Author(s): S. Acharya et al. (ALICE Collaboration)This Letter presents the measurement of near-side associated per-trigger yields, denoted ridge yields, from the analysis of angular correlations of charged hadrons in proton-proton collisions at s=13 TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity dif…...
Author(s): Daniel G. Figueroa, Mauro Pieroni, Angelo Ricciardone, and Peera SimakachornWe discuss the interpretation of the detected signal by pulsar timing array (PTA) observations as a gravitational wave background of cosmological origin. We combine NANOGrav 15-years and EPTA-DR2new datasets and confront them against backgrounds from supermassive...
Author(s): Tevž Lotrič and Steven H. SimonThe ν=12+12 quantum Hall bilayer has been previsously modeled using Chern-Simons-RPA-Eliashberg (CSRPAE) theory to describe pairing between the two layers. However, these approaches are troubled by a number of divergences and ambiguities. By using a “modified” RPA approximation to account for mass r… [Phys....
Author(s): Yu-Hsueh Chen and Tarun GroverWe study states with intrinsic topological order subjected to local decoherence from the perspective of separability, i.e., whether a decohered mixed state can be expressed as an ensemble of short-range entangled pure states. We focus on toric codes and the X-cube fracton state and provide evidence … [Phys. Rev....

Mihaylov, Samanta Saha, Andrius Tamosiunas, Quinn Taylor, and Valeri Vardanyan (COMPACT Collaboration)Most models for the overall shape and geometry of the Universe—including...
Author(s): Ri He, Haowei Xu, Peijun Yang, Kai Chang, Hua Wang, and Zhicheng ZhongFerroelastic twin walls in nonpolar materials can give rise to a spontaneous polarization due to symmetry breaking. Nevertheless, the bistable polarity of twin walls and its reversal have not yet been demonstrated. Here, we report that the polarity of SrTiO3 twin walls...
