    "abstract": "Transport of a Brownian particle moving in a periodic potential is\ninvestigated in the presence of symmetric unbiased external force. The viscous\nmedium is alternately in contact with the two heat reservoirs. We present the\nanalytical expression of the net current at quasi-steady state limit. It is\nfound that the competition of the asymmetric parameter of potential with the\ntemperature difference leads to the phenomena like current reversal. The\ncompetition between the two driving factors is a necessary but not a sufficient\ncondition for current reversals.",
