Pure D-brane Black Holes: BPS Counting and non-BPS Vacua
Abhishek Chowdhury, Sourav Maji
In this paper, we present a unified computational framework to analyze the microscopic vacuum structure of 4-charge extremal black holes in Type IIA string theory, applying techniq…
Warp Drives and Martel-Poisson charts
Abhishek Chowdhury
We extend the construction of Alcubierre-Natário class of warp drives to an infinite class of spacetimes with similar properties. This is achieved by utilising the Martel-Poisson…
Information Scrambling with Higher-Form Fields
Karunava Sil, Sourav Maji, Stavros Christodoulou +1
The late time behaviour of OTOCs involving generic non-conserved local operators show exponential decay in chaotic many body systems. However, it has been recently observed that fo…
Counting Black Holes as Algebraic Varieties
Abhishek Chowdhury, Sourav Maji
We calculate the helicity trace index for pure D-brane black holes using various techniques of computational algebraic geometry and find perfect agreemen…
