Quantum-mechanical theory of optical coherence - Laser-based precision spectroscopy and optical frequency comb techniques General introduction Light provides the most pertinent example of the dual nature of quantum objects; its oscillatory properties served to verify the electromagnetic theory of Maxwell, and its lumpiness, the photons, signalled the dawn of modern quantum theory.

Here, the intensity (I$_1$) of the first pump pulse P$_1$ is $4\times 10^{13}$W/cm$^{2}$, the rotational temperature is 100 K. As shown in Fig. E. Gershnabel and I. S. Averbukh, “Deflection of Field-Free Aligned Molecules,” Phys. Figure 2 depicts simulated results of the full (blue circle), 1/2 (green diamond) and 1/3 (red cross) alignment echoes for three different time delays of $\Delta \tau =0.05$ T$_{rev}$ [Fig. Rev. As $\Delta \tau$ deviates from T$_{rev}/8$, the vanishing constructive interference will lead to the decrease of the alignment echo intensity. K. A. K. Lin, P. Lu, J. Ma, X. Gong, Q. Rev. S. Fleischer, Y. Khodorkovsky, Y. 9. Quantum control exploits these phenomena using controlled coherent interactions to direct the dynamics of quantum systems. Citing articles from OSA journals and other participating publishers are listed here. We theoretically investigate the formation of the high-order fractional alignment echo in OCS molecule and systematically study the dependence of echo intensity on the intensities and time delay of the two excitation pulses. It is well known that the optical properties of multi-level atomic and molecular system can be controlled and manipulated efficiently using quantum coherence and interference, which has led to many new effects in quantum optics for e.g. R. Inaba, K. Tominaga, M. Tasumi, K. A. Nelson, and K. Yoshihara, “Observation of homogeneous vibrational dephasing in benzonitrile by ultrafast Raman echoes,” Chem. The observable $\langle cos(2n\theta )\rangle (t)$ is a summation of terms $|J\rangle \langle J|$ (i.e., the dots along the diagonal of the RDMs in Fig. [CrossRef], 41. H. Yuan, L. He, S. M.

Coherent optical spectroscopy of a single quantum dot using photon counting statistics. When P$_2$ is applied, the state $|J-2\rangle$ can be excited to $|J+2\rangle$ by two Raman excitations. The transition probabilities of the related transition pathways exhibit sin$^{3}$- and sin$^{4}$-dependence on I$_2$, respectively, which are also consistent with the TDSE simulations in Fig. Lett.

The research activities of this division over the past year are summarized as follows: Extracting Work from a Single Heat Bath via Vanishing Quantum Coherence. In summary, we have investigated the formation of the HFAEs in OCS molecule and studied the dependence of HFAE intensity on the intensities and delay between the two excitation pulses. 2(a), the intensity of the full alignment echo oscillates as $I_2$ increases. 44 Citations; 4.6k Downloads; Log in to check access.

In fact, multiple interactions with P$_1$, and a single interaction with P$_2$ can also contribute to the alignment echoes. [Crossref], J. Yan, W. Xie, M. Li, K. Liu, S. Luo, C. Cao, K. Guo, W.

In this work, we perform the simulations with OCS molecule, since it has a long revival period (T$_{rev}\sim 82 ps$) without quarter revivals, which can provide a broad time window for the study of the echo phenomena.
