Three-dimensional structure and stability of discontinuities between unmagnetized pair plasma and magnetized electron-proton plasma
M E Dieckmann, D Folini, M Falk +3
We study with a 3D PIC simulation discontinuities between an electron-positron pair plasma and magnetized electrons and protons. A pair plasma is injected at one simulation boundar…
Collisionless Rayleigh-Taylor-like instability of the boundary between a hot pair plasma and an electron-proton plasma: the undular mode
M E Dieckmann, M Falk, D Folini +4
We study with a two-dimensional particle-in-cell simulation the stability of a discontinuity or piston, which separates an electron-positron cloud from a cooler electron-proton pla…
Inviwo -- A Visualization System with Usage Abstraction Levels
Daniel Jönsson, Peter Steneteg, Erik Sundén +6
The complexity of today's visualization applications demands specific visualization systems tailored for the development of these applications. Frequently, such systems utilize lev…
Finite temperature elastic constants of paramagnetic materials within the disordered local moment picture from ab initio molecular dynamics calculations
Elham Mozafari, Nina Shulumba, Peter Steneteg +2
We present a theoretical scheme to calculate the elastic constants of magnetic materials in the high-temperature paramagnetic state. Our approach is based on a combination of disor…
The role of N defects in paramagnetic CrN at finite temperatures from first-principles
Elham Mozafari, Björn Alling, Peter Steneteg +1
Simulations of defects in paramagnetic materials at high temperature constitute a formidable challenge to solid state theory due to the interaction of magnetic disorder, vibrations…
Vibrational free energy and phase stability of paramagnetic and antiferromagnetic CrN from ab-initio molecular dynamics
Nina Shulumba, Björn Alling, Olle Hellman +4
We present a theoretical first-principles method to calculate the free energy of a magnetic system in its high-temperature paramagnetic phase, including vibrational, electronic, an…
Temperature dependent effective potential method for accurate free energy calculations of solids
Olle Hellman, Peter Steneteg, Igor A. Abrikosov +1
We have developed a thorough and accurate method of determining anharmonic free energies, the temperature dependent effective potential technique (TDEP). It is based on \emph{ab in…
Effects of configurational disorder on adatom mobilities on TiAlN(001) surfaces
B. Alling, P. Steneteg, C. Tholander +4
We use metastable NaCl-structure Ti0.5Al0.5N alloys to probe effects of configurational disorder on adatom surface diffusion dynamics which control phase stability and nanostructur…
Extended Lagrangian free energy molecular dynamics
Anders M. N. Niklasson, Peter Steneteg, Nicolas Bock
Extended free energy Lagrangians are proposed for first principles molecular dynamics simulations at finite electronic temperatures for plane-wave pseudopotential and local orbital…
Equation of state of paramagnetic CrN from ab initio molecular dynamics
Peter Steneteg, Björn Alling, Igor A. Abrikosov
Equation of state for chromium nitride has been debated in the literature in connection with a proposed collapse of its bulk modulus following the pressure induced transition from…
Wavefunction extended Lagrangian Born-Oppenheimer molecular dynamics
Peter Steneteg, Igor A. Abrikosov, Valery Weber +1
Extended Lagrangian Born-Oppenheimer molecular dynamics [Niklasson, Phys. Rev. Lett. 100 123004 (2008)] has been generalized to the propagation of the electronic wavefunctions. The…
