In this thesis, we focused on studying how the background structure of spacetime a↵ects
quantum phenomena at micro and macroscopic levels [2, 11]. We also studied the possi-
bility that spacetime might be Euclidean at ...

This thesis explores ways in which quantum channels and correlations (of both classical
and quantum types) manifest themselves, and also studies the interplay between these two
aspects in various physical settings. Quantum ...

The variation of the measured (B^0 d − ((B^0)bar) d) mixing phase β/φ1 in b → cc(bar)s and
b → sq(bar)q (where q = u, d, s) modes is regarded as a possible probe of New
Physics. It has been speculated that this discrepancy ...
