  1. Tutorial on Two Photon Lithography Tool

    26 Nov 2018 | Online Presentations

    Two-photon lithography (TPL) is a nano-scale 3-d fabrication technique. TPL depends upon the two-photon 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...

  14. What is Markovian and non-Markovian 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 non-Markovian (NM)? Traditional answers to this question involve the celebrated Lindblad master equation (ME)...
