We theoretically investigate atomic frustrated states in diatomic molecules hosted by the bilayer graphene setup twisted first magic angle and with broken inversion symmetry Dirac cones of system mini Brillouin zones. Such show local spectral features typically from uncoupled atoms, but counterintuitively, they also exhibit nonlocal molecular correlations, which turn them into atomically frustr...

Structural frustration in a rod packing exhibits analogy to frustration effects in antiferromagnetic systems. Like the spins in a triangular Ising net, rods with periodic contour may arrange randomly. Such frustration effects are observed in rare earth metal carbide nitride halides composed of C2 centered RE6 octahedra and N centered RE4 tetrahedra. These can be connected in varying sequences t...

In magnetism, of which molecular magnetism is a part, the term frustration is used rather sloppily. Sometimes one gains the impression that if the reason for some phenomenon is not quite clear then it is attributed to frustration. In this paper a discussion of the effects of frustration that are relevant for the field of molecular magnetism is presented. As will become clear later these effects...

Frustration is an important phenomenon in condensed matter physics because it can introduce a new order parameter such as chirality. Towards understanding a mechanism of the frustration in strongly correlated systems, we study a holographic superconductor model with three scalar fields and an interband Josephson coupling, which is important for the frustration. We analyze free energy of solutio...

We find Cu2(AsO4)(OH)·3H2O (euchroite) is a model compound for the frustrated delta chain which is composed of corner-sharing triangles. Magnetic susceptibility, specific heat, high field magnetization and H-NMR measurements are carried out using natural mineral samples of euchroite to study magnetic properties. Large spin gap of about 100 K is shown to be presented in this compound. ∗Present a...
