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…
Large-charge ADHM-BMN index matching
Sarthak Duary, Kangning Liu
We compare the superconformal index of three-dimensional ADHM theory in fixed monopole sectors with the index of the BMN matrix model around fuzzy-sphere vacua. The monopole charge…
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…
Liénard--Wiechert fields in AdS and flat-space antipodal matching from geodesic-centered Coulombic data
Sarthak Duary
We present a geometric derivation of Liénard--Wiechert fields in flat-space and AdS, emphasizing the origin of antipodal matching. In flat-space, the field of a uniformly moving ch…
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…
Finite- BMN index across all vacuum sectors
Chi-Ming Chang, Sarthak Duary, Kangning Liu
We compute the finite- Witten index of BMN matrix quantum mechanics after summing over all partition-labeled supersymmetric vacuum sectors. Starting from the unitary-matrix inte…
Mass-Flow Invariance of -Cohomology in BMN Matrix Quantum Mechanics
Chi-Ming Chang, Zhengyuan Du, Sarthak Duary +2
We study the dependence of the dynamical supercharges of BMN matrix quantum mechanics on the mass parameter . Taking the -derivative at fixed canonical matrix variables, we s…
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…
