We propose a scheme to demonstrate the manipulation of space-dependent four-wave
mixing (FWM) in a four-level atomic system. By adjusting the detuning of the control field …

We present spectroscopy of a single Rydberg atom excited within a Bose-Einstein
condensate. We not only observe the density shift as discovered by Amaldi and Segrè in …

We describe a theoretical investigation of a four-wave mixing (FWM) scheme in a six-level
atomic system driven by a field with orbital angular momentum and making use of two …

This PhD tutorial discusses ultra-long-range Rydberg molecules, the exotic bound states of
a Rydberg atom and one or more ground state atoms immersed in the Rydberg electron's …

Impurity physics is a traditional topic in condensed matter physics that nowadays is being
explored in the field of ultracold gases. Among the different classes of impurities, we focus …

We demonstrate that Ramsey spectroscopy can be used to observe Rydberg-dressed
interactions in a many-body system well within experimentally measured lifetimes, in …

Resonant laser excitation of multiple Rydberg atoms are prohibited, leading to Rydberg
blockade, when the long-range van der Waals interactions are stronger than the laser-atom …

We propose a scheme to control quantum coherence of a two-component Bose–Einstein
condensate (BEC) by a single impurity atom immersed in the BEC. We show that the single …

This work presents a theoretical analysis of the helical phase steering via a four-wave
mixing (FWM) process in a closely cycled double-ladder atomic system. Our focus is to …

We often infer the state of systems in nature indirectly, for example, in high-energy physics
by the interaction of particles with an ambient medium. We adapt this principle to energies 9 …
