Topological optical skyrmion transfer to matter
Chirantan Mitra, Chetan Sriram Madasu, Lucas Gabardos +4
The ability of structured light to mimic exotic topological skyrmion textures, encountered in high-energy physics, cosmology, magnetic materials, and superfluids has recently recei…
Experimental realization of a SU(3) color-orbit coupling in an ultracold gas
Chetan S. Madasu, Chirantan Mitra, Lucas Gabardos +6
Spin-orbit interaction couples the spin of a particle to its motion and leads to spin-induced transport phenomena such as spin-Hall effects and Chern insulators. In this work, we e…
Geometric Ramsey Interferometry with a Tripod Scheme
Chetan Sriram Madasu, Ketan Damji Rathod, Chang Chi Kwong +1
Ramsey interferometry is a key technique for precision spectroscopy and to probe the coherence of quantum systems. Typically, an interferometer is constructed using two quantum sta…
Evolution of an ultracold gas in a non-Abelian gauge fields: Finite temperature effect
Mehedi Hasan, Chetan Sriram Madasu, Ketan D. Rathod +2
We detail the cooling mechanisms of a Fermionic strontium-87 gas in order to study its evolution under a non-Abelian gauge field. In contrast to our previous work reported in Ref.…
Datta-Das transistor for atomtronic circuits using artificial gauge fields
Chetan Sriram Madasu, Mehedi Hasan, Ketan D. Rathod +2
Spin-dependent electrical injection has found useful applications in storage devices, but fully operational spin-dependent semiconductor electronics remain a challenging task becau…
Wave-packet Dynamics in Synthetic Non-Abelian Gauge Fields
Mehedi Hasan, Chetan Sriram Madasu, Ketan D. Rathod +4
It is generally admitted that in quantum mechanics, the electromagnetic potentials have physical interpretations otherwise absent in classical physics as illustrated by the Aharono…
Homodyne detection of a two-photon resonance assisted by cooperative emission
Chetan Sriram Madasu, Chang Chi Kwong, David Wilkowski +1
Focusing on the transient regime, we explore atomic two-photon spectroscopy with self-aligned homodyne interferometry in a -system with large optical depth. The two light source…
