“…to cool the charged antiparticle constituents by way of resistive cooling [ 135 ] before recombining them. The nearby surface may also enable efficient multi-species traps as required for this experiment, while the high gradients may allow efficient recombination processes [ 136 ]. One of the challenges concerns the final temperature of the antihydrogen.…”

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC) as well as cold matter in general. Twenty years after the first realization of the BEC and 15 years after the realization of the atom chip, the latter has been found to enable extraordinary feats: from producing BECs at a rate of several per second, through the realization of matter-wave interferometry, and all the way to novel probing of surfaces and new forces. In addition, technological applications are also being intensively pursued. This review will describe these developments and more, including new ideas which have not yet been realized.

“…Paul traps are used to investigate chemical reactions of ions at low temperatures [37], and two-frequency operation allows much heavier species to be used without a large spatial separation. This application is closely related to the use of two frequencies for the confinement of antimatter where the creation of overlapping clouds of positrons and anti-protons leads to the formation of anti-hydrogen atoms; work towards this is technically challenging goal is ongoing [14] 3 .…”

“…Here we propose an approach motivated by an aspect of electrodynamic trapping -hinted at by Dehmelt in a one-page bulletin on confinement of antimatter [13] -that has received little attention. Dehmelt suggested using electric fields oscillating at two suitably chosen frequencies to simultaneously confine charged particles with different Q/M; this idea has recently been explored further in [14]. We show that the same principle can be used to confine atomic ions and heavier charged molecules.…”

We describe the operation of an electrodynamic ion trap in which the electric quadrupole field oscillates at two frequencies. This mode of operation allows simultaneous tight confinement of ions with extremely different charge-to-mass ratios, e.g., singly ionised atomic ions together with multiply charged nanoparticles. We derive the stability conditions for two-frequency operation from asymptotic properties of the solutions of the Mathieu equation and give a general treatment of the effect of damping on parametric resonances. Two-frequency operation is effective when the two species' mass ratios and charge ratios are sufficiently large, and further when the frequencies required to optimally trap each species are widely separated. This system resembles two coincident Paul traps, each operating close to a frequency optimized for one of the species, such that both species are tightly confined. This method of operation provides an advantage over single-frequency Paul traps, in which the more weakly confined species forms a sheath around a central core of tightly confined ions. We verify these ideas using numerical simulations and by measuring the parametric heating induced in experiments by the additional driving frequency.

We propose and analyze magnetic traps and lattices for electrons in semiconductors. We provide a general theoretical framework and show that thermally stable traps can be generated by magnetically driving the particle's internal spin transition, akin to optical dipole traps for ultra-cold atoms. Next we discuss in detail periodic arrays of magnetic traps, i.e. magnetic lattices, as a platform for quantum simulation of exotic Hubbard models, with lattice parameters that can be tuned in real time. Our scheme can be readily implemented in state-of-the-art experiments, as we particularize for two specific setups, one based on a superconducting circuit and another one based on surface acoustic waves.
