Quantum Phases and Correlations Drive the Dynamics of Macroscopic Quantum Tunneling Escape in Quantum Simulators
Diego A. Alcala, Marie A. McLain, Lincoln D. Carr
Quantum tunneling remains unexplored in many regimes of many-body quantum physics, including the effect of quantum phase transitions on tunneling dynamics. In general, the quantum…
Physical realization of complex dynamical pattern formation in magnetic active feedback rings
Justin Q. Anderson, P. A. Praveen Janantha, Diego A. Alcala +2
We report the clean experimental realization of cubic-quintic complex Ginzburg-Landau physics in a single driven, damped system. Four numerically predicted categories of complex dy…
Macroscopic quantum escape of Bose-Einstein condensates: Analysis of experimentally realizable quasi-one-dimensional traps
Diego A. Alcala, Gregor Urban, Matthias Weidemüller +1
The variational-JWKB method is used to determine experimentally accessible macroscopic quantum tunneling regimes of quasi-bound Bose-Einstein condensates in two quasi one-dimension…
For high-precision bosonic Josephson junctions, many-body effects matter
Marie A. McLain, Diego A. Alcala, Lincoln D. Carr
Typical treatments of superconducting or superfluid Josephson junctions rely on mean-field or two-mode models; we explore many-body dynamics of an isolated, ultracold, Bose-gas lon…
Macroscopic Quantum Tunneling Escape of Bose-Einstein Condensates
Xinxin Zhao, Diego A. Alcala, Marie A. McLain +5
Recent experiments on macroscopic quantum tunneling reveal a non-exponential decay of the number of atoms trapped in a quasibound state behind a potential barrier. Through both exp…
Entangled Dynamics in Macroscopic Quantum Tunneling of Bose-Einstein Condensates
Diego A. Alcala, Joseph A. Glick, Lincoln D. Carr
Tunneling of a quasibound state is a non-smooth process in the entangled many-body case. Using time-evolving block decimation, we show that repulsive (attractive) interactions spee…
Weakly Explosive Percolation in Directed Networks
Shane Squires, Katherine Sytwu, Diego Alcala +3
Percolation, the formation of a macroscopic connected component, is a key feature in the description of complex networks. The dynamical properties of a variety of systems can be un…
