Stable Thin Clathrate Layers
Eva Pospíšilová
We explore elemental Si, Ge and Sn free-standing slabs in diamond, clathrate and other competing structures and evaluate their stability by comparing Kohn-Sham total energies at th…

Full nonuniversality of the symmetric 16-vertex model on the square lattice
Eva Pospíšilová, Roman Krčmár, Andrej Gendiar +1
We consider the symmetric two-state 16-vertex model on the square lattice whose vertex weights are invariant under any permutation of adjacent edge states. The vertex-weight parame…
