Simulating Cosmological Evolution by Quantum Quench of an Atomic BEC
Ke Wang, Han Fu, K. Levin
In cosmological evolution, it is the homogeneous scalar field (inflaton) that drives the universe to expand isotropically and to generate standard model particles. However, to simu…
Dynamical preparation of an atomic condensate in a Hofstadter band
Han Fu, Andreas Glatz, F. Setiawan +4
The creation of a Hamiltonian in the quantum regime which has non-trivial topological features is a central goal of the cold-atom community, enabling widespread exploration of nove…
Jet Sub-structure in Fireworks Emission from Non-uniform and Rotating Bose-Einstein Condensates
Han Fu, Zhendong Zhang, Kai-Xuan Yao +5
We show that jet emission from a Bose condensate with periodically driven interactions, a.k.a. "Bose fireworks", contains essential information on the condensate wavefunction, whic…
Band-Gap-Dependent Electronic Compressibility of Carbon Nanotubes in the Wigner Crystal Regime
Neda Lotfizadeh, Daniel R. McCulley, Mitchell J. Senger +4
Electronic compressibility, the second derivative of ground state energy with respect to total electron number, is a measurable quantity that reveals the interaction strength of a…
Density waves and jet emission asymmetry in Bose Fireworks
Han Fu, Lei Feng, Brandon M. Anderson +5
A Bose condensate subject to a periodic modulation of the two-body interactions was recently observed to emit matter-wave jets resembling "fireworks" [Nature 551, 356(2017)]. In th…
Anomalous Thermodynamic Properties of Electron Accumulation Layer in SrTiO
Michael Sammon, Han Fu, B. I. Shklovskii
Due to the nonlinear dielectric response within SrTiO (STO), an accumulation layer created by positive charges at the surface of the STO sample () has an electron densit…
