Summary

Researchers demonstrate generating an observable geometric phase using incoherent phenomena. This involves adiabatically manipulating the environment, like a multilevel atom interacting with a squeezed vacuum bath, to imprint the phase.

Area of Science:

  • Quantum optics
  • Condensed matter physics
  • Atomic physics

Background:

  • Geometric phase is a fundamental concept in quantum mechanics.
  • Generating geometric phases typically requires coherent control.
  • Incoherent phenomena are usually associated with decoherence and loss of quantum information.

Purpose of the Study:

  • To propose a novel method for generating an observable geometric phase.
  • To demonstrate this generation through an incoherent phenomenon.
  • To explore the role of environmental manipulation in imprinting quantum phases.

Main Methods:

  • Adiabatic manipulation of the system's environment.
  • Analysis of a multilevel atom interacting with a broadband squeezed vacuum bosonic bath.

Related Experiment Videos

  • Smoothly varying squeezing parameters in time along a closed loop.

    • Main Results:

    • An observable geometric phase is generated via an incoherent process.
    • The ground state of the multilevel atom acquires a geometric phase.
    • A scheme for measuring the geometric phase using polarization detection is proposed.

    Conclusions:

    • Geometric phases can be generated and observed through incoherent environmental interactions.
    • Adiabatic manipulation of the environment offers a new route to quantum phase imprinting.
    • The proposed scheme provides a practical method for detecting these phases.
