A liquid nitrogen cooled superconducting transition edge sensor with ultra-high responsivity and GHz operation speeds
Paul Seifert, Jose Ramon Duran Retamal, Rafael Luque Merino +9
Photodetectors based on nano-structured superconducting thin films are currently some of the most sensitive quantum sensors and are key enabling technologies in such broad areas as…

Magic-angle bilayer graphene nano-calorimeters -- towards broadband, energy-resolving single photon detection
P. Seifert, X. Lu, P. Stepanov +5
Because of the ultra-low photon energies in the mid-infrared and terahertz frequencies, in these bands photodetectors are notoriously underdeveloped, and broadband single photon de…

Spontaneous Transition to a Correlated Phase of Skyrmions Observed in Real Space
John N. Moore, Hikaru Iwata, Junichiro Hayakawa +4
We conduct photoluminescence microscopy that is sensitive to both electron and nuclear spin polarization to investigate the changes that occur in the magnetic ordering in the vicin…
