| Switching of control mechanisms during the rapid solidification of alloys |
Switching of control mechanisms during the rapid solidification of alloys
Abstract
The formation of complex solidification patterns is an intrinsic non-equilibrium phenomenon. It is the interplay between capillary and kinetic effects at the solidification front (… Show more Speaker: Dr. Yijia Gu |

| Radiative cooling: harness sustainable coldness from the universe for passive cooling on the Earth |
Abstract
Radiative cooling is a passive cooling technique featured with zero-energy consumption by emitting terrestrial heat to the universe in form of blackbody thermal radiation. Nocturnal radiative cooling is an ordinary phenomenon of radiative cooling effect… Show more Speaker: Professor Yao Zhai |

| High-spin quasiparticles in topological semimetal YPtBi |
Quasiparticles with total angular momentum greater than j=1/2 can emerge in a solid state with strong spin-orbit interaction. While the existence of such high-spin quasiparticles has been known for decades, their implication has been largely overlooked. The… Show more Speaker: Prof. Hyunsoo Kim, Department of Physics, Missouri S&T |
|
| Synthesis, Magnetic Behavior and Neutron Diffraction of Triangular Magnetic Materials |
Triangular magnetic structures have gained considerable interest due to their rich magnetic behavior and structural simplicity. These structures contain the motif of a triangle as the main structural feature, leading to geometric frustration and implicitly to… Show more Speaker: Prof. Duminda Sanjeewa, MURR |
|
| Nanopore Unzip-Sequencing – exploration in biomolecular interactome and next generation information storage |
DNA is a new generation material for molecular data storage, with a potential storage capacity several orders of magnitude greater than current methods. Data stored in DNA can be encoded (written) and decoded (read) using sequencing technologies. Advantages of DNA… Show more Speaker: Andrew Gu, MU Bioengineering |
|
| A soft X-ray coherent view of electronic properties in correlated systems, via Resonant X-ray Scattering |
Claudio Mazzoli will present some opportunities of scientific investigation by micro-spectro-scattering in the soft X-ray regime of Resonant X-ray Scattering, as implemented and developed at CSX (the Coherent Soft X-ray scattering beamline of NSLS-II, BNL). The… Show more Speaker: Claudio Mazzoli, BNL |
|
| Spontaneous cluster formation in stoichiometric quantum critical systems |
Metallic systems with magnetic ions embedded which have been prepared to undergo a second-order phase transition at zero Kelvin, namely the quantum critical systems, historically appear to fall into two distinct categories: (chemically) heavily-doped systems in which… Show more Speaker: Alex Bretana |
|
| Using machine-learning methods to model RNA-ligand interactions |
Convolutional neural network (CNN) and graph convolutional network (GCN) has gained huge success in various tasks, from image classification, video processing to speech recognition and natural language understanding. The success stems from both the well-designed… Show more Speaker: Yuanzhe Zhou, MU Physics |

|
| Observation of the Layer Hall Effect in Topological Axion Antiferromagnet MnBi2Te4 |
While ferromagnets have been known and exploited for millennia, antiferromagnets were only discovered in the 1930s. The elusive nature indicates antiferromagnets’ unique properties: At large scale, due to the absence of global magnetization, antiferromagnets may… Show more Speaker: Prof. SuYang Xu, Department of Chemistry, Harvard University |
|
| Nanoscale confinement towards a one-dimensional superfluid |
In one spatial dimension, enhanced thermal and quantum fluctuations should preclude the existence of any long range ordered superfluid phase of matter. Instead, the quantum liquid should be described at low energies by an emergent hydrodynamic framework known… Show more Speaker: Adrian Del Maestro, University of Tennessee |
|
| Electron and ion dynamics in materials due to particle radiation and optical excitation |
Materials manipulation via ion or laser beams can achieve precisely tuned atomic geometries that are necessary, e.g. to engineer interactions between defects in quantum materials and for fabricating novel electronic devices with nanoscale dimensions. In addition,… Show more Speaker: Andre Schleife, UIUC |
|
| Control of Magnetization in Topological Insulator/Magnetic Insulator Heterostructures |
Spintronics-based technology, which uses spins to represent and propagate information, holds promise to realize devices that surpass the current CMOS transistor technology in power, density and speed. For example, magnetic random-access memory (MRAM) based on… Show more Speaker: Prof. Peng Li, Auburn University |

| Hunting for topological phases amidst Hofstadter butterflies and disordered landscapes |
In this talk, I will discuss rich topological behavior in two related models – the Majorana wire and a Su-Schrieffer-Heeger ladder- in the presence of potential energy landscapes. An introduction of the two models and of techniques that directly provide information… Show more Speaker: Smitha Vishveshwara, UIUC |
|
| Fundamentals of Amorphous Oxide Semiconductors |
Amorphous oxide semiconductors (AOS)—ternary or quaternary oxides of post-transition metals—have attracted a lot of attention due to high carrier mobility which is an order of magnitude larger than that of amorphous silicon (a-Si:H). Unlike Si-based semiconductors,… Show more Speaker: Julia Medvedeva, University of Missouri S&T |
|
| Combined Magnetic Tweezers-TIRF microscopy for studying DNA-protein interactions |
Magnetic tweezers allow the user to apply force and torque to magnetic beads attached to single DNA molecules, and to observe the resulting changes in DNA extension. This technique, however, is limited to measuring a single degree of freedom: the distance between the… Show more Speaker: Maria Mills, MU Physics |

| Manifestations of band geometry in linear and nonlinear transport |
I will describe how the geometry of the band structure of metals manifests itself in their optical and transport properties.
