Efficient ensemble randomization by tuning chaos in a nonlinear spin-1 system
Jongmin Kim, Minsung Jeong, Jongyoon Han +1
We present an efficient scheme to randomize a spin-state ensemble in a nonlinear spin-1 system by tuning chaos with an external periodic drive. Without modulation, the system exhib…
Enhancement of damping in a turbulent atomic Bose-Einstein condensate
Junghoon Lee, Jongmin Kim, Jongheum Jung +1
Turbulence enhances momentum transport in classical fluids, effectively increasing their viscosity. We investigate an analogous effect in a superfluid by measuring the damping of c…
Dual-species atomic absorption image reconstruction using deep neural networks
Kyuhwan Lee, Yong-il Shin
Optical imaging plays an instrumental role in understanding the behavior of trapped neutral atoms. In this work, we describe a deep learning-based online image completion protocol…
The thermodynamics of CaSiO3 in Earth's lower mantle
Yongjoong Shin, Enrico Di Lucente, Nicola Marzari +1
The lower mantle of Earth, characterized by pressures of 24-127 GPa and temperatures of 1900-2600 K, is still inaccessible to direct observations. In this work, we investigate by f…
