Book excerpt: This thesis lays the groundwork for producing a new class of ultracold molecule by associating an alkali-metal atom and a closed-shell alkaline-earth-like atom, specifically Cs and Yb. Such molecules exhibit both a magnetic dipole moment and an electric dipole moment in their ground state. This extra degree of freedom opens up new avenues of research including the study of exotic states of matter, the shielding of molecular collisions and the simulation of lattice spin models. In detail, the thesis reports the first and only ultracold mixture of Cs and Yb in the world, giving details of the methods used to cool such contrasting atomic species together. Using sensitive two-colour photoassociation measurements to measure the binding energies of the near-threshold CsYb molecular levels in the electronic ground state has allowed the previously unknown scattering lengths to be accurately determined for all the Cs–Yb isotopic combinations. As part of this work, the one-photon photoassociation of ultracold Cs*Yb is also studied, yielding useful information on the excited-state potential. Knowledge of the scattering lengths enables a strategy to be devised to cool both species to quantum degeneracy and, crucially, determines the positions of interspecies Feshbach resonances required for efficient association of ground-state CsYb molecules. With these results, the prospect of bringing a new molecule into the ultracold regime has become considerably closer.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen tremendous progress in research on cold and controlled molecular collisions, both in theory and in experiment. The advent of techniques to prepare cold and ultracold molecules and ions, to store them in optical lattices or in charged quasicristalline structures, and to use them in crossed or merged beam experiments have opened many new possibilities to study the most fundamental aspects of molecular interactions. At the same time, theoretical work has made progress in tackling these problems and accurately describing quantum effects in complex systems, and in proposing viable options to control chemical reactions at ultralow energies. Through tutorials on both the theoretical and experimental aspects of research in cold and ultracold molecular collisions, this book provides advanced undergraduate students, graduate students and researchers with the foundations needed to understand this exciting field.

Book excerpt: Electric dipole moments (EDMs) have interested physicists since 1950, when it was first suggested that there was no experimental evidence that nuclear forces are symmetric under parity (P) transformation. This question was regarded as speculative because the existence of an EDM, in addition to P violation, requires a violation of time-reversal (T) symmetry. In 1964 it was discovered that the invariance under CP transformation, which combines charge conjugation (C) with parity, is violated in K-meson decays. This provided a new incentive for EDM searches. Since the combined operations of CPT are expected to leave a system invariant, breakdown of CP invariance should be accompanied by a violation of time-reversal symmetry. Thus there is a reason to expect that EDMs should exist at some level. The original neutron EDM experiments were later supplemented with checks of T invariance in atoms and molecules. These investigations are pursued now by many groups. Over the years, the upper limit on the neutron EDM has been improved by seven orders of magnitude, and the upper limit on the electron EDM obtained in atomic experiments is even more strict.

Book excerpt: A straightforward, easy-to-understand book that teaches you how to directly communicate with animals. Animal Talk teaches you how to open the door to your animal friends’ hearts and minds without resorting to magic tricks or wishful thinking. Every creature can be reached through telepathic communication—from your tabby cat or cockatiel to the wasps that build nests in the eaves of your home or even the common flea—you just have to be open to the idea, and mind-to-mind communication will be in your grasp. In addition to an entire chapter devoted to teaching people how to develop mind-to-mind communication with animals, Animal Talk includes a discussion of freedom, control, and obedience, understanding behaviors from the animal’s point of view, how to handle upsets between animals, tips on nutrition for healthier pets, and the special relationship between animals and children.

Book excerpt: "There have been enormous recent advances in our ability to produce and trap samples of translationally cold molecules (below 1 K) and ultracold molecules (below 1 mK). Molecules such as NH3, OH and NH have been cooled from room temperature to the milliKelvin regime by a variety of methods including buffer-gas cooling and Stark deceleration. Molecules have also been produced in ultracold atomic gases by photoassociation and magnetoassociation of pairs of atoms. Bose-Einstein condensates have been produced for dimers of both bosonic and fermionic alkali metal atoms, and the first signatures of ultracold triatomic and tetraatomic molecules have been observed. The new capabilities open up many exciting prospects, including: the study of collision processes in unprecedented detail using cooled or velocity-controlled species; the use of cold molecules in high-precision measurement to observe fundamentally important quantities; the production of quantum gases of dipolar molecules, which would exhibit many new properties; the use of cold molecules as qubits in quantum computing; and controlled ultracold chemistry, in which controlled chemical changes are achieved coherently for large samples using external fields."--Publisher's description.
