Quantum Physics Research
My academic journey began with a fascination for optics and quantum mechanics during my bachelor's studies, where I designed a Michelson interferometer as my first step into experimental physics. This experience inspired me to pursue a master's degree in photonics, where I explored experimental laser physics and nonlinear optics. During my thesis, I designed and fabricated several types of fiber and bulk lasers, including a high-power 532 nm laser based on resonant second harmonic generation — published in the International Journal of Optics and Photonics.
I also broadened my experience by collaborating with Masih Daneshvari Hospital in Tehran, where I modeled brain tissue for the development of a tumor-treating fields (TTF) device. In 2023, I joined TU Wien as a PhD researcher and project assistant, contributing to CANNEX — a force-metrology experiment at the intersection of quantum mechanics and cosmology. This project explores dark energy, dark matter, and quantum gravity interactions, while also investigating Casimir forces and force gradients as windows into the quantum vacuum. Driven by curiosity and a passion for experimentation, I aim to bridge fundamental physics with innovative applications.

Applied computational modeling for tumor treating fields (TTF) therapy optimization using 3D MRI segmentation and dielectric modeling.
Advancing the CANNEX experiment with cryogenic actuation, sub-picometer interferometry, and electrostatic compensation to probe exotic quantum vacuum interactions.
The 1.8 m tall CANNEX instrument nests a thermally controlled silica reference plate beneath a silicon single-crystal force sensor. Three 200 µm-range linear piezos trim the plate parallelism while fiber-coupled interferometers and a drift-free optical cavity track plate spacing and tilt with sub-nanometer fidelity. Non-contact thermal shrouds and stick-slip positioning stages stabilise the sensor stack, enabling operation in both direct interfacial and shielded Cavendish configurations for dark-sector and Casimir-force searches.[1]
The core chamber is suspended within nested vacuum shells and cooled via guided copper heat exchangers before coupling to a six-axis seismic attenuation system. An inverted pendulum, a geometric anti-spring filter, and tuned mass tower suppress horizontal, vertical, and tilt motion respectively, while geophones and linear variable differential transformers monitor residual drift for feed-forward control. This integrated stack maintains <10-9 mbar pressure and sub-µK thermal gradients, delivering the force sensitivity roadmap outlined for upcoming CANNEX campaigns.[1]
