Spacelike boundaries from the c=1 Matrix Model
Sumit R. Das, Joanna L. Karczmarek
We find classical solutions of two dimensional noncritical string theory which give rise to geometries with spacelike boundaries, similar to spacetimes with cosmological event hori…
Open-closed duality and Double Scaling
Sumit R. Das, Cesar Gomez
Nonperturbative terms in the free energy of Chern-Simons gauge theory play a key role in its duality to the closed topological string. We show that these terms are reproduced by pe…
Particle Production in Matrix Cosmology
Sumit R. Das, Joshua L. Davis, Finn Larsen +1
We consider cosmological particle production in 1+1 dimensional string theory. The process is described most efficiently in terms of anomalies, but we also discuss the explicit mod…
D branes in 2d String Theory and Classical limits
Sumit R. Das
In the matrix model formulation of two dimensional noncritical string theory, a D0 brane is identified with a single eigenvalue excitation. In terms of open string quantities (i.e…
