Low-Energy Purification of Crystal Defects by Rydberg Excitons
Shiva Kant Tiwari, Tijs Karman, Valentin Walther
Recent experiments show that optically generated Rydberg excitons in cuprous oxide can neutralize charged impurities, strongly reducing stray electric fields and effectively purify…

Generation and decoherence of soliton spatial superposition states
Abhijit Pendse, Shruti Shirol, Shivakant Tiwari +1
Due to their coherence properties, dilute atomic gas Bose-Einstein condensates seem a versatile platform for controlled creation of mesoscopically entangled states with a large num…

Tracking Rydberg atoms with Bose-Einstein Condensates
Shiva Kant Tiwari, Sebastian Wüster
We propose to track position and velocity of mobile Rydberg excited impurity atoms through the elastic interactions of the Rydberg electron with a host condensate. Tracks first occ…
