Resonance structures in kink-antikink scattering in a quantum vacuum
Mainak Mukhopadhyay, Tanmay Vachaspati
We investigate kink-antikink scattering in the model in the presence of an additional scalar field, , that is in its quantum vacuum and interacts with via a …
Neutrinos from the Brightest Gamma-Ray Burst?
Kohta Murase, Mainak Mukhopadhyay, Ali Kheirandish +2
We discuss implications that can be obtained by searches for neutrinos from the brightest gamma-ray burst, GRB 221009A. We derive constraints on GRB model parameters such as the co…
Searching for supernova neutrinos with GW memory triggers
Mainak Mukhopadhyay
Anisotropic neutrino emission from a core-collapse supernova (CCSN) causes a permanent change in the local space-time metric, called the gravitational wave (GW) memory. Long consid…
Memory-triggered supernova neutrino detection
Mainak Mukhopadhyay, Zidu Lin, Cecilia Lunardini
We demonstrate that observations of the gravitational memory from core collapse supernovae at future Deci-Hz interferometers enable time-triggered searches of supernova neutrinos a…
Kink-antikink scattering in a quantum vacuum
Mainak Mukhopadhyay, Evangelos I. Sfakianakis, Tanmay Vachaspati +1
We study kink-antikink scattering in the sine-Gordon model in the presence of interactions with an additional scalar field, , that is in its quantum vacuum. In contrast to the c…
The neutrino gravitational memory from a core collapse supernova: phenomenology and physics potential
Mainak Mukhopadhyay, Carlos Cardona, Cecilia Lunardini
General Relativity predicts that the passage of matter or radiation from an asymmetrically-emitting source should cause a permanent change in the local space-time metric. This phen…
Quantum Formation of Topological Defects
Mainak Mukhopadhyay, Tanmay Vachaspati, George Zahariade
We consider quantum phase transitions with global symmetry breakings that result in the formation of topological defects. We evaluate the number densities of kinks, vortices, and m…
Emergence of classical structures from the quantum vacuum
Mainak Mukhopadhyay, Tanmay Vachaspati, George Zahariade
After a quantum phase transition the quantum vacuum can break up to form classical topological defects. We examine this process for scalar field models with symmetry for diff…
Presupernova neutrinos: directional sensitivity and prospects for progenitor identification
Mainak Mukhopadhyay, Cecilia Lunardini, F. X. Timmes +1
We explore the potential of current and future liquid scintillator neutrino detectors of O (10) kt mass to localize a pre-supernova neutrino signal in the sky. In the hours precedi…
Rolling with quantum fields
Mainak Mukhopadhyay, Tanmay Vachaspati
We study the dynamics of a classical scalar field that rolls down a linear potential as it interacts bi-quadratically with a quantum field. We explicitly solve the dynamical proble…
