Unstable D-branes and String Cosmology
Chanju Kim, Hang Bae Kim, Yoonbai Kim +2
Cosmological implication of rolling tachyons is reported in the context of effective field theory. With a brief review of rolling tachyons in both flat and curved spacetimes, we st…

Cosmology of Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study dynamics of rolling tachyon and Abelian gauge field on unstable D-branes, of which effective action is given by Born-Infeld type nonlocal action. Possible cosmological evo…

On mass dependences of the one-loop effective action in simple backgrounds
O-Kab Kwon, Choonkyu Lee, Hyunsoo Min
If background fields are soft on the scale set by mass of the particle involved, a reliable approximation to the field-theoretic one-loop effective action is obtained by a systemat…
