| Research Abstract |
We have investigated an nonequilibrium transport in a molecular chain, such as alpha-helix, which is interacting with different thermal baths at the both molecular ends. An energy flow and vibrational exciton current under nonequilibrium steady state are obtained based on the microscopic dynamics as a zero eigenstate of a Liouville operator. The phenomenological Landauer formula has been derived from our theory and the limit of the phenomenological formula has been revealed.
