Equilibration of the planar modes of ultracold two dimensional ion crystals in a Penning trap

Chen Tang, Athreya Shankar, Dominic Meiser +3

Planar thermal equilibration is studied using direct numerical simulations of ultracold two-dimensional (2D) ion crystals in a Penning trap with a rotating wall. The large magnetic…

Subradiant-to-Subradiant Phase Transition in the Bad Cavity Laser

Athreya Shankar, Jarrod T. Reilly, Simon B. Jäger +1

We show that the onset of steady-state superradiance in a bad cavity laser is preceded by a dissipative phase transition between two distinct phases of steady-state subradiance. Th…

Regular and bistable steady-state superradiant phases of an atomic beam traversing an optical cavity

Simon B. Jäger, Haonan Liu, Athreya Shankar +2

We investigate the different photon emission regimes created by a preexcited and collimated atomic beam passing through a single mode of an optical cavity. In the regime where the…

Broadening of the drumhead mode spectrum due to in-plane thermal fluctuations of two-dimensional trapped ion crystals in a Penning trap

Athreya Shankar, Chen Tang, Matthew Affolter +5

Two-dimensional crystals of ions stored in Penning traps are a leading platform for quantum simulation and sensing experiments. For small amplitudes, the out-of-plane motion of suc…

Squeezed state metrology with Bragg interferometers operating in a cavity

Athreya Shankar, Leonardo Salvi, Maria Luisa Chiofalo +2

Bragg interferometers, operating using pseudospin-1/2 systems composed of two momentum states, have become a mature technology for precision measurements. State-of-the-art Bragg in…

Modeling near ground-state cooling of two-dimensional ion crystals in a Penning trap using electromagnetically induced transparency

Athreya Shankar, Elena Jordan, Kevin A. Gilmore +3

Penning traps, with their ability to control planar crystals of tens to hundreds of ions, are versatile quantum simulators. Thermal occupations of the motional drumhead modes, tran…
