Spin models of quasi-1D quantum ferrimagnets with competing interactions
We present a brief survey of the recent theoretical work related to generic Heisenberg spin models describing quasi-one-dimensional quantum ferrimagnets. The emphasis is on quantum chains and ladders with strong competing interactions, such as the frustrated J₁ - J₂ chain with alternating (1, 1/2)...

We present a brief survey of the recent theoretical work related to generic Heisenberg spin models describing
quasi-one-dimensional quantum ferrimagnets. The emphasis is on quantum chains and ladders with strong
competing interactions, such as the frustrated J₁ - J₂ chain with alternating (1, 1/2) spins, the spin-1/2
diamond chain with four-spin cyclic couplings, and some generic types of mixed-spin ladders with geometric
frustration. As a rule, the discussed models exhibit rich quantum phase diagrams and provide some interesting
examples of one-dimensional magnetic-paramagnetic quantum phase transitions. A number of open problems
in the reviewed research area are discussed. |
