Towards perfect quantum insulation
Rafael Hipolito, Paul M. Goldbart
Electric fields, applied to insulators, cause transitions between valence and conduction bands, giving rise to current. Adjustments of the Hamiltonian can perfect the quality of th…
Scale-dependent elasticity as a probe of universal heterogeneity in equilibrium amorphous solids
Boli Zhou, Rafael Hipolito, Paul M. Goldbart
The equilibrium amorphous solid state -- formed, e.g., by adequately randomly crosslinking the constituents of a macromolecular fluid -- is a heterogeneous state characterized by a…
Control of noisy quantum systems: Field theory approach to error mitigation
Rafael Hipolito, Paul M. Goldbart
We consider the quantum-control task of obtaining a target unitary operation via control fields that couple to the quantum system and are chosen to best mitigate errors resulting f…
Self-trapping in an array of coupled 1D Bose gases
Aaron Reinhard, Jean-Félix Riou, Laura A. Zundel +4
We study the transverse expansion of arrays of ultracold Rb atoms weakly confined in tubes created by a 2D optical lattice, and observe that transverse expansion is delayed…
Quantum damping of Fermi-Pasta-Ulam revivals in ultracold Bose gases
Ippei Danshita, Rafael Hipolito, Vadim Oganesyan +1
We propose an experimental scheme for studying the Fermi-Pasta-Ulam (FPU) phenomenon in a quantum mechanical regime using ultracold atoms. Specifically, we suggest and analyze a se…
Breakdown of macroscopic quantum self-trapping in coupled mesoscopic one dimensional Bose gases
Rafael Hipolito, Anatoli Polkovnikov
Two coupled BECs with a large population imbalance exhibit macroscopic quantum self-trapping (MQST) if the ratio of interaction energy to tunneling energy is above a critical value…
Effects of differential mobility on biased diffusion of two species
R. S. Hipolito, R. K. P. Zia, B. Schmittmann
Using simulations and a simple mean-field theory, we investigate jamming transitions in a two-species lattice gas under non-equilibrium steady-state conditions. The two types of pa…
