Random phase approximation with exchange for an accurate description of crystalline polymorphism
Maria Hellgren, Lucas Baguet
We determine the correlation energy of BN, SiO and ice polymorphs employing a recently developed RPAx (random phase approximation with exchange) approach. The RPAx provides lar…

Electronic structure of TiSe from a quasi-self-consistent GW approach
Maria Hellgren, Lucas Baguet, Matteo Calandra +2
In a previous work it was shown that the inclusion of exact exchange is essential for a first principles description of both the electronic- and the vibrational properties of TiSe$…
