We predict the instability of the quantum spin-1 chain material with respect to the spin
nematic ordering. For the spin subsystem the spin nematic order parameter is related to the …

Spin-1 chain material is considered. Recently, it was predicted that the spin nematic ordered
phase can be realized due to the spin-elastic coupling. In this study we show that the …

The piezomagnetoelectric effect is considered to be the appearance of a piezoelectric
response caused by a magnetic field in magnetically ordered media. The possibility of its …

A spin-1/2 chain system coupled to the elastic subsystem of the crystal is considered. Due to
that coupling, the intersite spin nematic ordering in the spin subsystem takes place. The …

Using the exact Bethe ansatz solution, a one-dimensional correlated electron system
coupled to the lattice is considered. Electrons belonging to two orbital bands interact via the …

The theory for the low-temperature behavior of sound velocities (and related elastic
modules) in the external magnetic field in UTe 2 is proposed. The theory is based on the …

Using Raman and infrared spectroscopies, spontaneous ferriquadrupolar ordering has been
observed in the rare-earth-based system KDy (MoO 4) 2. Ordered quadrupoles in the …

Using Raman and infrared spectroscopies the spontaneous ferriquadrupolar ordering has
been observed in the rare-earth-based system KDy (MoO $ _4 $) $ _2 $. Ordered …
