WebContribute to QEF/qeschema development by creating an account on GitHub. WebA simple bug: in the final printing of a polarization computation using the Berry phase (lberry=.true.), when converting from e/Bohr^2 to C/m^2, the code uses a wrong electron unit charge (1.60097E-19 Coulombs). The exact value is 1.602176634E-19 Coulombs. This result in a 0.09% underestimate of the SI polarization value. grand isle louisiana pictures https://otterfreak.com
