Continuous Narrow-Linewidth Superradiance in Waveguide QED
Anna Bychek, Martin Fasser, Ivan Vybornyi +4
Superradiant lasers promise continuous, narrow-linewidth coherent emission at the bare atomic transition frequency, enabling frequency references of exceptional precision. Recent e…
Collective enhancement in sideband cooling of ion crystals
Ivan Vybornyi, Artem Zhdanov, Matthias Bock +4
Low-entropy motional states of ion Coulomb crystals are an essential prerequisite for a plethora of applications and are typically prepared by laser cooling. As larger crystals are…
Line search by quantum logic spectroscopy enhanced with squeezing and statistical tests
Ivan Vybornyi, Shuying Chen, Lukas J. Spieà +2
In quantum logic spectroscopy, internal transitions of trapped ions and molecules can be probed by measuring the motional displacement caused by an applied light field of variable…
Identification of highly-forbidden optical transitions in highly charged ions
Shuying Chen, Lukas J. SpieÃ, Alexander Wilzewski +6
Optical clocks represent the most precise experimental devices, finding application in fields spanning from frequency metrology to fundamental physics. Recently, the first highly c…
