  6. Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials

    29 Nov -0001 | Online Presentations

    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...

  7. Soft, Biocompatible Optoelectronic Interfaces to the Brain

    29 Nov -0001 | Online Presentations

    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 ‘cellular-scale’, injectable optofluidic...

  8. 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)...
