theoretically calculated numbers is excellent and directly justifies our exact calculations. In most of the BR models actual structural realities like volume exclusion etc are masked due to considering the system as a structureless particle. Moreover, considering a repeated setup of asymmetric microscopic potentials in 1D is also in effect a macroscopic symmetry breaking that results in macroscopic directional transport. With the help of the present model, we explicitly show that in 1D there is no need for such macroscopically broken symmetry present for the transport to happen. Considering the internal structure of the microscopic moving system, we show that the volume exclusion would actually make the microscopic broken symmetry remain intact over all the time in 1D where there is no ro- tational degrees of freedom. Thus, the direction of motion picked up by the system will be there for ever if the nature of the instantaneous velocity feedback remains the same. In this connection a discussion of the role of the feedback term in our model is worth doing. In effect, the feedback term is serving two purposes - it breaks the symmetry and drives the system out of equilibrium. Actually, for β > 0, 1. it reduces the damping experienced by the particle at x$_{1}$ and 2. it makes the temperature of the particle at x$_{1}$ different from that at x$_{2}$ (which is a non-equilibrium situation ensuring possibility of heat flow between the parts of the system). A change in the sign of β would do the same but in a way so that the particle at x$_{2}$ would now be in the driver’s seat by having smaller damping and larger temperature. The different damping experienced by two different particles could be because of two differently shaped bodies sitting at x$_{1}$ and x$_{2}$ and the difference in temperature could be due to the fact that one of them is being driven by some unbiased force. Within the present feedback picture, we do not need to take the shape of the objects at positions x$_{1}$ and x$_{2}$ into consideration, rather take them as particles. However, taking these two essen- tial requirements like symmetry breaking and the driving in a correlated way through the velocity feedback is obviously a restriction. But, it nicely allows us to do a simple exact analytic calculation for the system to explicitly understand the interplay of the elasticity and volume exclusion to generate directional transport. An extension of the system in 2D, where rotational degrees of freedom are present, is straight forward [17] and it can generally capture the principle of transport of some bacterial systems.
