Boundary States for AdS_2 Branes in AdS_3
Peter Lee, Hirosi Ooguri, Jongwon Park
We construct boundary states for the AdS_2 D-branes in AdS_3. We show that, in the semi-classical limit, the boundary states correctly reproduce geometric configurations of these b…
Permeable conformal walls and holography
C. Bachas, J. de Boer, R. Dijkgraaf +1
We study conformal field theories in two dimensions separated by domain walls, which preserve at least one Virasoro algebra. We develop tools to study such domain walls, extending…
Strings in AdS_3 and the SL(2,R) WZW Model. Part 3: Correlation Functions
Juan Maldacena, Hirosi Ooguri
We consider correlation functions for string theory on AdS_3. We analyze their singularities and we provide a physical interpretation for them. We explain which worldsheet correlat…
Holography and Defect Conformal Field Theories
Oliver DeWolfe, Daniel Z. Freedman, Hirosi Ooguri
We develop both the gravity and field theory sides of the Karch-Randall conjecture that the near-horizon description of a certain D5-D3 brane configuration in string theory, realiz…
Open Strings on AdS_2 Branes
Peter Lee, Hirosi Ooguri, Jongwon Park +1
We study the spectrum of open strings on AdS_2 branes in AdS_3 in an NS-NS background, using the SL(2,R) WZW model. When the brane carries no fundamental string charge, the open st…
Seiberg-Witten Transforms of Noncommutative Solitons
Koji Hashimoto, Hirosi Ooguri
We evaluate the Seiberg-Witten map for solitons and instantons in noncommutative gauge theories in various dimensions. We show that solitons constructed using the projection operat…
