Cavity optomechanical detection of persistent currents and solitons in a bosonic ring condensate
Nalinikanta Pradhan, Pardeep Kumar, Rina Kanamoto +3
We present numerical simulations of the cavity optomechanical detection of persistent currents and bright solitons in an atomic Bose-Einstein condensate confined in a ring trap. Th…
Ultrafast valley polarization in bilayer graphene
Pardeep Kumar, Thakshila M. Herath, Vadym Apalkov
We study theoretically interaction of a bilayer graphene with a circularly polarized ultrafast optical pulse of a single oscillation at an oblique incidence. The normal component o…
Bilayer graphene in strong ultrafast laser fields
Pardeep Kumar, Thakshila M. Herath, Vadym Apalkov +1
We theoretically investigate the interaction of an ultrastrong femtosecond-long linearly polarized optical pulse with AB-stacked bilayer graphene. The pulse excite electrons from t…
Single-photon transfer using levitated cavityless optomechanics
Pardeep Kumar, M. Bhattacharya
We theoretically explore a quantum memory using a single nanoparticle levitated in an optical dipole trap and subjected to feedback cooling. This protocol is realized by storing an…
Population trapping in the excited states using vacuum-induced coherence and adiabatic process
Babu Lal Kumawat, Pardeep Kumar, Shubhrangshu Dasgupta
We theoretically investigate how population can be trapped in the excited doublet in presence of vacuum-induced coherence (VIC). We employ delayed pulses to transfer population fro…
Magnetometry via spin-mechanical coupling in levitated optomechanics
Pardeep Kumar, M. Bhattacharya
We analyze magnetometry using an optically levitated nanodiamond. We consider a configuration where a magnetic field gradient couples the mechanical oscillation of the diamond with…
