Toward the demonstration of an avalanche THz photon detector with Rydberg atoms — •Fabio Bensch, Lea-Marina Steinert, Philip Osterholz, Shuanghong Tang, Arno Trautmann, and Christian Groß — Eberhard Karls Universität, Tübingen, Germany

Rydberg atoms confined within tweezers demonstrate unique capabilities in realizing strongly interacting and correlated many-body phenomena. The anti-blockade effect, notably, has proven to be an optimal tool for controlling non-linear avalanche Rydberg excitation in both disordered and ordered many-body systems. The integration of optical tweezers with advanced sorting algorithms enables the creation of defect-free arrays with highly precise geometry. In this context, we introduce a novel approach where the combination of defect-free arrays and avalanche facilitated excitation yields a straightforward and fuctional THz photon detector. This opens up an innovative utilization of Rydberg atoms to address the challenging issue of THz photon detection.
