with string theorists coming up with the “string version” of things others understand in other ways. This, for the most part, doesn’t happen. Without knowing whether string theory is true, there isn’t much benefit in just translating other things to string theory terms, and people for ...
For the rest, the question of whether string theory describes the real world takes a back seat. They’re people who “have” string theory in the sense that they’re experts, and they use the theory primarily as a mathematical laboratory to learn broader things about how physics works. If ...
A few of these people can get more combative, or make unwarranted assumptions based on dedication to string theory in particular: for example, you’ll see the occasional argument that because something is difficult in string theory it must be impossible in any theory of quantum gravity. You ...
1. By coloring the D-brane worldvolume, we are able to show how, in the string theory, the giant graviton factorizes at its maximal size into two dibaryons - topologically stable D-branes wrapping non-contractible cycles in theT1,1....
that graviton edge modes are hence thed– 2 large diffeomorphisms which act internally within the Rindler horizon. Along the way, we address several known issues regarding graviton entanglement. We furthermore sketch how our results may be used to study edge modes in closed bosonic string theory....
关键词: AdS-CFT Correspondence D-branes Black Holes in String Theory 被引量: 30 摘要: We explore 1/16-BPS objects of type IIB string theory in AdS× S. First, we consider supersymmetric AdSblack holes, which should be 1/16-BPS and have a characteristic that not all physical charges ...
We describe closed string modes by open Wilson lines in noncommutative (NC) gauge theories on compact fuzzy G/H in IIB matrix model. In this construction the world sheet cut-off is related to the spacetime cut-off since the string bit of the symmetric traced Wilson line carries the minimum...
of background fields in string theory side. This fluctuation will lead to the fluctuation of the D3-brane solution we obtained before. Figure from [a talk by Ahn] Three point functions • The induced variation of the on-shell D-brane ...
String theory provides a beautiful interpretation of the double copy as relating closed string amplitudes to open string amplitudes; where gravitons, as massless vibrations of closed strings, arise from joining the endpoints of a pair of open strings. In fact, the tree-level BCJ structure has ...
We study the worldsheet reflection matrix of a string attached to a D‐brane inAdS5×S5.The D‐brane corresponds to a maximal giant graviton that wraps anS3insideS5.In the gauge theory, the open string is described by a spin chain with boundaries. We focus on open strings with a largeSO...
