Klein's technique.
Greenberg J. Greenberg J. Int J Psychoanal. 2018 Aug;99(4):979-989. doi: 10.1080/00207578.2018.1490986. Int J Psychoanal. 2018. PMID: 33951839
Reading these heretofore unpublished works by Melanie Klein is certain to surprise their readers, regardless of their previous familiarity with her work. Bound though she was to an earlier vision of the psychoanalytic situation and to an epistemology that today may strike …

Kaluza-Klein Spectrometry for Supergravity.
Malek E, Samtleben H. Malek E, et al. Phys Rev Lett. 2020 Mar 13;124(10):101601. doi: 10.1103/PhysRevLett.124.101601. Phys Rev Lett. 2020. PMID: 32216423
We show that they provide a highly efficient tool to compute the Kaluza-Klein mass spectra associated with compactifications around various background geometries relevant for string theory and holographic applications. ...As an illustration, we determine the masses of some …

Angular-Dependent Klein Tunneling in Photonic Graphene.
Zhang Z, Feng Y, Li F, Koniakhin S, Li C, Liu F, Zhang Y, Xiao M, Malpuech G, Solnyshkov D. Zhang Z, et al. Phys Rev Lett. 2022 Dec 2;129(23):233901. doi: 10.1103/PhysRevLett.129.233901. Phys Rev Lett. 2022. PMID: 36563206
The Klein paradox consists in the perfect tunneling of relativistic particles through high potential barriers. ...We report the first experimental observation of perfect Klein transmission in a 2D photonic system (photonic graphene) at normal incidence and measure t …

Klein Tunneling in beta(12) Borophene.
Lai J, Wang L, Li F, Zhang H, Zhang Q. Lai J, et al. Nanomaterials (Basel). 2024 May 1;14(9):790. doi: 10.3390/nano14090790. Nanomaterials (Basel). 2024. PMID: 38727384 Free PMC article.
Motivated by the recent observation of Klein tunneling in 8-Pmmn borophene, we delve into the phenomenon in beta(12) borophene by employing tight-binding approximation theory to establish a theoretical mode. ...This is analogous to the "super", all-angle transmission repor …

Anomalous Klein tunneling in two-dimensional black phosphorus heterojunctions.
Chen SG, Zhang BY, Yang ZW, Gong WJ. Chen SG, et al. Phys Chem Chem Phys. 2023 Sep 13;25(35):23836-23846. doi: 10.1039/d3cp03161f. Phys Chem Chem Phys. 2023. PMID: 37641860
More interestingly, when different band gaps are taken into account on two sides of this junction, the maximum transmission appears away from the center of the valley, leading to the occurrence of anomalous Klein tunneling. Such a result tends to be independent of the widt …

Biallelic variants in PAX3 cause Klein syndrome.
Salah S, Meiner V, Abumayaleh A, Asafra A, Al-Sharif T, Al-Fallah O, Hasasneh B, Zlotogora J. Salah S, et al. Clin Genet. 2022 Sep;102(3):223-227. doi: 10.1111/cge.14167. Epub 2022 Jun 5. Clin Genet. 2022. PMID: 35607853
Heterozygous or homozygous variants in the PAX3 gene cause Klein-Waardenburg syndrome. Here we report on a new severely affected child, with a homozygous PAX3 variant (c.251C>T; p.Ser84Phe), review the features of the syndrome, and propose a new classification. ...Patie …

Two Phases in the Intervention of Melanie Klein.
Jofré L. Jofré L. Psychoanal Q. 2023;92(2):289-308. doi: 10.1080/00332828.2023.2237500. Epub 2023 Aug 24. Psychoanal Q. 2023. PMID: 37616558
In 1930, Melanie Klein published an article presenting the case of Dick. Within the framework of the psychoanalytic technique adapted to the clinical treatment of autism, this article contributes elements to a question posed by many psychoanalysts: why did Klein's i …

Direct observation of Klein tunneling in phononic crystals.
Jiang X, Shi C, Li Z, Wang S, Wang Y, Yang S, Louie SG, Zhang X. Jiang X, et al. Science. 2020 Dec 18;370(6523):1447-1450. doi: 10.1126/science.abe2011. Science. 2020. PMID: 33335060
We created a phononic heterojunction by sandwiching two types of artificial phononic crystals with different Dirac point energies. The direct observation of Klein tunneling as shown by the key feature of unity transmission is demonstrated. Our experiment reveals that Kl …
