An externally-corrected size-extensive single-root MRCC formalism: its kinship with the rigorously size-extensive state-specific MRCC theory
TL;DR: An externally corrected size-extensive single-root multi-reference CC (ecsr-MRCC) formalism is proposed, which is intruder-free and simpler in structure as compared to the parent SSMRCC theory.
Journal ArticleDOI
Localization in some discontinuously and randomly driven quantum systems
TL;DR: In this article, it is shown that a charged particle moving in a harmonic, symmetric double well, a square well, or a Morse potential is allowed to interact with a discontinuously reversing spatially homogeneous electric field.
Journal ArticleDOI
Coherent destruction of tunneling with optimally designed polychromatic external field
TL;DR: In this paper, a polychromatic field with a very low field strength and low frequency ( ∼ 10 - 5 atomic unit) can bring about coherent destruction of tunneling (CDT) in a symmetric double well system.
Journal ArticleDOI
Picosecond Bessel Beam Fabricated Pure, Gold-Coated Silver Nanostructures for Trace-Level Sensing of Multiple Explosives and Hazardous Molecules
TL;DR: In this article , a zeroth-order non-diffracting Bessel beam, generated by picosecond laser pulses (1064 nm, 10 Hz, 30 ps) through an axicon, was utilized to perform pulse energy-dependent ablation of silver (Ag) substrates in air.
Journal ArticleDOI
Bichromatic fluctuations in symmetric double well potentials: Localization and control of tunneling
TL;DR: In this paper, the effects of spatial symmetry-preserving bichromatic fluctuations in symmetric double well systems were studied and the analysis was done using the Floquet technique and the time-dependent Hellmann-Feynman theorem.
