Quantum computation in decoherence-free subspace via cavity-decay-assisted adiabatic passage
The scalar phantom field <i>Φ</i> leads to various catastrophic fates of the universe including big rip,little rip and other future singularity depending on the choice of its potential.For example,little rip stems from a quadratic potential in general relativity.We suggest a new mechanis...

| Summary: | The scalar phantom field <i>Φ</i> leads to various catastrophic fates of the universe including big rip,little rip and other future singularity depending on the choice of its potential.For example,little rip stems from a quadratic potential in general relativity.We suggest a new mechanism to avoid little rip in the 1/<i>R</i> gravity.The phantom field with different potentials,including quadratic,cubic and quantic potentials are studied via numerical calculation in the 1/<i>R</i> gravity with <i>R</i><sup>2</sup> correction.The singularity is avoidable under all these potentials. |
