| 1 | Machine learning of superconducting critical temperature from Eliashberg theory显示文摘The Eliashberg theory of superconductivity accounts for the fundamental physics of conventional superconductors,including the retardation of the interaction and the Coulomb pseudopotential,to predict the critical temperature T_(c).McMillan,Allen,and Dynes derived approximate closed-form expressions for the critical temperature within this theory,which depends on the electron–phonon spectral functionα^(2)F(ω).Here we show that modern machine-learning techniques can substantially improve these formulae,accounting for more general shapes of theα^(2)F function.Using symbolic regression and the SISSO framework,together with a database of artificially generatedα^(2)F functions and numerical solutions of the Eliashberg equations,we derive a formula for T_(c)that performs as well as Allen–Dynes for low-T_(c)superconductors and substantially better for higher-T_(c)ones.This corrects the systematic underestimation of Tc while reproducing the physical constraints originally outlined by Allen and Dynes.This equation should replace the Allen–Dynes formula for the prediction of higher-temperature superconductors. | S.R.Xie Y.Quan A.C.Hire B.Deng J.M.DeStefano I.Salinas U.S.Shah L.Fanfarillo J.Lim J.Kim G.R.Stewart J.J.Hamlin P.J.Hirschfeld R.G.Hennig | 2022 | npj Computational Materials2022，，1： | 2 |

| 6 | 提心吊胆的华尔街显示文摘 The war in Iraq, terrorism, rising oil prices-and now the threat of higher interest rates-are all preying on the market.
There comes a point in virtually every bull market when the risk takers step aside, giving way to the worrywarts1on Wall Street. That's where the market finds itself today,at a crossroads that could lead either to the second year of this bull market or down a dead-end street.
