Carroll-Weyl gauged null strings in AdS
Sarthak Duary, Sourav Maji
We study the Carroll-Weyl gauged null string in the Poincaré patch of and its BRST quantization. In Poincaré coordinates , the radial conformal Killin…
Neumann Schrödinger Estimates in Cylindrical Domains
Len Meas
We establish sharp local-in-time dispersive estimates and global Strichartz estimates for the semiclassical Schrödinger equation in a three-dimensional cylindrical domain $Ω\subset…
Tropical Open Strings in a Kalb-Ramond Background
Sarthak Duary, Vi Hong, Sourav Maji
We study tropical open strings arising from the analytically continued action of tropological sigma models in the presence of a constant Kalb-Ramond background. We show that the ba…
BRST quantization of Carroll-Weyl gauged null strings
Sarthak Duary, Sourav Maji
We study the BRST quantization of the null string after completing its local gauge symmetry by Carroll-Weyl transformations. The resulting worldsheet theory possesses three first-c…
Path integral quantization of null bosonic strings with Carroll-Weyl ghosts
Sarthak Duary, Sourav Maji
We revisit the path integral quantization of the null bosonic string from the viewpoint that all local gauge symmetries of the Carrollian worldsheet must be gauge fixed before the…
Covariant phase space approach to noncommutativity in tensile and tensionless open strings
Pratik K. Das, Sarthak Duary, Sourav Maji
We study noncommutativity in open strings using the covariant phase space formalism. For tensile open strings in a constant Kalb-Ramond background, we show that the (pre)-symplecti…
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…
From closed to open strings: the tensionless route in Kalb-Ramond background and noncommutativity
Sarthak Duary, Sourav Maji
We study tensionless bosonic strings propagating in the presence of a constant Kalb--Ramond background and show how closed strings undergo a transition into open strings. Working i…
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…
Spectral representation in Klein space: simplifying celestial leaf amplitudes
Sarthak Duary, Sourav Maji
In this paper, we explore the spectral representation in Klein space, which is the split signature flat spacetime. The Klein space can be foliated into Lorentzian $\mathrm{…
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…
High Speed Elephant Flow Detection Under Partial Information
Jordi Ros-Giralt, Alan Commike, Sourav Maji +1
In this paper we introduce a new framework to detect elephant flows at very high speed rates and under uncertainty. The framework provides exact mathematical formulas to compute th…
