Thomas Creutzig, Thomas Quella, Volker Schomerus
TL;DR
This paper introduces a new boundary condition for the c=-2 ghost system, constructing its boundary state and demonstrating it as the first local logarithmic boundary sector with diagonalizable Virasoro zero modes.
Contribution
It presents the first example of a local logarithmic boundary sector in a bulk theory with diagonalizable Virasoro zero modes for the c=-2 ghost system.
Findings
Constructed the boundary state for the new boundary condition
Demonstrated the boundary sector is logarithmic and local
First example with diagonalizable Virasoro zero modes in such a context
Abstract
We investigate a novel boundary condition for the bc system with central charge c=-2. Its boundary state is constructed and tested in detail. It appears to give rise to the first example of a local logarithmic boundary sector within a bulk theory whose Virasoro zero modes are diagonalizable.
