Maximizing power and velocity of an information engine
Tushar K. Saha, Joseph N. E. Lucero, Jannik Ehrich +2
Information-driven engines that rectify thermal fluctuations are a modern realization of the Maxwell-demon thought experiment. We introduce a simple design based on a heavy colloid…
Dual-mode optical fiber-based tweezers for robust trapping and manipulation of absorbing particles in air
Souvik Sil, Tushar Kanti Saha, Avinash Kumar +2
We develop an optical tweezers system using a single dual-mode optical fiber where mesoscopic absorbing particles can be trapped in three dimensions and manipulated employing photo…
Simultaneous measurement of mass and rotation of trapped absorbing particles in air
Sudipta K. Bera, Avinash Kumar, Souvik Sil +3
We trap absorbing micro-particles in air by photophoretic forces generated using a single loosely focused Gaussian trapping beam. We measure a component of the radial Brownian moti…
