'Grey Galaxies' as an endpoint of the Kerr-AdS superradiant instability
Seok Kim, Suman Kundu, Eunwoo Lee +3
Kerr-AdS black holes for suffer from classical superradiant instabilities over a range of masses above extremality. We conjecture that these instabilities settle…
Single-Shot Readout of a Superconducting Qubit Using a Thermal Detector
András M. Gunyhó, Suman Kundu, Jian Ma +8
Measuring the state of qubits is one of the fundamental operations of a quantum computer. Currently, state-of-the-art high-fidelity single-shot readout of superconducting qubits re…
Measuring the properties of mode oscillations of a protoneutron star by third generation gravitational-wave detectors
Chaitanya Afle, Suman Kumar Kundu, Jenna Cammerino +4
Core-collapse supernovae are among the astrophysical sources of gravitational waves that could be detected by third-generation gravitational-wave detectors. Here, we analyze the gr…
Stars Crushed by Black Holes. III. Mild Compression of Radiative Stars by Supermassive Black Holes
Suman Kumar Kundu, Eric R. Coughlin, C. J. Nixon
A tidal disruption event (TDE) occurs when the gravitational field of a supermassive black hole (SMBH) destroys a star. For TDEs in which the star enters deep within the tidal radi…
Spherically Symmetric Accretion onto a Compact Object through a Standing Shock: The Effects of General Relativity in the Schwarzschild Geometry
Suman Kumar Kundu, Eric R. Coughlin
A core-collapse supernova is generated by the passage of a shockwave through the envelope of a massive star, where the shock wave is initially launched from the ``bounce'' of the n…
Does the Vacuum Gravitate on Microscopic Scales? Rydberg Atoms Indicate Probably Not
Suman Kumar Kundu, Arnab Pradhan, Carl Rosenzweig
The cosmological constant presents one of the most fascinating and confounding problems in physics. A straightforward, seemingly robust prediction of quantum mechanics and general…
A CFT interpretation of cosmological correlation functions in vacua in de-Sitter space
Sachin Jain, Nilay Kundu, Suman Kundu +2
de-Sitter(dS) space allows for a generalized class of vacua, known as vacua, described by some parameters. The Bunch-Davies (BD) vacua is a point in this parameter space. The c…
Dynamical stability of giant planets: the critical adiabatic index in the presence of a solid core
Suman Kumar Kundu, Eric R. Coughlin, Andrew N. Youdin +1
The dissociation and ionization of hydrogen, during the formation of giant planets via core accretion, reduces the effective adiabatic index of the gas and could trigger dynami…
Classification of all 3 particle S-matrices quadratic in photons or gravitons
Soumangsu Chakraborty, Subham Dutta Chowdhury, Tushar Gopalka +3
We explicitly construct every kinematically allowed three particle graviton-graviton- and photon-photon- S-matrix in every dimension and for every choice of the little group…
Optimizing the parton shower model in PYTHIA with pp collision data at = 13 TeV
S. K. Kundu, T. Sarkar, M. Maity
Production of quarks and gluons in hadron collisions tests Quantum Chromodynamics (QCD) over a wide range of energy. Models of QCD are implemented in event generators to simulate h…
