Quantization of unstable linear scalar fields in static spacetimes
(2013-12-02)
We discuss the quantization of an unstable field through the construction of a one-particle Hilbert space. The system considered here is a neutral scalar field evolving over a globally hyperbolic static spacetime and subject ...
Extended stable equilibrium invaded by an unstable one
(2015)
Coexistence of states is an indispensable fea2
ture in the observation of domain walls, inter3
faces, shock waves or fronts in macroscopic sys4
tems. The propagation of these nonlinear waves
5 depends on the relative ...
Quantization of unstable linear scalar fields in static spacetimes
(Amer Physical Soc, 2013-12-02)
We discuss the quantization of an unstable field through the construction of a one-particle Hilbert space. The system considered here is a neutral scalar field evolving over a globally hyperbolic static spacetime and subject ...
UNSTABLE OBJECTS IN MOLECULAR CLOUD LDN133
(Springer, 2013)
The results of investigation of molecular cloud LDN133 and the unstable objects HHL59, HHL59A,
HHL59B and HHL59C connected with it are given. The IR nebula and IR star cluster are also connected
with LDN133. It is shown ...
Feedback stabilization of some unstable elliptic-parabolic systems
(2020)
This work presents feedback designs of exponentially
stabilizing boundary controllers for a one-dimensional system coupling elliptic and parabolic equations. The control acts on one Dirichlet boundary condition of the ...
A comparison of some simple methods used to detect unstable temperature responses in tree-ring chronologies
(Elsevier Gmbh, Urban & Fischer Verlag, 2018-04)
Temporal stability of the relationship between a potential proxy climate record and the climate record itself is the foundation of palaeoproxy reconstructions of past climate variability. Dendroclimatologists have spent ...
Socially unstable conditions experienced during development prime female Octodon degus to shape the phenotype of their own offspring
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2021-08)
Because residents and immigrants from group living species may experience fitness costs associated with permanent changes in group membership, we examined the hypothesis that females experiencing socially unstable or ...
