Toward Polyatomic Wave Packet Decomposition: Final State Effects†

Final State Interaction Effects in B+→J/ψ π+ Decay

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

Synchrosqueezed Wave Packet Transform for 2D Mode Decomposition

This paper introduces the synchrosqueezed wave packet transform as a method for analyzing twodimensional images. This transform is a combination of wave packet transforms of a certain geometric scaling, a reallocation technique for sharpening phase space representations, and clustering algorithms for modal decomposition. For a function that is a superposition of several wave-like components wit...

Geometric phase effects for wave-packet revivals.

The study of wavepacket revivals is extended to the case of Hamiltonians which are made time-dependent through the adiabatic cycling of some parameters. It is shown that the quantal geometric phase (Berry’s phase) causes the revived packet to be displaced along the classical trajectory, by an amount equal to the classical geometric phase (Hannay’s angle), in one degree of freedom. A physical ex...

Non - classical effects in wave packet dynamics

This is to certify that the thesis titled Non-classical effects in wave packet dynamics, submitted by C. Sudheesh to the Indian Institute of Technology Madras for the award of the degree of Doctor of Philosophy, is a bona fide record of the research work done by him under our supervision.
