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.

Quantum Coherent Transport in Atoms & Electrons
25 May 2017 | | Contributor(s):: Yong P. Chen
I will discuss some recent experimental examples from my lab studying quantum coherent transport and interferometry in electrons as well as cold atoms. For example, phase coherent electron transport and interference around a cylinder realized in a nanowire of topological insulator...
Novel Plasmonic Materials and Nanodevices for Integrated Quantum Photonics
07 Jun 2017 | | Contributor(s):: Mikhail Shalaginov
This research focuses on color centers in diamond that share quantum properties with single atoms. These systems promise a path for the realization of practical quantum devices such as nanoscale sensors, single-photon sources, and quantum memories. In particular, we explored an intriguing...
Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials
07 Jun 2017 | | Contributor(s):: Alexander K. Popov
Coherence and interference play an important role in classic and quantum physics. Processes to be employed can be significantly enhanced and the unwanted ones suppressed through the deliberately tailored constructive and destructed interference at quantum transitions and at nonlinear optical...

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)...
