In a previous paper [B. Deb and G. S. Agarwal, Phys. Rev. A 90, 063417 (2014)], it was theoretically shown that, magneto-optical manipulation of low energy scattering resonances and atom-molecule transitions could lead to the formation of a bound state in continuum (BIC), provided there is no spontaneous emission. We find that even an exceedingly small spontaneous decay from exited molecular states can spoil the BIC. In this paper, we show how to circumvent the detrimental effect of spontaneous…

A Simplified Laser System for Atom Interferometry Based on a Free-Space EOM
In this paper, a compact laser system for 87Rb atom interferometry based on only one free-space electro-optic modulator (EOM) was realized, where repumping and Raman beams were generated with a


Creation and manipulation of bound states in the continuum with lasers: Applications to cold atoms and molecules
We show theoretically that it is possible to create and manipulate a pair of bound states in continuum in ultracold atoms by two lasers in the presence of a magnetically tunable Feshbach resonance.
Observation of trapped light within the radiation continuum
It is predicted and shown experimentally that light can be perfectly confined in a patterned dielectric slab, even though outgoing waves are allowed in the surrounding medium.
Lasing action from photonic bound states in continuum
Results show that the lasing wavelength of the fabricated BIC cavities, each made of an array of cylindrical nanoresonators suspended in air, scales with the radii of the nanoreonators according to the theoretical prediction for the BIC mode, and lasing action from the designed BIC cavity persists even after scaling down the array to as few as 8-by-8 nanoreisonators.

In a recent experiment by Yamazaki {\it et al.} [Phys.Rev. A {\bf 87} 010704 (R) (2013) ], $p$-wave optical Feshbach resonance in fermionic $^{171}$Yb atoms using purely long-range molecular excited
Control of resonant interaction between electronic ground and excited states.
Analysis of the on-site interaction of doubly occupied sites of an atomic Mott-insulator state in a three-dimensional optical lattice as a collisional frequency shift in a high-resolution laser spectroscopy reveals a wide variation of the interaction around a magnetic field.
Observation of an electronic bound state above a potential well
SHORTLY after the birth of quantum mechanics, von Neumann and Wigner made the remarkable proposal1 that certain spatially oscillating attractive potentials could support bound states at energies
Long-lived quasistationary coherences in a V-type system driven by incoherent light.
It is found that in the opposite limit of small level spacing Δ/γ≪1, appropriate for large molecules, the coherences can survive for an extremely long time τ=(2/γ)(Δ/γ)^{-2} before eventually decaying to zero, and coherences at short times can be substantial.
Long-lived quantum coherences in a V -type system strongly driven by a thermal environment
We explore the coherent dynamics of a three-level V-system interacting with a thermal bath in the regime where thermal excitation occurs much faster than spontaneous decay. We present analytic
Two-dimensional Fano lineshapes: Excited-state absorption contributions.
It is found that the characteristic asymmetry of one-dimensional spectroscopies is recovered from the many-body contributions and that the higher lying excited manifolds have distorted lineshapes that are not anticipated from discrete-level Hamiltonians.

It is shown that population can be trapped within the model atom even when radiative decay is included provided the two Fano q values which characterize the discrete-state-continuum interactions are equal, and the two-photon resonance condition is satisfied.
