Rydberg-State Hopping in a Wavemeter-Locked Dissipative Time-Crystal System
Darmindra Arumugam
Rydberg-state hopping is demonstrated in a wavemeter-locked two-photon rubidium system (Rb D2 probe at 780 nm and 480 nm coupler), enabling rapid and repeatable switching between t…
Stabilization of Rydberg Dissipative Time Crystals Using a Scanning Fabry Perot Interferometer Transfer Lock
Darmindra Arumugam, Brook Feyissa
Stabilization of laser frequencies is critical for sensitive Rydberg measurements, including in applications such as dissipative time crystal (DTC) dynamics, yet conventional appro…
Stark-modulated Rydberg dissipative time crystals at room-temperature applied to sub-kHz electric-field sensing
Darmindra Arumugam
Out-of-equilibrium Rydberg gases exhibit emergent many-body phases due to mode competition. Sustained limit cycle oscillations (OSC) emerge when driven by B-fields at room-temperat…
Electric-field sensing with driven-dissipative time crystals in room-temperature Rydberg vapor
Darmindra Arumugam
Mode competition in nonequilibrium Rydberg gases enables the exploration of emergent many-body phases. This work leverages this emergent phase for electric field detection at room…
