Excitonic Bloch-Siegert shift in CsPbI(3) perovskite quantum dots.
Li Y, Han Y, Liang W, Zhang B, Li Y, Liu Y, Yang Y, Wu K, Zhu J. Li Y, et al. Nat Commun. 2022 Sep 22;13(1):5559. doi: 10.1038/s41467-022-33314-9. Nat Commun. 2022. PMID: 36138041 Free PMC article.
Coherent interaction between matter and light field induces both optical Stark effect and Bloch-Siegert shift. Observing the latter has been historically challenging, because it is weak and is often accompanied by a much stronger Stark shift. Herein, by controlling the lig …

Bloch-Siegert B1+-mapping for human cardiac (31) P-MRS at 7 Tesla.
Clarke WT, Robson MD, Rodgers CT. Clarke WT, et al. Magn Reson Med. 2016 Oct;76(4):1047-58. doi: 10.1002/mrm.26005. Epub 2015 Oct 28. Magn Reson Med. 2016. PMID: 26509652 Free PMC article.
Accurate measurements of B1+ (and hence flip angle) are necessary for quantitative analysis of (31) P-MR spectra. We demonstrate a Bloch-Siegert B1+-mapping method for this purpose. THEORY AND METHODS: We compare acquisition strategies for Bloch-Siegert B1+-mapping …

Selective excitation localized by the Bloch-Siegert shift and a B1+ gradient.
Martin JB, Srinivas SA, Vaughn CE, Sun H, Griswold MA, Grissom WA. Martin JB, et al. Magn Reson Med. 2022 Sep;88(3):1081-1097. doi: 10.1002/mrm.29271. Epub 2022 Apr 25. Magn Reson Med. 2022. PMID: 35468232 Free PMC article.
PURPOSE: To perform B1+ -selective excitation using the Bloch-Siegert shift for spatial localization. THEORY AND METHODS: A B1+ -selective excitation is produced by an radiofrequency (RF) pulse consisting of two summed component pulses: an off-resonant pulse that induces a …

Average-atom model with Siegert states.
Starrett CE, Shaffer NR. Starrett CE, et al. Phys Rev E. 2023 Feb;107(2-2):025204. doi: 10.1103/PhysRevE.107.025204. Phys Rev E. 2023. PMID: 36932529
This is a challenging numerical and algorithmic problem in large part due to the continuum of free states which is relatively expensive and difficult to resolve accurately. Siegert states are an appealing alternative. They form a complete eigenbasis with a purely discrete …

B(1) inhomogeneity-corrected T(1) mapping and quantitative magnetization transfer imaging via simultaneously estimating Bloch-Siegert shift and magnetization transfer effects.
Jang A, Han PK, Ma C, El Fakhri G, Wang N, Samsonov A, Liu F. Jang A, et al. Magn Reson Med. 2023 Nov;90(5):1859-1873. doi: 10.1002/mrm.29778. Epub 2023 Jul 10. Magn Reson Med. 2023. PMID: 37427533 Free PMC article.
THEORY AND METHODS: Bloch-Siegert shift and magnetization transfer is simultaneously induced through the application of off-resonance irradiation in between excitation and acquisition of an RF-spoiled gradient-echo scheme. ...CONCLUSION: A method of estimating Bloch-Sie …
