Time-dependent 2D spacetimes from matrices

Research output: Contribution to journalShort surveypeer-review

3 Scopus citations


Solutions of matrix quantum mechanics have been shown to describe time dependent backgrounds in the holographically dual two-dimensional closed string theory. We review some recent work dealing with nontrivial spacetimes which arise in this fashion and discuss aspects of physical phenomena in them. These include spacetimes with spacelike boundaries.
