Reaction of deuteron with a heavy nucleus at low energies

Pankaj Jain, Harishyam Kumar, K. Ramkumar

We extend the recently proposed mechanism for inducing low energy nuclear reactions (LENR) to compute the reaction rate of deuteron with a heavy nucleus. The process gets dominant…

Low Energy Nuclear Reactions Through Weak Interactions

K. Ramkumar, Harishyam Kumar, Pankaj Jain

We consider the possibility that low-energy nuclear reactions (LENR) arise due to the conversion of proton to neutron through weak interactions. The resulting neutron forms a short…

Renormalization of Scalar and Fermion Interacting Field Theory for Arbitrary Loop: Heat-Kernel Approach

Upalaparna Banerjee, Joydeep Chakrabortty, Kaanapuli Ramkumar

We outline a proposal, based on the Heat-Kernel method, to compute 1PI effective action up to any loop order for quantum field theory with scalar and fermion fields. We algebraical…

One-loop Effective Action up to any Mass-dimension for Non-degenerate Scalars and Fermions including Light-Heavy Mixing

Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1

We propose a Heat-Kernel-based method to compute one-loop effective action up to any mass-dimension with arbitrary numbers of non-degenerate scalars and fermions. We demonstrate ou…

Low energy nuclear reactions in a crystal lattice

Harishyam Kumar, Pankaj Jain, K. Ramkumar

We extend the recently proposed mechanism for inducing low energy nuclear reactions (LENRs) to a crystal lattice. The process gets a dominant contribution at second order in quantu…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Fermion(s)

Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar

We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Scalar(s)

Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1

We present the complete one-loop effective action up to dimension eight after integrating out degenerate scalars using the Heat-Kernel method. The result is provided without assumi…

A Toy Model for Low Energy Nuclear Fusion

Kaanapuli Ramkumar, Harishyam Kumar, Pankaj Jain

We study the fusion of a proton with a nucleus with the emission of two photons at low incident energy of the order of eV or smaller. We use a step model for the repulsive potentia…

Uncertainties in the Transport Properties of Helium Gas at Cryogenic Temperatures Determined Using Molecular Dynamics Simulation

Kaanapuli Ramkumar, Swati Swagatika Mishra, Sudeep Bhattacharjee

In this study, the transport properties, such as diffusivity, viscosity, and thermal conductivity, of 4He at the gaseous phase are computed for state points in the temperature rang…
