Quantum Interchange Walk as a Unifying Approach

Creator:: Dimcovic, Zlatko and Kovchegov, Yevgeniy
Abstract:: We construct a quantum interchange walk, related to classical walks with memory. This gives us a coinless discrete walk, while the origin in classical walks with memory offers the promise of use of existing tools from classical memoried walks. This approach readily reproduces all standard approaches. We briefly discuss its...

Look Ma, no beads: Analyzing traction force characteristics of migratory adenocarcinoma in heterogeneous type-1 collagen through bead-free confocal microscopy

Creator:: Groves, Nicholas Scott
Abstract:: Current methods in traction force analysis rely on a homogeneous extra-cellular matrix and embedded microbeads to track deformations. The efficacy of these methods decreases when the matrix is not homogeneous. In heterogeneous matrices, beads often aggregate in regions of higher matrix density and float in regions where matrix substrate is...

Scaling of thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] resistivity-current isotherms at low fields: Implications for vortex phase transitions and universality

Creator:: Roberts, J. M., Brown, Brandon, Tate, Janet, Xi, X. X., and Mao, S. N.
Abstract:: We have investigated a second-order phase transition of the vortex lattice in thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] from 1 mT to 1 T applied magnetic fields. The dc resistivity-current density data for each field exhibit critical scaling consistent with a second-order vortex-liquid to vortex-solid phase transition. The high-field data support the vortex-glass...

Organic semiconductor composites: influence of additives on the transient photocurrent

Creator:: Day, Jonathan, Platt, Andrew D., Ostroverkhova, Oksana, Subramanian, Sankar, and Anthony, John E.
Abstract:: We report on the effect of various guest molecules added to a functionalized anthradithiophene (ADT) host on photoexcited charge carrier dynamics in solution-deposited thin films, from ~100 ps to >100 μs after photoexcitation with 100 fs laser pulses. An addition of 2 and 5 wt % of C60 to a...

Midinfrared semiconductor optical metamaterials

Creator:: Hoffman, Anthony J., Sridhar, Aishwarya, Braun, Phillip X., Alekseyev, Leonid, Howard, Scott S., Franz, Kale J., Cheng, Liwei, Choa, Fow-Sen, Sivco, Deborah L, Podolskiy, Viktor A., Narimanov, Evgenii E., and Gmachl, Claire
Abstract:: We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two types of metamaterials, layered highly doped/undoped heterostructures and quantum well superlattices that are highly anisotropic. Contrary to other...

Exciton dynamics in atomically thin MoS2: Interexcitonic interaction and broadening kinetics

Creator:: Sim, Sangwan, Park, Jusang, Song, Jeong-Gyu, In, Chihun, Lee, Yun-Shik, Kim, Hyungjun, and Choi, Hyunyong
Abstract:: We report ultrafast pump-probe spectroscopy examining exciton dynamics in atomically thin MoS2. Spectrally and temporally resolved measurements are performed to investigate the interaction dynamics of two important direct-gap excitons (A and B) and their associated broadening kinetics. The two excitons show strongly correlated interexcitonic dynamic, in which the transient blue-shifted...

Temperature dependence of exciton and charge carrier dynamics in organic thin films

Creator:: Platt, A. D., Kendrick, M. J., Loth, M., Anthony, J. E., and Ostroverkhova, O.
Abstract:: We report on physical mechanisms behind the temperature-dependent optical absorption, photoluminescence (PL), and photoconductivity in spin-coated films of a functionalized anthradithiophene (ADT) derivative, ADT-triethylsilylethynyl (TES)-F, and its composites with C₆₀ and another ADT derivative, ADT-TIPS-CN. Measurements of absorption and PL spectra, PL lifetimes, and transient photocurrent were performed at temperatures...

Amorphous TiO₂ : A Thin Film Synthesis Route to Stabilization of Metastable TiO₂ Brookite

Creator:: Haggerty, James E. S.
Abstract:: Structure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO₂, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO₂, a promising photocatalyst, has been difficult in both powder and thin-film forms due...
