Hamiltonian formulation of the -dimensional theory in a momentum-space Daubechies wavelet basis
Mrinmoy Basak, Debsubhra Chakraborty, Nilmani Mathur +1
We apply the wavelet formalism of quantum field theory to investigate nonperturbative dynamics within the Hamiltonian framework. In particular, we employ Daubechies wavelets in mom…
Hamiltonian Flow Equations in Daubechies Wavelet Basis
Mrinmoy Basak, Raghunath Ratabole
We study the low energy dynamics of a system of two coupled real scalar fields in 1+1 dimensions using the flow equation approach of Similarity Renormalization Group (SRG) in a wav…
Renormalization in Wavelet basis
Mrinmoy Basak, Raghunath Ratabole
Discrete wavelet-based methods promise to emerge as an excellent framework for the non-perturbative analysis of quantum field theories. In this work, we investigate aspects of reno…
Quantum Mechanics in Wavelet Basis
Pavan Chawhan, Raghunath Ratabole
We describe a multi-scale resolution approach to analyzing problems in Quantum Mechanics using Daubechies wavelet basis. The expansion of the wavefunction of the quantum system in…
Comment on Phys. Rev. Lett. 109, 152005 (2012)
A. Harindranath, Rajen Kundu, Asmita Mukherjee +1
The identifications of transverse boost and rotation operators in light front theory done in Phys. Rev. Lett. {109}, 152005 (2012) is incorrect. The simple parton interpretation cl…
Instability in scalar channel of fermion-antifermion scattering amplitude in massless QED_3 and anomalous dimensions of composite operators
Indrajit Mitra, Raghunath Ratabole, H. S. Sharatchandra
Instability in the scalar channel of the fermion-antifermion scattering amplitude in massless QED_3 for number of flavours less than the critical value 128/3π^2 is demonstrated. Th…
