The local spectrum of the Dirac operator for the universal cover of SL_2(R) [PDF]
, 2016 Using representation theory, we compute the spectrum of the Dirac operator on the universal covering group of SL2(R)SL2(R), exhibiting it as the generator of KK1(C,A)KK1(C,A), where AA is the reduced C?C?-algebra of the group.

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System
Advanced Science, EarlyView.An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Periódicos Brasil. Pesquisa CientíficaEste artigo investiga, sob uma perspectiva rigorosamente analítica e funcional, as relações estruturais entre a função zeta de Riemann, a função delta de Dirac e a transformada de Mellin, enfatizando o papel das distribuições na compreensão espectral dos números inteiros.

CLRe: A Synergistic Dual‐Engine Framework for One‐Step Retrosynthesis Prediction
Advanced Science, EarlyView.CLRe uses a contrastive difficulty score to order pretrained seq2seq fine‐tuning for retrosynthesis. Reaction embeddings define the ranking score, and a cumulative easy‐to‐hard schedule expands from the easiest subset to the full training set while earlier examples remain active.

Transparent Topological Meta‐Diplexer via Tightly Confined Valley Surface States
Advanced Science, EarlyView.An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...
