We derive an analogue of the Berry phase associated with inflationary cosmological perturbations of quantum mechanical origin by obtaining the corresponding wavefunction. We have further shown that cosmological Berry phase can be completely envisioned through the observable parameters, viz. spectral indices. Finally, physical significance of this phase is discussed from the point of view of theoretical and observational aspects with some possible consequences of this quantity in inflationary cosmology.

  1. Observation of Geometric Phase in a Molecular Aharonov-Bohm System Using IBM Quantum Computer

    quant-ph 2019-09 reject novelty 3.0 of 10

    The paper reports measuring a π geometric phase for a two-level Longuet-Higgins Hamiltonian on IBM quantum hardware, but the circuit is a direct rotation rather than an adiabatic simulation.
