    • Classification of fragile topology enabled by matrix homotopy 

      Lee, Ki Young; Wong, Stephan; Vaidya, Sachin; Loring, Terry A.; Cerjan, Alexander (American Physical Society (APS), 2025-09-10)
      Flat bands in twisted materials have attracted considerable attention due to the emergence of correlated phases that can be associated with the non-Wannier-representable nature of its single-particle states. Specifically, ...
    • Universality of the perturbative definition of the Flory-Huggins parameter 

      Petrov, Artem; Hernández-Mendoza, Guillermo A; Alexander-Katz, Alfredo (American Physical Society (APS), 2026-03-09)
      The effective Flory-Huggins parameter χe is one of the most important characteristics of any multicomponent polymer system. This parameter characterizes the free energy of interaction between monomers of different types ...
    • Asymmetry of the Distribution of Vertical Velocities of the Extratropical Atmosphere in Theory, Models, and Reanalysis 

      Kohl, Matthieu; O’Gorman, Paul A (American Meteorological Society, 2024-03-01)
      The vertical velocity distribution in the atmosphere is asymmetric with stronger upward than downward motion. This asymmetry is important for the distribution of precipitation and its extremes and for an effective static ...
