When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

Tutorial on Two Photon Lithography Tool
26 Nov 2018 | | Contributor(s):: Mohammad Mahfuzul Kabir, Varun Ajit Kelkar
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...

What is Markovian and non-Markovian in Quantum Mechanics: New Approaches and Viewpoints
12 May 2017 | | Contributor(s):: Francesco Ciccarello
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)...
