Instantaneous equilibrium Transport for Brownian systems under time-dependent temperature and potential variations: Reversibility, Heat and work relations, and Fast Isentropic process
Yonggun Jun, Pik-Yin Lai
The theory of constructing instantaneous equilibrium (ieq) transition under arbitrary time-dependent temperature and potential variation for a Brownian particle is developed. It is…
Optical tweezers as a mathematically driven spatio-temporal potential generator
John A. C. Albay, Govind Paneru, Hyuk Kyu Pak +1
The ability to create and manipulate the spatio-temporal potentials is essential in the diverse fields of science and technology. Here, we introduce an optical feedback trap system…
High-precision test of Landauer's principle in a feedback trap
Yonggun Jun, Momčilo Gavrilov, John Bechhoefer
We confirm Landauer's 1961 hypothesis that reducing the number of possible macroscopic states in a system by a factor of two requires work of at least kT ln 2. Our experiment uses…
Virtual potentials for feedback traps
Yonggun Jun, John Bechhoefer
The recently developed feedback trap can be used to create arbitrary virtual potentials, to explore the dynamics of small particles or large molecules in complex situations. Experi…
