Constrained Dynamics of Tachyon Field in FRWL Spacetime
Marko A. Dimitrijević, Dragoljub D. Dimitrijević, Goran Djordjevic +1
In this paper we continue study of tachyon scalar field described by a Dirac-Born-Infeld (DBI) type action with constraints in the cosmological context. The proposed extension of t…
Generalized Bloch theorem and topological characterization
E. Dobardžić, M. Dimitrijević, M. V. Milovanović
The Bloch theorem enables reduction of the eigenvalue problem of the single-particle Hamiltonian that commutes with translational group. Based on a group theory analysis we present…
Effective description of Chern insulators
E. Dobardžić, M. Dimitrijević, M. V. Milovanović
The Berry curvature in Chern insulators appears to be a non-gauge-invariant quantity and does not immediately allow local length characterization. However, in two examples of 2- an…
