Quantum fluctuations in planar domain-wall space-times: A possible origin of primordial preferred direction
Quantum fluctuations planar domain-wall space-times possible origin primordial preferred direction
2011/10/18
We study the gravitational effects of a planar domain wall on quantum fluctuations of a massless scalar field during inflation. By obtaining an exact solution of the scalar field equation in de Sitter...
Possible Origin of the Anomalous Far-infrared Absorption by Small Metal Particles
Origin of the Anomalous Far-infrared Absorption Small Metal Particles
2010/11/18
We have carried out far-infrared (far-IR) transmission measurements on the ligand stabilized
Au55 particles dispersed in CsI at volume fraction f = 0.002. We have found that while the
absorption coe...
