Colossal power extraction from active cyclic Brownian information engines
Govind Paneru, Sandipan Dutta, Hyuk Kyu Pak
Brownian information engines can extract work from thermal fluctuations by utilizing information. So far, the studies on Brownian information engines consider the system in a therm…
Bona fide stochastic resonance under nonGaussian active fluctuations
Govind Paneru, Tsvi Tlusty, Hyuk Kyu Pak
We report on the experimental observation of stochastic resonance (SR) in a nonGaussian active bath without any periodic modulation. A Brownian particle hopping in a nanoscale doub…
Acceleration of enzymatic catalysis by active hydrodynamic fluctuations
Ashwani Kr. Tripathi, Tamoghna Das, Govind Paneru +2
The cellular milieu is teeming with biochemical nano-machines whose activity is a strong source of correlated non-thermal fluctuations termed active noise. Essential elements of th…
Transport and Diffusion Enhancement in Experimentally Realized Non-Gaussian Correlated Ratchets
Govind Paneru, Jin Tae Park, Hyuk Kyu Pak
Living cells are known to generate non-Gaussian active fluctuations significantly larger than thermal fluctuations owing to various active processes. Understanding the effect of th…
Rapid-Prototyping a Brownian Particle in an Active Bath
Jin Tae Park, Govind Paneru, Chulan Kwon +2
Particles kicked by external forces to produce mobility distinct from thermal diffusion are an iconic feature of the active matter problem. Here, we map this onto a minimal model f…
Efficiency fluctuations and noise induced refrigerator-to-heater transition in information engines
Govind Paneru, Sandipan Dutta, Takahiro Sagawa +2
Understanding noisy information engines is a fundamental problem of non-equilibrium physics, particularly in biomolecular systems agitated by thermal and active fluctuations in the…
Reaching and violating thermodynamic uncertainty bounds in information engines
Govind Paneru, Sandipan Dutta, Tsvi Tlusty +1
Thermodynamic uncertainty relations (TURs) set fundamental bounds on the fluctuation and dissipation of stochastic systems. Here, we examine these bounds, in experiment and theory,…
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…
Lossless Brownian information engine
Govind Paneru, Dong Yun Lee, Tsvi Tlusty +1
We report on a lossless information engine that converts nearly all available information from an error-free feedback protocol into mechanical work. Combining high-precision detect…
Optical damage threshold of Au nanowires in strong femtosecond laser fields
A. M. Summers, A. S. Ramm, Govind Paneru +3
Ultrashort, intense light pulses permit the study of nanomaterials in the optical non-linear regime, potentially leading to optoelectronics that operate in the petahertz domain. Th…
