Cosmic string review
WebThe standard model of a cosmic string is a geometrical structure with an angle deficit, which thus is in tension and hence has positive mass. In 1995, Visser et al. proposed that … WebG is Newton’s constant, μ is the cosmic-string tension (i.e., energy per unit length), k labels the harmonic modes of cosmic-string loops, and P k ¼ Γ=kq=ζðqÞ is the averaged GW power spectrum. We assume that P k is dominated by cusps propagating along cosmic-string loops (q ¼ 4=3). P k is normalized such that the total emitted power ...

WebThe behavior of a quantum test particle satisfying the Klein-Gordon equation in a certain class of 4 dimensional stationary space-times is examined. In a space-time of a spinning cosmic string, the wave function of a particle in a box is shown to acquire a geometric phase when the box is transported around a closed path surrounding the string. WebApr 24, 2024 · Dubbed cosmic strings, mathematical models see them as invisible threads of pure energy, thinner than an atom but light-years long. The huge amount of energy they contain also makes them...
