D-brane decay in two-dimensional string theory
TL;DR: In this article, the authors considered unstable D0-branes of two-dimensional string theory, described by the boundary state of Zamolodchikov and Verlinde [36] multiplied by the Neumann boundary state for the time coordinate t. This coherent state agrees with the exponential of the closed string one-point function on a disk with Sen's marginal boundary interaction for t which describes D-brane decay.

D-brane Decay in Two-Dimensional String Theory
TL;DR: In this paper, the authors considered unstable D0-branes of two-dimensional string theory, described by the boundary state of Zamolodchikov and Verlinde [hep-th/0304224] multiplied by the Neumann boundary state for the time coordinate $t.
Journal ArticleDOI
Rényi entropies for free field theories
TL;DR: In this paper, the Renyi entropies of free massless scalars and fermions in d = 2 were calculated using zeta-function regularization, and the results showed agreement between the calculations on the branched coverings of S petertodd 3 and on S petertodd 1 × $ {\mathbb{H}^2} $cffff, respectively.

Proton decay in intersecting D-brane models
Igor R. Klebanov,Edward Witten +1 more
TL;DR: In this paper, the authors analyzed proton decay via dimension-six operators in certain GUT-like models derived from Type IIA orientifolds with D6-branes and found that the amplitude is parametrically enhanced by a factor of α GUT −1/3 relative to the corresponding result in four-dimensional GUTs.
