    "abstract": "We study the stochastic dynamics of Brownian particles in a heat bath and\nsubject to an active feedback control by an external, Maxwell\u0027s demon-like\nagent. The agent uses the information of the velocity of a particle and reduces\nits thermal agitation by applying a force. The entropy of the particle and the\nheat bath as a whole, thus, reduces. Entropy pumping [Phys. Rev. Lett. 93,\n120602 (2004)] quantifies the entropy reduction. We discover that the entropy\npumping has a dual role of work and heat contributing to free energy changes\nand entropy production of the open-system with the feedback control.\nGeneralized Jarzynski equality and fluctuation theorems for work functional and\nentropy production are developed with the presence of the entropy pumping.",
