“…An interferometric apparatus has recently been proposed for the study of gravitational interactions of anti-hydrogen atoms (see Refs. [40,41]); the tiny gravitational shift of the interference pattern from atoms, after passing through a grating, should enable a test of Einstein's equivalence principle for antimatter (this is the main conceptual idea of the AGE Collaboration, see Ref. [41]).…”

The noncontact (van der Waals) friction is an interesting physical effect which has been the subject of controversial scientific discussion. The "direct" friction term due to the thermal fluctuations of the electromagnetic field leads to a friction force proportional to 1/Z 5 (where Z is the atom-wall distance). The "backaction" friction term takes into account the feedback of thermal fluctuations of the atomic dipole moment onto the motion of the atom and scales as 1/Z 8 . We investigate noncontact friction effects for the interactions of hydrogen, ground-state helium and metastable helium atoms with α-quartz (SiO2), gold (Au) and calcium difluorite (CaF2). We find that the backaction term dominates over the direct term induced by the thermal electromagnetic fluctuations inside the material, over wide distance ranges. The friction coefficients obtained for gold are smaller than those for SiO2 and CaF2 by several orders of magnitude.

“…With the end of the Tevatron Collider program in sight, new and unique measurements are possible at the Fermilab Antiproton Source [49,50]. If approved, such a program will substantially broaden the clientele and appeal of US particle physics.…”

Fermilab operates the world's most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes in about 2011. For example, the annihilation of 8 GeV antiprotons might make the world's most intense source of tagged D 0 mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other potential measurements include sensitive studies of hyperons and of the mysterious X, Y , and Z states. Production of antihydrogen in flight can be used for first searches for antihydrogen CPT violation. With antiproton deceleration to low energy, an experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter.
