Tutorial on Two Photon Lithography Tool
26 Nov 2018  Online Presentations
Twophoton lithography (TPL) is a nanoscale 3d fabrication technique. TPL depends upon the twophoton polymerization process, whereby two incident photons of light are absorbed by a precursor material leading to polymerization. The smallest feature size (voxel) achievable in a TPL...

What is Markovian and nonMarkovian in Quantum Mechanics: New Approaches and Viewpoints
29 Nov 0001  Online Presentations
While in classical physics the notion of what is Markovian or not is well defined, this is not the case when it comes to open quantum systems. What makes a quantum dynamics Markovian or nonMarkovian (NM)? Traditional answers to this question involve the celebrated Lindblad master equation (ME)...
