  2. 1. Bound states and resonances in three-body system

    Author : Yarevsky Evgeny; Thomas N. Rescigno; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Three-body problem; Total angular momentum representation; Resonances; Complex Scaling Method; Finite Element Method; Eigenvalues problem.; Physics; fysik;

    Abstract : The quantum three-body problem plays an important role in different branches of the modern physics. In the nuclear, atomic and molecular physics there exist a number of systems whose behaviour is naturally described in this framework. READ MORE

  4. 2. Resonances in Three-Body Systems

    Author : Muhammad Umair; Svante Jonsell; Yasushi Kino; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : Three particles interacting via Coulomb forces represent a fundamental problem in quantum mechanics with no known exact solution. We have investigated resonance states composed of three particles interacting via Coulombic and more general potentials in non-relativistic quantum mechanics, using the complex scaling method.

  5. 3. Resonances in three-body systems

    Author : Muhammad Umair; Svante Jonsell; Michael Odelius; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : Three particles interacting via Coulomb forces represents a fundamental problem in quantum mechanics whose approximate solution provides some insight into the more complex analysis associated with few-body problems. We have investigated resonance states composed of three particles interacting via Coulombic and more general potentials in non-relativistic quantum mechanics, using the complex scaling method.

  6. 4. Three-body Universality Controlled by a Feshbach Resonance

    Author : Kajsa-My Tempest; Svante Jonsell; Doerte Blume; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Efimov states; few-body systems; ultracold atoms; van der Waals interaction; Feshbach resonances; universality; computational studies; Theoretical Physics; teoretisk fysik;

    Abstract : The quantum Efimov effect manifests itself in the limit of resonant two-body interactions, where the scattering length diverges. In this scenario, an infinite number of shallow bound trimer states are formed with binding energies that obey a discrete geometric scaling law. READ MORE
