I'm not getting the appeal of mythological beings that are like a 2-in-1 deal e.g. centaur, minotaur, mermaid or griffin and so on.
BUT I find fish with human legs or birds with human arms funny beyond comparison! These combinations are far superior!

Coherent Optical Control of Electron Dynamics in Patterned Graphene Nanoribbons
The field of coherent electronics aims to advance electronic functionalities by utilizing quantum coherence. Here, we demonstrate a viable and versatile methodology for controlling electron dynamics optically in graphene nanoribbons. In particular, we propose to flatten the band structure of armchair graphene nanoribbons via control electrodes, arranged periodically along the extended direction of the nanoribbon. This addresses a key mechanism for dephasing in solids, which derives from the mom…

The Far-Infrared Enhanced Survey Spectrometer (FIRESS) for PRIMA: Science Drivers
We present the science drivers for the Far-Infrared Enhanced Survey Spectrometer (FIRESS), one of two science instrument on the PRobe Infrared Mission for Astrophysics (PRIMA). FIRESS is designed to meet science objectives in the areas of the origins of planetary atmospheres, the co-evolution of galaxies and supermassive black holes, and the buildup of heavy elements in the Universe. In addition to these drivers, FIRESS is envisioned as a versatile far-infrared spectrometer, capable of addressi…

Need for PRIMA to understand the nature and ISM physical conditions of HST-dark galaxies
One of the main open issues in galaxy formation and evolution is the early assembly of the most massive galaxies and their contribution to the stellar mass and star formation rate densities at early epochs. Massive red sources already in place at z > 2 to 3 have been found in deep Spitzer-IRAC and ALMA surveys. They are often called optically and near-IR dark, or HST-dark, being undetected even in the deepest HST frames. The submillimeter (i.e., ALMA) detection of these sources confirms their h…

Valley-dependent topological interface states in biased armchair nanoribbons in gapless graphene
We investigate an electrical bias-controlled, topological kind discontinuity in valley polarization, in a two-segment armchair nanoribbon of gapless graphene, where the discontinuity is created at the interface by applying opposite in-plane, transverse electrical biases to the two segments. In particular, using an efficient tight-binding theoretical formulation, we explicitly obtain energy eigenvalues and probability distributions of discontinuity-induced, interface-confined electron eigenstate…

Radio-frequency charge detection on graphene electron-hole double quantum dots
High-fidelity detection of charge transitions in quantum dots (QDs) is a key ingredient in solid state quantum computation. We demonstrate high-bandwidth radio-frequency charge detection in bilayer graphene quantum dots (QDs) using a capacitively coupled quantum point contact (QPC). The device design suppresses screening effects and enables sensitive QPC-based charge readout. The QPC is arranged to maximize the readout contrast between two neighboring, coupled electron and hole QDs. We apply th…

Nonvolatile Switching of Magnetism via Gate-Induced Sliding in Tetralayer Graphene
Interlayer sliding degrees of freedom often determine the physical properties of two-dimensional (2D) materials. In graphene, for instance, the metastable rhombohedral stacking arrangement hosts correlated and topological electronic phases, which are absent in conventional Bernal stacking. Here, we demonstrate a sliding-induced first-order structural phase transition between Bernal and rhombohedral tetralayer graphene driven by gate voltages. Through transport measurement, we observe bistable s…

Wave Packet Propagation through Graphene with Square and Triangular Patterned Circular Potential Scatterers
In this study, using the Dirac continuum model combined with the split-operator technique, we investigate the propagation dynamics of wave packets in graphene in the presence of circular potential barriers arranged in square and triangular geometries. Our results reveal a non-monotonic dependence of the wave packet transmission on the number of barrier rows along the propagation direction: the transmission initially decreases as rows of barriers are removed, but then increases again when additi…
