Journal ArticleDOI
Macroscopic polarization in crystalline dielectrics : the geometric phase approach
TL;DR: In this paper, King-Smith and Vanderbilt developed a complete theory in which the polarization difference between any two crystal states in a null electric field takes the form of a geometric quantum phase.
Journal ArticleDOI
Quantum-Mechanical Position Operator in Extended Systems
Raffaele Resta,Raffaele Resta +1 more
TL;DR: In this article, the position expectation value is defined by means of a simple many-body operator acting on the wave function of the extended system, and the relationships of the present findings to the Berry-phase theory of polarization are discussed.
Journal ArticleDOI
Band offsets in lattice-matched heterojunctions: A model and first-principles calculations for GaAs/AlAs.
TL;DR: In this paper, a new model for band offsets in lattice-matched heterojunctions is presented along with a novel definition of the interface dipole which avoids any reference to an ideal interface.
Journal ArticleDOI
Ab initio calculation of the macroscopic dielectric constant in silicon.
Stefano Baroni,Raffaele Resta +1 more
TL;DR: The present calculation gives for the first time the ``exact'' value of the macroscopic dielectric constant at the LDA level.
Journal ArticleDOI
Theory of the electric polarization in crystals
TL;DR: In this paper, the state-of-the-art for induced and spontaneous polarization in real materials is presented, both for spontaneous and induced polarization, and for the latter case, a novel approach is proposed.
