The GCN Seminar - Photoluminescence

This seminar series is organized by the three nanoscience hubs located in the Copenhagen-Lund area. The aim is to to increase awareness about our mutual capabilities and to inspire collaborations. Below, please find the talk abstracts and short bio of the speakers on the Photoluminescence topic. Within a radius of just 25 km, the Copenhagen-Lund region features three strong hubs for nanoscience, w

We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabilized by strong repulsive interactions between the two spin components without the need for an external periodic potential. We independently characterize the spin configuration of the chains by measuring the spin orientatio

Coda wave interferometry (CWI) has been demonstrated to be a very sensitive tool for detecting early signs of damage in concrete. The choice of frequency in SHM applications, utilizing coda waves, is not straight-forward, as there is a trade-off in sensitivity and possible propagation distances. This study aims to provide some steps in establishing recommendations as to choice of frequency, when d

PhD project on information as fuel

Fundamental relations between information and energy – Building electronic devices that use information as fuel Scanning electron micrograph of a quantum dot structure where the movement of single electrons can be controlled and detected. The movement of a single electron in the structure yields the elemental amount of energy of kT ln(2) related to a single bit of information at temperature T. Fig

The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers. However, a great deal of interest is due to the rich physics that emerges from the study of spin

Timber structures are increasingly growing in importance and utilization. A contributing factor to this trend is the introduction of cross-laminated timber (CLT). CLT is an engineered wood product comprising layers of wood made up of multiple boards, alternately referred to as "lamellae". Each layer is positioned perpendicular to the next and bonded together with adhesives. CLT is mostly

NMR spin relaxation in the rotating frame (R-1 rho) is a unique method for atomic-resolution characterization of conformational ( chemical) exchange processes occurring on the microsecond time scale. Here, we use amide H-1 off-resonance R-1 rho relaxation experiments to determine exchange parameters for processes that are significantly faster than those that can be probed using N-15 or C-13 relaxa

We report low-temperature magnetotransport studies of individual InAs nanowires grown by molecule beam epitaxy. At low magnetic fields, the magnetoconductance characteristics exhibit a crossover between weak antilocalization and weak localization by changing either the gate voltage or the temperature. The observed crossover behavior can be well described in terms of relative scales of the transpor

Most of the decisive molecular events in biology take place at the protein-water interface. The dynamical properties of the hydration layer are therefore of fundamental importance. To characterize the dynamical heterogeneity and rotational activation energy in the hydration layer, we measured the 17O spin relaxation rate in dilute solutions of three proteins in a wide temperature range extending d

A paired cranked Nilsson-Strutinsky-Bogoliubov (CNSB) model is presented, which employs the same method to calculate the liquid-drop energy and moment of inertia as the unpaired cranked Nilsson-Strutinsky (CNS) model. In the CNSB model, the energy minimization is carried out in the mesh of pairing gaps Delta and Fermi levels lambda as well as deformation parameters. The high spin states in Lu-161

X-ray absorption spectroscopy is a powerful probe of molecular structure, but it has previously been too slow to track the earliest dynamics after photoexcitation. We investigated the ultrafast formation of the lowest quintet state of aqueous iron(II) tris(bipyridine) upon excitation of the singlet metal-to-ligand-charge-transfer ( 1

PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this

We have used femtosecond resolution UV-visible and Kβ x-ray emission spectroscopy to characterize the electronic excited state dynamics of [Fe(bpy)2(CN)2], where bpy=2,20-bipyridine, initiated by metal-to-ligand charge transfer (MLCT) excitation. The excited-state absorption in the transient UV-visible spectra, associated with the 2,20-bipyridine radical anion, provides a robust marker for the MLC

High-spin states in 154Dy have been studied using the TESSA2 γ-rays spectrometer following the 110Pd(48Ca,4n)154Dy reaction at a beam energy of 210 MeV. States up to 44+ and 37- have been observed. Below spin 30 the data display regular rotational behaviour which can be interpreted in terms of the cranked shell model. Above spin 30, sequences of levels connected by stretched E2 transitions, which

A comparison between the observed spectrum of 155Dy and calculations suggests that the yrast states in the I+30-40 region are built from bands whose deformation smoothly changes towards oblate shape (γ=60°) with band terminations in the I=45-50 region. The presence of other bands which show no terminating features is also naturally understood within the same theoretical framework.

Quark spin effects in e+e- annihilation to pseudoscalar and vector mesons are implemented for the first time in the pythia Monte Carlo event generator. The spin-dependent fragmentation of the string stretched between the produced quark-antiquark pair with correlated spin states is described by the string+P30 model implemented in the string fragmentation routine of pythia by using the StringSpinner

Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
