26 Nov 2018   Contributor(s):: Mohammad Mahfuzul Kabir, Varun Ajit Kelkar
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...

Quantum Coherent Transport in Atoms & Electrons
21 Jun 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
19 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, singlephoton sources, and quantum memories. In particular, we explored an intriguing...

Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials
08 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...

Soft, Biocompatible Optoelectronic Interfaces to the Brain
08 Jun 2017   Contributor(s):: John A. Rogers
In this talk, we will describe foundational concepts in physics and materials science for these types of technologies, in 1D, 2D and 3D architectures. Examples in system level demonstrations include experiments on freely moving animals with ‘cellularscale’, injectable optofluidic...

What is Markovian and nonMarkovian in Quantum Mechanics: New Approaches and Viewpoints
15 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 nonMarkovian (NM)? Traditional answers to this question involve the celebrated Lindblad master equation (ME)...

Laser Filtering, Metamaterials, and Commercializing Through the Lens of the Mythical Person Month
09 Jan 2017   Contributor(s):: Themos Kallos
In this work we investigate whether optical metamaterials in particular may require more than the typical resources to lead to successful commercialization. We also compare the estimated efforts with other technology commercialization projects of the recent past. ...

Photonic Structures with Topological Robustness: from Classical to Quantum
09 Jan 2017   Contributor(s):: Mohammad Hafezi
In this talk, I demonstrate how similar physics can be observed for photons; specifically, how various quantum Hall Hamiltonians can be simulated in an optical platform. I report on the first observation of topological photonic edge state using silicononinsulator technology and our recent...
