Taming the Tachyon in Cubic String Field Theory
Erasmo Coletti, Ilya Sigalov, Washington Taylor
We give evidence based on level-truncation computations that the rolling tachyon in cubic open string field theory (CSFT) has a well-defined but wildly oscillatory time-dependent s…
Exact potential and scattering amplitudes from the tachyon non-linear -function
E. Coletti, V. Forini, G. Grignani +2
We compute, on the disk, the non-linear tachyon -function, , of the open bosonic string theory. is determined both in an expansion to the third power of the field and…
Abelian and nonabelian vector field effective actions from string field theory
Erasmo Coletti, Ilya Sigalov, Washington Taylor
The leading terms in the tree-level effective action for the massless fields of the bosonic open string are calculated by integrating out all massive fields in Witten's cubic strin…
Lattice Gauge Theories and the Heisenberg Antiferromagnetic Chain
F. Berruto, E. Coletti, G. Grignani +1
We study the strongly coupled 2-flavor lattice Schwinger model and the SU(2)-color QCD_2. The strong coupling limit, even with its inherent nonuniversality, makes accurate predicti…
