title: Dynamical phase transition of a periodically driven DNA.
abstract: Replication and transcription are two important processes in living systems. To execute such processes, various proteins work far away from equilibrium in a staggered way. Motivated by this, aspects of hysteresis during unzipping of DNA under a periodic drive are studied. A steady-state phase diagram of a driven DNA is proposed which is experimentally verifiable. As a two-state system, we also compare the results of DNA with that of an Ising magnet under an asymmetrical variation of the magnetic field.
