  1. 237. Quantum Computing Challenges for Transition Dynamics in Atomic and Molecular Systems (S04-AMP-001)
    Predrag S. Krstic (Institute for Advanced Computational Science, Stony Brook University)

    S04 Atomic and Molecular Physics
    Invited talk (virtual)

    Quantum computing (QC), based on principles of superposition, entanglement, and measurement of qubits, promises the advantage to surpass the performance of classical computing in cryptography, communication, and optimization problems, as well as in simulations of complex quantum system in physics and computation chemistry. Despite decades in development, fully coherent, fault-free universal...

    S04 Atomic and Molecular Physics
    Invited talk (virtual)

    In this talk I will review the very recent experiments conducted by my group on various quantum control techniques at some of the open-access IBM quantum processors. I particular, I will show results on quantum control by composite pulses, quantum control by polychromatic pulse trains, quantum sensing of small frequency shifts, tuning the parameters of the quantum computer, dynamical...

  3. 184. NS super-excited molecular states in the collision of electrons with NS+ cation (S04-AMP-101)

    Oral presentation

    The recent discovery of the NS+ cation in the interstellar medium1 triggered the interest in the study of its collision with electrons. In this complex process, the electron can be captured into NS Rydberg-bound states predissociated by Feshbach resonances of this latter molecule. These both types of states have been calculated within the Born-Oppenheimer approximation using a variationa...

  4. 128. Compound-state model for non-sequential double ionization (S04-AMP-102)
    Prof. Nenad Simonović (Institute of Physics Belgrade)

    S04 Atomic and Molecular Physics
    Oral presentation

    Non-sequential double ionization (NSDI) is a strong-field atomic process in which two electrons simultaneously leave atom irradiated by an intense laser pulse.$^1$ This process has been described successfully by the three-step (TS) model. The first step of this model is the process of tunneling an atomic electron through the barrier which is formed by combining the atomic potential with the...

  5. 29. Tribological Properties of Selected Vanadium Oxide Stoichiometries Studied with Reactive Molecular Dynamics (S04-AMP-100)
    Dr Miljan Dašić (Scientific Computing Laboratory, Center for the Study of Complex Systems,Institute of Physics Belgrade, University of Belgrade )
    01/09/2022, 12:30
    S04 Atomic and Molecular Physics
    Oral presentation

    Providing effective lubrication at high temperatures/pressures and in oxidative environments is relevant for various industrial applications, such as turbomachinery and cutting tools [1,2]. Promising solutions for such conditions are oxidation-resistant hard coatings consisting of binary or ternary films (Cr-N, Ti-N, Cr-Al-N, Ti-Al-N) doped with an additional element which can diffuse to the...
