Macroscopic degeneracy of ground state in the frustrated Heisenberg diamond chain
D. V. Dmitriev, V. Ya. Krivnov
The spin- Heisenberg diamond chain with ferro- and antiferromagnetic exchange interactions is studied. The phase boundary in the parametric space of these interactions…
Magnetospheric accretion at the late phases of the Pre-Main-Sequence evolution. The case of RZ Psc
D. V. Dmitriev, V. P. Grinin, I. S. Potravnov +1
It has been shown that during the outburst of accretion activity observed in UX Ori type star RZ Psc in 2013, the accretion rate increased approximately by an order of magnitude. T…
Anomalous thermodynamics of a quantum spin system with large residual entropy
J. Richter, J. Schulenburg, D. V. Dmitriev +2
In contrast to strongly frustrated classical systems, their quantum counterparts typically have a non-degenerate ground state. A counterexample is the celebrated Heisenberg sawtoot…
The delta-chain with ferro- and antiferromagnetic interactions in applied magnetic field
D. V. Dmitriev, V. Ya. Krivnov, J. Schnack +1
We study the thermodynamics of the delta-chain with competing ferro- and antiferromagnetic interactions in an external magnetic field which generalizes the field-free case studied…
Thermodynamics of delta-chain with ferro- and antiferromagnetic interactions
D. V. Dmitriev, V. Ya. Krivnov, J. Richter +1
Motivated by a novel cyclic compound with record ground state spin in which the arrangement of magnetic ions with and corresponds t…
Heisenberg-Ising delta-chain with bond alternation
D. V. Dmitriev, V. Ya. Krivnov
The spin- delta-chain (sawtooth chain) with antiferromagnetic Heisenberg basal chain and Ising apical-basal interactions is studied. The basal-apical interactions invo…
