Detecting a long lived false vacuum with quantum quenches

Kavli Affiliate: Frank Wilczek | First 5 Authors: Gianluca Lagnese, Federica Maria Surace, Sid Morampudi, Frank Wilczek, | Summary: Distinguishing whether a system supports alternate low-energy (locally stable) states — stable (true vacuum) versus metastable (false vacuum) — by direct observation can be difficult when the lifetime of the state is very long but otherwise […]

Radio Pulsar B0950$+$08: Radiation in Magnetosphere and Sparks above Surface

Kavli Affiliate: Kejia Lee | First 5 Authors: Zhengli Wang, Jiguang Lu, Jinchen Jiang, Shunshun Cao, Kejia Lee | Summary: We observed the nearby 100$%$-duty-cycle radio pulsar B0950+08 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We obtained the polarization profile for its entire rotation, which enabled us to investigate its magnetospheric radiation geometry and […]

Critical properties of the quantum Ashkin-Teller chain with chiral perturbations

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bernhard Lüscher, Frédéric Mila, Natalia Chepiga, , | Summary: We investigate the nature of the phase transitions in the quantum Ashkin-Teller chain in the presence of chiral perturbations. We locate the Lifshitz line separating a region of direct chiral transitions from the region where the transition is […]

Unveiling Correlated Two-dimensional Topological Insulators through Fermionic Tensor Network States — Classification, Edge Theories and Variational Wavefunctions

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Chao Xu, Yixin Ma, Shenghan Jiang, , | Summary: The study of topological band insulators has revealed fascinating phases characterized by band topology indices and anomalous boundary modes protected by global symmetries. In strongly correlated systems, where the traditional notion of electronic bands becomes obsolete, it has […]

Population synthesis of Be X-ray binaries: metallicity dependence of total X-ray outputs

Kavli Affiliate: George Efstathiou | First 5 Authors: Boyuan Liu, Nina S. Sartorio, Robert G. Izzard, Anastasia Fialkov, | Summary: X-ray binaries (XRBs) are thought to regulate cosmic thermal and ionization histories during the Epoch of Reionization and Cosmic Dawn ($zsim 5-30$).Theoretical predictions of the X-ray emission from XRBs are important for modelling such early […]
