King plots have long been used to extract information about relative nuclear charge radii from observed transition frequencies for three or more isotopes of the same element. They have also recently been proposed as a method to search for anomalies that may indicate new physics beyond the standard model [1]. However, an underlying assumption is that the normal and specific isotope shifts...
Helically sculptured thin films have been an interesting topic in applied optics; mainly because of their controlled optical properties such as optical activity and they can be fabricated by almost any material. These thin films were made by glancing angle deposition (GLAD) which allows us to control the orientation of the substrate during the deposition allowing the helical nanostructure. If...
Beta decay of the $^6$He halo nucleus to form $^6$Li$^+$ may provide evidence for new physics beyond the standard model [1]. After the decay occurs, the two atomic electrons become redistributed over all possible states of the daughter $^6$Li nucleus, including single- and double-electron emission (shake-off). The present study focuses on the probability for double electron emission to form...
We describe the theory of black hole analogues in atomic Bose-Einstein condensates (BECs). An event horizon can occur in such systems if there is a region where the flow speed of the gas exceeds the speed of sound. Such sonic black holes create negative frequency modes that have a positive norm, resulting in negative energies within the Hamiltonian of elementary excitations. An analogue of...
Engineering light absorption in GeSn structures is crucial to enhance their basic device performance for a variety of applications such as MIR photodetectors and solar cells. Surface texturing to reduce the reflectivity is a key strategy to tune the optical properties. Since Group IV semiconductors typically have large refractive indices compared to air (between 3.4 and 4.2), planar...
