Bulk reconstruction using timelike entanglement in (A)dS
Avijit Das, Shivrat Sachdeva, Debajyoti Sarkar
It is well-known that the entanglement entropies for spacelike subregions, and the associated modular Hamiltonians play a crucial role in the bulk reconstruction program within Ant…
String Thermodynamics In and Out of Equilibrium: Boltzmann Equations and Random Walks
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +3
We revisit the study of string theory close to the Hagedorn temperature with the aim towards cosmological applications. We consider interactions of open and closed strings in a gas…
Coherent States in M-Theory: A Brane Scan using the Taub-NUT
Joydeep Chakravarty, Keshav Dasgupta, Diksha Jain +3
The Taub-NUT geometry corresponds to the Kaluza-Klein monopole solution of M-theory and on dimension reduction along the Taub-NUT circle direction it becomes the D6 brane of type I…
Loop Amplitudes in the Coulomb Branch of Super-Yang-Mills Theory
Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +2
We study four point planar loop amplitudes at an arbitrary point in the Coulomb branch of super-Yang-Mills theory. We study two particle unitary cuts up to four loo…
Effective Gravitational Couplings of Kaluza-Klein Gauge Theories
Sujay K. Ashok, Renjan Rajan John, T. J. Layon +2
We study the effective gravitational couplings of four-dimensional Kaluza-Klein compactified gauge theories with eight supercharges. The class of theories we consider are the pure…
