Analytically Solvable Problems in Quantum Mechanics and SWKB Quantization Condition

Yuta Nasuda

Tokyo University of Science

Abstract:

The Schrödinger-type equation appears not only in quantum mechanics but also in every corner of physics. It has long been studied what the basic feature of solvable potentials is, and how one solves the equation with those potentials analytically. Today we know infinitely many solvable potentials, but we still have no whole notion of the solvability of the Schrödinger equation. In this seminar, we first review several essential concepts in the solvability of the Schrödinger equation: factorization of Hamiltonian, shape invariance, and so on. Then we introduce the SWKB quantization condition, which is relevant to the solvability of the Schrödinger equation. We apply the condition to several solvable problems and show how they are closely connected.

Optical spectroscopy: from a luminescent molecule to working OLED devices

MSc Larissa Gomes França

Department of Physics , Durham University – UK

Abstract:

Organic light-emitting diodes (OLEDs) have attracted tremendous interest from the luminescent display industry over the last years. Nowadays, this technology is already a part of peoples’ lives as being used in everyday items such as in mobile phones and televisions. Using organic semiconductors instead of the more traditional inorganic (i.e. GaN, InGaN, GaAs, etc.) introduces many technological advantages. Among them are flexibility, very low thickness of final luminescent displays as well as possibility to produce transparent displays and luminaries. In an OLED device, applied voltage bias induces injection of electrons and holes through the device cathode and anode, respectively. The charge carriers are transported through the device and migrate to the emissive layer where they recombine, generating light. Spin statistics based on the spin states of holes and electrons undergoing recombination leads to a 1:3 ratio between multiplicities of thus produced excited states: singlets and triplets. Considering that often triplet states do not contribute to the luminescent output of an OLED the efficiency of these devices becomes limited to 25% of what it could be. Mechanisms that enable turning non-emissive triplet states into luminescent singlets will be discussed in this talk. Key parameters to maximise efficiency of these mechanisms allowing 100% utilisation of all electron-hole recombination will also be covered.

Insights into Publishing at the Nature Portfolio, Open Access, and Demystifying the Editorial Process

Dr. Gustavo Tontini

Associate Editor, Nature Communications-Springer Nature

Abstract:

Dr Gustavo Tontini is an Editor at Nature Communications, an open access, multidisciplinary journal dedicated to publishing high-quality impactful research in all areas of the biological, health, physical, chemical, and Earth sciences. In this talk, we’re going to discuss about submitting research to journals at the Nature Portfolio, how editorial criteria are established, and many aspects of the editorial process in handling manuscripts, assessing research, and guiding manuscripts through peer-review.

Date: October 21, 2022 – (friday) – Time: 10:15 a.m.

Gemini NIFS survey of feeding and feedback processes in nearby active galaxies: stellar populations

Prof. Rogério Riffel

Departamento de Astronomia, UFRGS

Abstract:

Active Galactic Nuclei (AGN) characterize a critical phase in galaxy evolution in which its nuclear supermassive black hole (SMBH) is being fed due to gas accretion onto the nuclear region. The AGN feeding and feedback processes are believed to couple the growth of the SMBHs and their host galaxies and are claimed to be responsible for the correlation between the mass of the SMBH and that of the galaxy bulge. The co-evolution scenario and the gas feeding in the inner kiloparsec of galaxies when they are in the active phase imply that the galaxy bulge grows in consonance with the SMBH. Over the last few years, our team has undertaken a major observational effort to understand this co-evolution by recovering the spatially resolved star formation history and studying the stellar kinematics of the inner few tens parsecs of galaxies. To this purpose we are applying an updated version of the STARLIGHT code to Gemini Near-infrared Integral Field Spectrograph (NIFS) data-cubes of nearby Seyfert galaxies. I will discuss these results in this talk.simulations . Unambiguous evidence that ad hoc molecular design enables the electron charge carriers to be freed from both internal and external disorder to ultimately reach band-like transport is provided.
