Direct visualization of defect-controlled diffusion in van der Waals gaps
Joachim Dahl Thomsen, Yaxian Wang, Henrik Flyvbjerg +5
Diffusion processes govern fundamental phenomena such as phase transformations, doping, and intercalation in van der Waals (vdW) bonded materials. Here, we quantify the diffusion d…
Harmonic Oscillator in Heat Bath: Exact simulation of time-lapse-recorded data, exact analytical benchmark statistics
Simon F. Norrelykke, Henrik Flyvbjerg
The stochastic dynamics of the damped harmonic oscillator in a heat bath is simulated with an algorithm that is exact for time steps of arbitrary size. Exact analytical results are…
Power spectrum analysis with least-squares fitting: Amplitude bias and its elimination, with application to optical tweezers and atomic force microscope cantilevers
Simon F. Norrelykke, Henrik Flyvbjerg
Optical tweezers and AFM cantilevers are often calibrated by fitting their experimental powerspectra of Brownian motion. We demonstrate here that if this is done with typical weigh…
Resonant effects in a voltage-activated channel gating
Ewa Gudowska-Nowak, Bartlomiej Dybiec, Henrik Flyvbjerg
The non-selective voltage activated cation channel from the human red cells, which is activated at depolarizing potentials, has been shown to exhibit counter-clockwise gating hyste…
Brownian Motion after Einstein: Some new applications and new experiments
David Selmeczi, Simon F. Tolic-Norrelykke, Erik Schaeffer +5
The first half of this chapter describes the development in mathematical models of Brownian motion after Einstein's seminal papers and current applications to optical tweezers. Thi…
Power Spectrum Analysis for Optical Tweezers, II: Laser Wavelength Dependence of Parasitic Filtering, and how to Achieve High Band-Width
Kirstine Berg-Sorensen, Erwin J. G. Peterman, Tom Weber +2
In a typical optical tweezers detection system, the position of a trapped object is determined from laser light impinging on a quadrant photodiode. When the laser is infrared and t…
