Refraction in spacetime
M. Jaaskelainen, M. Lombard, U. Zuelicke
Refraction, interference, and diffraction serve as distinguishing features for wave-like phenomena. While they are normally associated only with a purely spatial wave-propagation p…
Cofinitely Hopfian groups, open mappings and knot complements
Martin R. Bridson, Daniel Groves, Jonathan A. Hillman +1
A group is defined to be cofinitely Hopfian if every homomorphism whose image is of finite index is an automorphism. Geometrically significant groups enjoying this prop…
Traveling Dark Solitons in Superfluid Fermi Gases
Renyuan Liao, Joachim Brand
Families of dark solitons exist in superfluid Fermi gases. The energy-velocity dispersion and number of depleted particles completely determines the dynamics of dark solitons on a…
The emergence of the physical world from information processing
B. Whitworth
This paper links the conjecture that the physical world is a virtual reality to the findings of modern physics. What is usually the subject of science fiction is here proposed as a…
Wave Functions of the Proton Ground State in the Presence of a Uniform Background Magnetic Field in Lattice QCD
Dale S. Roberts, Patrick O. Bowman, Waseem Kamleh +1
We calculate the probability distributions of quarks in the ground state of the proton, and how they are affected in the presence of a constant background magnetic field. We focus…
Inelastic scattering of atoms in a double well
E. S. Annibale, O. Fialko, K. Ziegler
We study a mixture of two light spin-1/2 fermionic atoms and two heavy atoms %in a Mott state in a double well potential. Inelastic scattering processes between both atomic species…
