A new mechanism for gain in time dependent media
Sir John Pendry
Imperial College
Abstract: Energy can be added to electromagnetic waves in several different fashions. We identify a mechanism, distinct from conventional ones, in which compression of lines of force is the active ingredient. There are instances of this in other contexts: a superconductor repels magnets because the magnetic lines of forces are compressed as they are rejected by the superconductor. We show that in some circumstances the number of lines of force, electric and magnetic, in a time dependent system is conserved and amplification occurs when these lines of force are squeezed closer together.
Biography: John Pendry is a condensed matter theorist and has worked at Imperial since 1981. He began his career in the Cavendish Laboratory, Cambridge, followed by six years at the Daresbury Laboratory where he headed the theoretical group. He has worked extensively on electronic and structural properties of surfaces developing the theory of low energy diffraction and of electronic surface states. More recently he turned his attention to photonic materials this interest led to his present research into the remarkable electromagnetic properties of materials where the normal response to electromagnetic fields is reversed, leading to negative values for the refractive index. In collaboration with scientists at Marconi he designed a series of metamaterials, completely novel materials with properties not found in nature. These designs were subsequently the basis for new concepts with radical consequences, such as the first material with a negative refractive index and a prototype cloaking device, which have both caught the imagination of the world’s media.
The rise of Mie-tronics
Prof. Yuri Kivshar
ANU
Abstract: For many years, plasmonics was considered as the only suitable platform for subwavelength optics, but the recently emerged field of Mie resonant all-dielectric metaphotonics provides practical alternatives for nanoscale optics by employing resonances in high-index dielectric nanoparticles and metasurfaces. In this talk I aim to introduce this recently emerged field and discuss the physics of dielectric Mieresonant metamaterials for efficient spatial and temporal control of light by employing multipolar resonances and bound states in the continuum to achieve high values of the Q factor, with applications of these concepts to nonlinear optics, topological photonics, and sensing.
Biography: Yuri Kivshar received PhD degree in 1984 in Kharkov (Ukraine). From 1989 to 1993 he worked at several research centers in USA and Europe, and in 1993 he moved to Australia where he established Nonlinear Physics Center. His research interests include nonlinear physics, metamaterials, and nanophotonics. He is Fellow of the Australian Academy of Science, OSA, APS, SPIE, and IOP. He received many national and international awards including Pnevmatikos Prize in Nonlinear Science (Greece), Lyle Medal (Australia), Lebedev Medal (Russia), The State Prize in Science and Technology (Ukraine), Harrie Massey Medal (UK), Humboldt Research Award (Germany), and SPIE Mozi Award (USA).
Complementarity, Wave Particle Duality and Quantum Entanglement-Theory and Experiments
Prof. Girish Agarwal
TAMU
Abstract: We present an investigation of wave-particle duality for a photon that is generated from genuine point sources, i.e., a pair of nonlocally entangled two-level atoms. The point source nature justifies a free-space exact spherical wave treatment. More importantly, it allows a systematic quantitative analysis of the source effects on a quantum particle’s duality property. Surprisingly, duality is found to be a conditional phenomenon depending on the photon’s atomic source state. It can be tuned maximum, medium, and even minimum (completely absent) by the atomic state purity 𝜇s through an exact Pythagorean relation 𝜇s = 𝑉2 + 𝐷2 with visibility V and distinguishability D representing the photon’s wave and particle properties respectively. The visibility V also equals to the entanglement in the source state which translates into the path entanglement for the photon state. The results can be tested in various practical physical systems. We discuss a recent experimental work by Yoon and Cho that confirms our source-controlled duality relation. The experimental setup us based on the original work of Mandel and collaborators on inducing coherence by using single photons from two SPDC’s and by a clever use of the photon added coherent states.

Unconventional topological materials and phenomena
Prof. C. T. Chan
HKUST
Abstract: Recently, topological phases in condensed matter and photonic/phononic systems have captured the attention of scientists and engineers. These topological phases are usually classified by global topological invariants are usually integers, such as Chern numbers or winding numbers. We will use two examples to illustrate that we can have topological materials and topological phenomena that are not characterized by integers.
In the first example, we will see how non-Abelian topological charges (that behave like matrices) can be realized in some electromagnetic and acoustic systems, and the physical consequences that will arise. In fact, using non-Abelian quantities such as quaternions for the topological classification of material, such as disclination defects in liquid crystals, have preceded the current trend of using integers to classify topological materials.
In the second example, we will see that some simple photonic/phononic crystals which do not have bulk integer topological invariants behave like a "valley-Hall" topological crystal when certain boundary conditions are applied. Although the transport phenomena are almost indistinguishable from the valley-locked transport in valley-Hall crystals, the underlying principle is based on a boundary-condition induced bulk chiral anomaly, which cannot be classified using the usual topological invariants.
Biography: C.T. Chan received his PhD degree from the University of California at Berkeley in 1985. He is currently serving as the Associate Vice-President for Research & Development at HKUST.

He has been elected a Fellow of the American Physical Society and Hong Kong Physical Society.
High Dimensional Meta-devices: Classical to Quantum
Prof. DP Tsai
CityU HK
Abstract: Meta-surfaces are composed of an array of artificial nanostructures. The electromagnetic wave can be manipulated with its phase, polarization, and amplitude at will. Nowadays, the demand for photonics is extended from classical to quantum optics. With the advent of the post-Moore era, the fabrication technology of the semiconductor industry has faced the problem of the physical limitation approach. They have urgently needed to find out new methods and new physics to break through this dilemma. Quantum optics technology is the most suitable solution for this situation. Here, the design, fabrication, and application of the novel optical metadevices are reported from classical to quantum optics in this talk. The meta-lens array with achromatism is used to demonstrate a light field system for imaging and sensing. The integrated meta-lens array is used to demonstrate a high dimensional quantum light source chip with excellent performance of quantum fidelity.
