Contribution
It establishes a link between D0-branes in Gepner models and extremal black holes, providing a new perspective on their dynamics and charge properties.
Findings
D-brane boundary states correspond to BPS dyonic objects
A correspondence between D0-branes and extremal black holes is demonstrated
Couplings to closed string fields elucidate the black hole analogy
Abstract
In this paper D-brane boundary states constructed in Gepner models are used to analyze some aspects of the dynamics of D0-branes in Calabi-Yau compactifications of type II theories to four dimensions. It is shown that the boundary states correspond to BPS objects carrying dyonic charges. By analyzing the couplings to closed string fields a correspondence between the D0-branes and extremal charged black holes in N=2 supergravity is found.
