Recently, interdisciplinary exchanges among condensed matter physics, quantum field theory, quantum information, and cosmology have been advancing, with quantum geometry as a central theme. These interactions have led to the development of novel physical concepts. This workshop provides a valuable opportunity to create an open forum for the free exchange of ideas, fostering a broader perspective across these interdisciplinary fields.
We invite researchers from various fields—including quantum vacuum and Casimir physics, black hole Hawking radiation, quantum dissipation, quantum geometry, and both theoretical and experimental quantum optics—to come together and explore new directions at the crossroads of modern physics.
