Friction and wear remain as the primary modes of mechanical energy dissipation in moving
mechanical assemblies; thus, it is desirable to minimize friction in a number of applications …

We measure isotope shifts for five Yb+ isotopes with zero nuclear spin on two narrow optical
quadrupole transitions S 2 1/2→ D 2 3/2, S 2 1/2→ D 2 5/2 with an accuracy of∼ 300 Hz …

Experimental results are presented on the efficiency limits for a quantum interface between a
matter-based qubit and a photonic qubit. Using a trapped ion in an optical cavity, we obtain …

We propose a hardware architecture and protocol for connecting many local quantum
processors contained within an optical cavity. The scheme is compatible with trapped ions or …

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 …

We prepare a maximally entangled state of two ions and couple both ions to the mode of an
optical cavity. The phase of the entangled state determines the collective interaction of the …

Friction between ordered, atomically smooth surfaces at the nanoscale (nanofriction) is often
governed by stick-slip processes. To test long-standing atomistic models of such processes …

We present and characterize fiber mirrors and a miniaturized ion-trap design developed to
integrate a fiber-based Fabry-Perot cavity (FFPC) with a linear Paul trap for use in cavity …

The highly nonlinear many-body physics of a chain of mutually interacting atoms in contact
with a periodic substrate gives rise to complex static and dynamical phenomena, such as …

Our ability to control friction remains modest, as our understanding of the underlying
microscopic processes is incomplete,,. Atomic force experiments,,,,,,,,,, have provided a …
