Maximally-fast coarsening algorithms
Mowei Cheng, Andrew Rutenberg
We present maximally-fast numerical algorithms for conserved coarsening systems that are stable and accurate with a growing natural time-step . For non-conserved sy…
Scaling state of dry two-dimensional froths: universal angle deviations and structure
Andrew D. Rutenberg, Micah B. McCurdy
We characterize the late-time scaling state of dry, coarsening, two-dimensional froths using a detailed, force-based vertex model. We find that the slow evolution of bubbles leads…
Space-time Averages of Classical Physical Fields
Roustam Zalaletdinov
A review on the main results concerning the algebraic and differential properties of the averaging and coordination operators and the properties of the space-time averages of macro…
Gravitational entropy in cosmological models
Nicos Pelavas, Alan Coley
We discuss whether an appropriately defined dimensionless scalar function might be an acceptable candidate for the gravitational entropy, by explicitly considering Szekeres and Bia…
Alternative Perspective on Quantum Tunneling and Instantons
F. Paradis, H. Kroger, G. Melkonyan +1
We present a new way to compute and interpret quantum tunneling in a 1-D double-well potential. For large transition time we show that the quantum action functional gives an analyt…
Coherent rotations of a single spin-based qubit in a single quantum dot at fixed Zeeman energy
Jordan Kyriakidis, Stephen J. Penney
Coherent rotations of single spin-based qubits may be accomplished electrically at fixed Zeeman energy with a qubit defined solely within a single electrostatically-defined quantum…
