  1. Quantum Coherent Transport in Atoms & Electrons

    21 Jun 2017 | Online Presentations | 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...

  2. Novel Plasmonic Materials and Nanodevices for Integrated Quantum Photonics

    19 Jun 2017 | Online Presentations | 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...

  3. Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials

    08 Jun 2017 | Online Presentations | 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...

  6. What is Markovian and non-Markovian in Quantum Mechanics: New Approaches and Viewpoints

    15 May 2017 | Online Presentations | 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)...
