Davide Sangiovanni

Associate Professor, Docent

I am associate professor and docent. My research aims at understanding electronic mechanisms and atomistic phenomena that control the mechanical properties, phase transformations, and surface reactivity of metals and ceramics.

Presentation

My research activities – based on calculations and simulations on supercomputers – include:

  • (i) Bottom-up design of refractory ceramic alloys and superlattices that retain high mechanical strength, hardness, and toughness from room to elevated (> 1000 ºC) temperatures.
     
  • (ii) Gaining atomistic and electronic-scale knowledge of gas/surface reactions and mass transport on bulk and 2D materials for applications in crystal growth, catalysis, and oxidation-resistant coatings
    . 
  • (iii) Determination of thermodynamic and kinetic conditions for phase transformation and phase segregation in alloys.
    . 
  • (iv) Development of theoretical methods and models for evaluation of material properties at conditions of relevance for practical uses.

Teaching

I am also responsible for the Computational Physics course (4th year students), as well as assistant/lecturer in other undergraduate courses.

Theoretical Physics

Theoretical physics deals with understanding of nature. In our research we use fundamental principles and basic concepts to develop mathematical models that are then studied by means of analytical and numerical methods.

Chains of atoms move at lightning speed inside metals

A phenomenon that has been seen when researchers simulate the properties of planet cores at extreme pressures has now been observed in pure titanium at atmospheric pressure. Chains of atoms dash around at lightning speeds inside the solid material.
