Although the dynamics of this model is very involved, asymptotically, as the singularity is approached, it can be well approximated as a succession of Bianchi I periods connected by quick bounces against potential walls. Moreover, in such limit, matter fields (excluding stiff matter) are known to be subdominant with respect to the anisotropies. Therefore, by performing an expansion around small volumes, and assuming that the matter contribution in this regime can be described as a barotropic perfect fluid with a linear equation of state, we obtain an approximate analytic solution of the dynamics. Then, we explicitly compute the form of the transition (Kasner) map that relates the pre- and postbounce Bianchi I periods including the leading matter effects. As an important conclusion, we observe that generically the presence of matter leads to a postbounce velocity with a lower deflection angle than in the vacuum case, and thus effectively increases the convex curvature of the potential walls. This effect may have important consequences in the chaotic nature of general relativity near spacelike singularities.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"34 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a model that quantifies the relationship between temperature noise and the optical path variation is proposed to analyze the thermo-optic noise of optical coating. There are two types of temperature-dependent noise—the traditional equilibrium thermal noise and the position noise introduced by the overall temperature fluctuation in the telescope load—that need to be considered for space gravitational wave detection satellites. In the current off-axis quad-mirror design, the incident angle of light from each mirror is very different, and the maximum incident angle reaches nearly 45°. The optical path noise of all-dielectric reflective coating will be more significant under the large incident angle. Metal reflective coating can effectively suppress the optical path noise caused by low-frequency temperature fluctuation, making them a viable alternative for space gravitational wave detectors. This paper provides a valuable reference for the selection of reflective coatings in space-based gravitational wave telescopes from the perspective of coating noise.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"16 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider quasicircular and eccentric binaries, dynamical captures and radial infalls, with orbital dynamics driven by an highly accurate analytical radiation reaction. After reviewing the description of the late-time behavior as an integral over the whole inspiral history, we derive an analytical expression that reproduces the slow relaxation (“tail”) observed in our numerical evolutions, obtained with a hyperboloidal compactified grid, for a given noncircular particle trajectory. We find this signal to be a superposition of an infinite number of power-laws, the slowest decaying term being Price’s law. Next, we use our model to explain the several orders-of-magnitude enhancement of tail terms for binaries in noncircular orbits, shedding light on recent unexpected results obtained in numerical evolutions. In particular, we show the dominant terms controlling the enhancement to be activated when the particle is far from the black hole, with small tangential and radial velocities soon before the plunge. As we corroborate with semianalytical calculations, this implies that for large eccentricities the tail amplitude can be correctly extracted even when starting to evolve only from the last apastron before merger. We discuss the implications of these findings on the extraction of late-time tail terms in nonlinear evolutions and possible observational consequences. We also briefly comment on the scattering scenario and on the connection with the soft graviton theorem.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"62 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
