2D Theoretically Twistable Material Database
Yi Jiang, Urko Petralanda, Grigorii Skorupskii +30
The study of twisted two-dimensional (2D) materials, where twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly c…
Two-dimensional Topological Quantum Chemistry and Catalog of Topological Materials
Urko Petralanda, Yi Jiang, Hanqi Pi +4
Two-dimensional topological materials host symmetry-protected, disorder-robust edge states cen- tral to quantum technologies. Yet, they remain scarce compared with their three-dime…
Universal Moiré-Model-Building Method without Fitting: Application to Twisted MoTe and WSe
Yan Zhang, Hanqi Pi, Jiaxuan Liu +8
We develop a comprehensive method to construct analytical continuum models for moiré systems directly from first-principle calculations without any parameter fitting. The core idea…
StarDICE III: Characterization of the photometric instrument with a Collimated Beam Projector
Thierry Souverin, Jérémy Neveu, Marc Betoule +18
The measurement of type Ia supernovae magnitudes provides cosmological distances, which can be used to constrain dark energy parameters. Large photometric surveys require a substan…
Regularizing 3D conformal field theories via anyons on the fuzzy sphere
Cristian Voinea, Ruihua Fan, Nicolas Regnault +1
Recently introduced ''fuzzy sphere'' method has enabled accurate numerical regularizations of certain three-dimensional (3D) conformal field theories (CFTs). The regularization is…
How the StarDICE photometric calibration of standard stars can improve cosmological constraints?
T. Souverin, J. Neveu, M. Betoule +16
The number of type Ia supernova (SNe Ia) observations will grow significantly within the next decade, mainly thanks to the Legacy Survey of Space and Time (LSST) undertaken by the…
