  • Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.
  • Abstract Speckle patterns produced by multiple independent light sources are a manifestation of the coherence of the light field. Second-order correlations exhibited in phenomena such as photon bunching, termed the Hanbury Brown–Twiss effect, are a measure of quantum coherence. Here we observe for the first time atomic speckle produced by atoms transmitted through an optical waveguide, and link this to second-order correlations of the atomic arrival times. We show that multimode matter-wave guiding, which is directly analogous to multimode light guiding in optical fibres, produces a speckled transverse intensity pattern and atom bunching, whereas single-mode guiding of atoms that are output-coupled from a Bose–Einstein condensate yields a smooth intensity profile and a second-order correlation value of unity. Both first- and second-order coherence are important for applications requiring a fully coherent atomic source, such as squeezed-atom interferometry.

  • A study that evaluated the relative efficacy of four types of treatment for people with comorbid diagnoses showed that conclu-sions about the efficacy of the different therapeutic approaches changed depending on the nature of the outcome measure used.
  • Cognitive behavioral therapy is underpinned by the proposition that emotions and behavior are influenced by cognitions
  • We began with the ‘classical’ psychoanalytic psychotherapies, moving to some recent developments, such as the relational and attachment-based psychotherapies, and intensive short-term dynamic psychotherapy (ISTDP), followed by the behavioral, cognitive, and cognitive behavioral therapies, including the ‘new wave’ of therapies such as mindfulness-based therapies, acceptance and commitment therapy (ACT) and dialectical behavior therapy (DBT).

  • Three groups of therapies—behavioral, cognitive, and cognitive behavioral—are all based on the same principles, but use the available therapeutic techniques in different amounts.
  • These researchers identified six techniques/interventions that are unique to CBT when compared with the spectrum of psychodynamic-interpersonal psycho-therapies, as follows
