Competition between structural and intrinsic dispersion in delay through a left handed medium
Dheeraj Golla, Subimal Deb, S Dutta Gupta
We study resonant tunneling through a layered medium with a negative index medium (NIM) slab as a constituent layer. We demonstrate large delays in transmission mediated by the sur…
Critical coupling in a system of two coupled negative index medium layers
Subimal Deb, S. Dutta Gupta
We study critical coupling (CC) in a system of two coupled negative index medium (NIM) layers leading to near-total suppression of both reflection and transmission at specified fre…
Better accuracy with fewer qubits: Single-particle basis set optimization for quantum chemistry on quantum computers
Subimal Deb, V. S. Prasannaa
In spite of recent advances, quantum computers are expected to be sufficiently noisy in the coming few years to the extent of limiting quantum chemical calculations to relatively s…
Applications of quantum annealing to magnetic dipole hyperfine structure constants: First results beyond energies for atoms
Boni Paul, Subimal Deb, Per Jönsson +2
We report the first results of the magnetic dipole hyperfine structure (HFS) constants of neutral , Li-like , neutral , and Na-like $\mathrm{…
Signature of strong atom-cavity interaction on critical coupling
Shourya Dutta Gupta, Subimal Deb, S. Dutta Gupta
We study a critically coupled cavity doped with resonant atoms with metamaterial slabs as mirrors. We show how resonant atom-cavity interaction can lead to a splitting of the criti…
Electro-optic modulation in a sub-wavelength gap-plasmon guide
Subimal Deb, K. Sarat Kumar, P. Anantha Lakshmi +1
We show efficient electro-optic modulation in a subwavelength gap-plasmon waveguide (GPW) formed by an electro-optic polymer with metal coatings. The proposed device is studied in…
