Parviz ElahiÖzyeğin University, Istanbul “Fiber Lasers: From Elemental Analysis to Smart Agriculture” AbstractFiber lasers have become versatile tools for scientific and industrial applications, offering high efficiency and precise control over laser parameters. In this talk, I will present our recent research that connects laser–matter interactions to three applications. First, I will discuss laser-induced breakdown spectroscopy…

Itır KöymenTOBB ETÜ, Ankara “Memristive dynamics: resistive switching, quantum conductance and parallels with weak inversion MOS transistor dynamics” AbstractEmerging devices have become the focus of considerable research activity as Complementary Metal-Oxide-Semiconductor (CMOS) scaling approaches its practical limits. To meet growing computational demands, beyond-CMOS devices and alternatives to conventional von Neumann architectures are being investigated. Memristive…

Peng XueSoutheast University, China “Non-Hermitian Quantum Walks and Applications” AbstractThis talk presents non-Hermitian quantum walks and their applications in quantum optical systems. Quantum walks are realized with single-photon polarization and spatial modes, and non-Hermitian Hamiltonians are constructed via controllable gain and loss. We experimentally observe PT-symmetry breaking, exceptional-point behavior, and the non-Hermitian skin effect, confirming…

Leyla Çolakerol ArslanGebze Technical University“Laser-driven engineering of vacancy and color-center defects in diamond” Abstract Nitrogen-vacancy (NV) and silicon-vacancy (SiV) centers in diamond are promising platforms for quantum sensing, photonics, and emerging quantum technologies, but their controlled formation and spatial engineering remain challenging. We investigate nanosecond-pulsed 1064 nm laser defect engineering in type IIa CVD diamond…

BİLKENT UNIVERSITY, DEPARTMENT of PHYSICS Burak GüzeltürkArgonne National Laboratory “Light-Driven Control of Quantum Materials” AbstractMany of the most intriguing properties of quantum materials, including ferroicity, correlated electronic order, and adaptive functionality, emerge from a delicate interplay between charge, lattice, spin, and orbitals. Under equilibrium conditions, these competing interactions often constrain materials to a limited set…

Mustafa GündoğanHumboldt University of Berlin “Quantum Memories for Space-Based Quantum Networks and Quantum Sensing” AbstractQuantum memories are key components of quantum networks, providing coherent storage and synchronization of photonic quantum states. In the first part of this talk, I will discuss our work on extending quantum memories towards space-based quantum networks, including architectures in which…
