Can topological defects be formed during preheating ?
We study the dynamics of a scalar field Φ with potential g(|Φ|− η)/2 (g: self-coupling constant, η: symmetry breaking scale) after inflation and make clear whether topological defects can ever be formed during preheating. In particular, we pay attention to the GUT defects (η ∼ 10GeV − 10GeV), and consider three types of fluctuations. The first one is produced due to parametric resonance, the se...
متن کاملEvolution of topological defects during inflation.
Topological defects can be formed during inflation by phase transitions as well as by quantum nucleation. We study the effect of the expansion of the Universe on the internal structure of the defects. We look for stationary solutions to the field equations, i.e. solutions that depend only on the proper distance from the defect core. In the case of very thin defects, whose core dimensions are mu...
متن کاملCan topological defects mimic the BICEP2 B-mode signal?
We show that the B-mode polarization signal detected at low multipoles by BICEP2 cannot be entirely due to topological defects. This would be incompatible with the high-multipole B-mode polarization data and also with existing temperature anisotropy data. Adding cosmic strings to a model with tensors, we find that B modes on their own provide a comparable limit on the defects to that already co...
متن کاملHow can Alzheimer's Patients be Helped?
پرستاری از بیمار مبتلا به بیماری آلزایمر چندان ساده نیست. حتی اگر از این امر که اختلال رفتاری فرد نشانه ای از بیماری اوست، آگاه باشید، اکثر مواقع نمی دانید که چگونه باید با او رفتار کنید. در این مقاله روشهای مناسبی ارائه گردیده تا خانواده بیمار بتواند با ۱۰ اختلال رفتاری شایع در بیماران مبتلا بدون احساس ناامیدی و خشم سازگاری یابند.
متن کاملCan Anal Sphincter Defects Be Identified by Palpation?
OBJECTIVES The aim of this study was to correlate clinical findings of anal sphincter defects and function with a sonographic diagnosis of significant sphincter defects. METHODS This is an observational cross-sectional study on women seen 6 to 10 weeks after primary repair of obstetric anal sphincter injuries (OASIs). All patients underwent a standardized interview including the St Mark incon...
