More information about the seminar

1. Seminar topic: “Method for simulating thermal processes in metals irradiated by particles on basis of development and combination of thermal spike and molecular dynamics models”

   Speaker: Z. K. Tukhliev

   Abstract:
   
   

   The talk provides an overview of the research performed using the molecular dynamics method and in combination with the thermal spike model over the past three years. The report has the following parts: 1) Numerical methods: algorithm optimisation, high-order schemes for systems with a small number of particles, use of high-performance systems. 2) Irradiation of materials with high-energy heavy ions. The applicability and modification of the molecular dynamics method in combination with the thermal spike model when irradiating materials with high-energy heavy ions are discussed. 3) Irradiation with nanoclusters. Wave effects of heat conduction, formation of shock waves and their influence on structural changes.




2. Seminar topic: “Analysis of quantum simulators and quantum algorithm modeling on “Govorun” supercomputer”

   Speaker: O. V. Ivancova

   Abstract:
   
   

   After decades of development, quantum computing has made tangible progress in hardware and algorithms. However, modern quantum devices are seriously limited in the number of qubits, the circuit depth and, at the same time, have strong noise processes that make it difficult to attain a correct result. Therefore, the direction related to software quantum simulators for calculations on classical computers is of particular interest. The talk provides a comparison of several quantum simulators using the classical architecture on the example of modeling three quantum algorithms and also presents the results of the effective use of a supercomputer to model quantum circuits on the CPU and GPU.
