Relaxation and Thermalization in Many-Body Systems Coupled to Different Bosonic Degrees of Freedom

07 Apr2016

Speaker: J. Bonča, University of Ljubljana

Time: April 7, 2016, 2:00 - 3:00

Location: Hennings 318

In the first part I will briefly overview a fundamental study of the relaxation dynamics of a single hole in the two dimensional t-J model initially excited by a strong quench. Taking fully into account quantum effects we may follow the time-evolution of the system from a highly excited state until it reaches a steady state. Relaxation occurs on...

Tunable Electronic and Magnetic Properties of Rare-Earth Nickelate Heterostructures

05 Apr2016

Speaker: Matthias Hepting, MPI-FKF Stuttgart

Time: April 5, 2016, 1:30 - 2:30

Location: AMPEL 311

The rich phase diagram of transition metal oxides (TMO) such as rare-earth nickelates RNiO3 (R = rare-earth) results from the interplay between charge, orbital, spin, and lattice degrees of freedom. In the talk it will be described how this interplay can be manipulated in epitaxial RNiO3 heterostructures and how new phases can be designed, distinct from the ones existing...

Hacking the Superconducting Nanowire: Detecting Single Photons, Resurrecting the Cryotron, and Pushing Current Around Corners

31 Mar2016

Speaker: Karl Berggren, MIT

Time: March 31, 2016, 2:00 - 3:00

Location: Hennings 318

Superconducting nanowires have long been of interest for their unusual electrothermal behavior, and the exhibition of quantum phase slips–twists in the electron wavefunction that can occur spontaneously in the right environment. However, they have also demonstrated themselves recently to be of key importance to the field of photodetection, with important applications in communications and metrology. With these nanowires, individual...

Entropy-Stabilized Oxides

24 Mar2016

Speaker: Jon-Paul Maria, North Carolina State University

Time: March 24, 2016, 2:00 - 3:00

Location: Hennings 318

The hunt for, and discovery of, new phases of matter is among the most exciting activities Materials Research. The excitement originates from the possibility of active property engineering and advanced technology opportunities that serve societal needs. As a community, we have been looking for a long time, and given the finite number of practical elements and their stable combinations,...

Anomalous Dimensions and Unparticles in the Cuprate Superconductors

10 Mar2016

Speaker: Philip Phillips

Time: March 10, 2016, 2:00 - 3:00

Location: Hennings 318

High-temperature superconductivity in the cuprates remains an unsolved problem because no knock-down experiment has revealed unambiguously the nature of the charge carriers in the normal state. I will show here that what is strange about the normal state is that the current for the underlying charge carriers possess an anomalous dimension. To show this, I will focus on the...

Green Function for the Nonlinear Luttinger Liquid from Nonlinear Steepest Descent

08 Mar2016

Speaker: Tom Price (Cambridge University, UK)

Time: March 8, 2016, 2:00 - 3:00

Location: Hennings 318

We discuss the time dependent Green function of the nonlinear Luttinger liquid, using the Fractional Quantum Hall edge as an example. The Green function can be written as a Fredholm determinant, whose long time asymptotics we find by solving an associated Riemann–Hilbert problem using the method of nonlinear steepest descent. The results agree exactly with the mobile impurity model,...

In-Situ Investigation of Growth and Superconductivity of Single-Layer FeSe Films on SrTiO3

07 Mar2016

Speaker: Jianfeng Ge (Shanghai Jiao Tong University)

Time: March 7, 2016, 2:00 - 3:00

Location: AMPEL 311

Superconductivity with critical temperature above boiling point of nitrogen or even room temperature has been a pursuing goal of researchers ever since its discovery, because of its potential application in future electronic devices. Interface effects were found to induce superconductivity between insulating oxides, as well to enhance critical temperature of superconducting films, which matches the technology of device manufacturing...

Atomic-Resolution Studies of Materials by Abberation-Corrected Scanning Transmission Electron Microscopy

03 Mar2016

Speaker: Ondrej L. Krivanek, Arizona State University

Time: March 3, 2016, 2:00 - 3:00

Location: Hennings 318

Aberration-corrected scanning transmission electron microscopes (STEMs) are now able to form electron probes as small as 0.5 Å in diameter, and they can image and spectroscopically analyze single atoms in-situ. Nion Co., has pioneered these advances, by developing the first aberration corrector that improved spatial resolution of an electron microscope to better than 1 Å, and later on by...

Photoemission Electron Microscopy for Ultrafast Nano-Optics: Femtoseconds to Attoseconds

26 Feb2016

Speaker: Erik Marsell, Lund University

Time: February 26, 2016 2:00 - 3:00

Location: AMPEL 311

Nano-optics, the use of nanostructured surfaces for the concentration, manipulation, and application of light on a sub-wavelength scale, is a maturing technology capable of connecting the worlds of photonics and electronics. This opens up possibilities for devices combining the small size currently only found in electronics with the high operating speed offered by photonics. However, the simultaneous small and...

Atomic Dynamics via meV-Resolution X-Ray Scattering: New Results on High-Temperature Superconductors

25 Feb2016

Speaker: Alfred Baron, Materials Dynamics Laboratory, RIKEN SPring-8 Center

Time: February 25, 2016, 2:00 - 3:00

Location: AMPEL 311

High-resolution inelastic x-ray scattering (IXS) measures atomic motions at THz frequencies over angstrom-scale correlation lengths. While the required instrumentation is difficult to set up, dedicated facilities make the method available to the broader scientific community, and potentially of interest for anyone studying lattice dynamics, electron-phonon coupling, superconductivity, ferro-electricity/multi-ferroicity, phase transformations, magneto-elastic coupling, elasticity, or the dynamics of liquids or...
