Under\r\na standard integrability assumption, the covariance depends solely on the\r\noverlap of the faces of the box. Beyond this assumption, a novel interpolating\r\ncovariance structure emerges. This enables us to identify a limiting Gaussian\r\n'coarse-grained' process, counting the number of points in large boxes as a\r\nfunction of the box position. Depending on the integrability assumption, this\r\nprocess may be continuous or discontinuous, e.g. in d=1 it is given by an\r\nincrement process of a fractional Brownian motion.","lang":"eng"}],"author":[{"orcid":"0000-0001-9624-2685","last_name":"Jalowy","full_name":"Jalowy, Jonas","first_name":"Jonas","id":"113768"},{"full_name":"Stange, Hanna","last_name":"Stange","first_name":"Hanna"}],"department":[{"_id":"94"}],"user_id":"113768","year":"2025","language":[{"iso":"eng"}],"_id":"60293","title":"Box-Covariances of Hyperuniform Point Processes","type":"preprint","citation":{"short":"J.
