Local-time formula for dissipation in solid ionic electrolytes

Autor: Rodin, A., Olsen, B. A., Ustyuzhanin, A., Maevskiy, A., Noori, K.

When ions move through solids, they interact with the solid's constituent atoms and cause them to vibrate around their equilibrium points. This vibration, in turn, modifies the potential landscape through which the mobile ions travel. Because the pre

Microscopic theory of thermalization in 1D with nonlinear bath coupling

Autor: Rodin, A., Olsen, B. A., Choi, M., Tan, A.

Using a non-perturbative classical model, we numerically investigate the dynamics of mobile particles interacting with an infinite chain of harmonic oscillators, an abstraction of ionic conduction through solid-state materials. We show that coupling

Observation of quantum-limited spin transport in strongly interacting two-dimensional Fermi gases

Autor: Luciuk, C., Smale, S., Böttcher, F., Sharum, H., Olsen, B. A., Trotzky, S., Enss, T., Thywissen, J. H.

Publikováno v: Phys. Rev. Lett. 118, 130405 (2017)

We measure the transport properties of two-dimensional ultracold Fermi gases during transverse demagnetization in a magnetic field gradient. Using a phase-coherent spin-echo sequence, we are able to distinguish bare spin diffusion from the Leggett-Ri

Spin-velocity correlations of optically pumped atoms

Autor: Marsland III, R., McGuyer, B. H., Olsen, B. A., Happer, W.

Publikováno v: Phys. Rev. A 86, 023404 (2012)

We present efficient theoretical tools for describing the optical pumping of atoms by light propagating at arbitrary directions with respect to an external magnetic field, at buffer-gas pressures that are small enough for velocity-selective optical p

Cusp Kernels for Velocity-Changing Collisions

Autor: McGuyer, B. H., Marsland III, R., Olsen, B. A., Happer, W.

Publikováno v: Phys. Rev. Lett. 108, 183202 (2012)

We introduce an analytical kernel, the "cusp" kernel, to model the effects of velocity-changing collisions on optically pumped atoms in low-pressure buffer gases. Like the widely used Keilson-Storer kernel [J. Keilson and J. E. Storer, Q. Appl. Math.
