Collective Enhancement of Photon Blockade via Two-Photon Interactions
Lijuan Dong, Aanal Jayesh Shah, Peter Kirton +2
Analogous to Coulomb blockade for electrons, photon blockade is a key quantum optical effect in which the presence of one photon prevents the transmission of subsequent ones throug…

Dissipative Phase Transition in the Two-Photon Dicke Model
Aanal Jayesh Shah, Peter Kirton, Simone Felicetti +1
We explore the dissipative phase transition of the two-photon Dicke model, a topic that has garnered significant attention recently. Our analysis reveals that while single-photon l…

Superfluorescent upconversion nanoparticles as an emerging second generation quantum technology material
Lewis E. MacKenzie, Peter Kirton
Superfluorescence (SF) in lanthanide doped upconversion nanoparticles (UCNPs) is a room-temperature quantum phenomenon, first discovered in 2022. In a SF process, the many emissive…
