −123 . This review discusses several aspects ofthe cosmological constant both f rom the cosmological (Sections 1- 6) and .eld ...

Vacuum energy and θ-vacuum [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2004
The highly non-trivial structure of the $θ$--vacuum encodes many of the fundamental properties of gauge theories. In particular, the response of the vacuum to the $θ$--term perturbation is sensitive to the existence of confinement, chiral symmetry breaking, etc. We analyze the dependence of the vacuum energy density on theta around two special values, $

Three-pion contribution to hadronic vacuum polarization [PDF]

open access: yesJournal of High Energy Physics, 2019
We address the contribution of the 3π channel to hadronic vacuum polarization (HVP) using a dispersive representation of the e+e− → 3π amplitude. This channel gives the second-largest individual contribution to the total HVP integral in the anomalous ...
