Phonon Dynamics in Spherically-Curved Analog-Gravity Bose-Einstein Condensates
J. Austin Chunn, Ruotong Zhai, Daniel E. Sheehy
We study the low energy phonon dynamics of a Bose-Einstein condensate (BEC) with a density profile that is equivalent, via a coordinate transformation, to phonons traveling in a \l…
Analog Unruh effect of inhomogeneous one-dimensional Dirac fermions
Khristian B. Tallent, Daniel E. Sheehy
We study one-dimensional Dirac fermions in the presence of a spatially-varying Dirac velocity , that can form an approximate lab-based Rindler Hamiltonian describing an obser…
Ferromagnetic Quantum Critical Point in FeGa3 Tuned by Mixed-Valence Fe Dimers
N. Haldolaarachchige, J. Prestigiacomo, W. Adam Phelan +9
The magnetic, transport, and thermal properties of single crystals of the series Fe(Ga1-xGex)3 are reported. Pure FeGa3 is a nonmagnetic semiconductor, that when doped with small c…
