This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

A wide range of exotic bound systems incorporating antiprotons (atoms, atomic ions,
molecules or molecular ions) can be formed, in many cases simply by replacing at least one …

The simplest molecules in nature, molecular hydrogen ions in the form of H2+ and HD+,
provide an important benchmark system for tests of quantum electrodynamics in complex …

Charge, parity, and time reversal (CPT) symmetry implies that a particle and its antiparticle
have the same mass. The antiproton-to-electron mass ratio M p¯/me can be precisely …

We calculate ionization energies and fundamental vibrational transitions for H 2+, D 2+, and
HD+ molecular ions. The nonrelativistic quantum electrodynamics expansion for the energy …

The precise measurement of transition frequencies in cold, trapped molecules has
applications in fundamental physics, and extremely high accuracies are desirable. We …

When atoms are placed into liquids, their optical spectral lines corresponding to the
electronic transitions are greatly broadened compared to those of single, isolated atoms …

The quantum electrodynamic correction to the energy of the hydrogen molecule has been
evaluated without expansion in the electron-proton mass ratio. The obtained results …

Sympathetic cooling of trapped ions has been established as a powerful technique for the
manipulation of non-laser-coolable ions,,–. For molecular ions, it promises vastly enhanced …

Charged pions are the lightest and longest-lived mesons. Mesonic atoms are formed when
an orbital electron in an atom is replaced by a negatively charged meson. Laser …
