We study the effect of the Dzyaloshinskii-Moriya (DM) interaction on the quantum speed limit
(QSL) and orthogonality catastrophe (OC) in XY spin chains. With an initial sudden quench …

We consider a simple integrable model of a spin chain exhibiting the magnetoelectric effect
(MEE). Starting from the periodic S= 1/2 XXZ chain with Dzyaloshinskii-Moriya terms, which …

We consider the exactly solvable spin-1/2 XX chain with the three-spin interactions of the
XZX+ YZY and XZY− YZX types in an external (transverse) magnetic field. We calculate the …

We consider a class of one-dimensional compass models with an XYZ-YZX type of three-site
exchange interaction in an external magnetic field. We present the exact solution derived by …

We illustrate the magnetoelectric effect conditioned by the Katsura-Nagaosa-Balatsky (KNB)
mechanism within the frames of exactly solvable spin-1/2 XY chains. Due to three-spin …

We study the quantum critical behavior of the XY spin chain with multisite interaction by
means of a fidelity susceptibility (FS) calculation. The key ingredients (eg, finite-size scaling …

We consider the isotropic Heisenberg model in a magnetic field in the strong-rung-coupling
limit on a two-dimensional (2D) rectangular zig-zag lattice of arbitrary size, and determine …

We study the dynamical quantum phase transitions (DQPTs) in the XY chains with the
Dzyaloshinskii–Moriya interaction and the XZY–YZX type of three-site interaction after a …

Chiral phase and quantum phase transitions of anisotropic XY chains with the XZY− YZX
type of three-site interaction are studied. The phase diagram is obtained by the study of the …

We present exact results for the ground-state and thermodynamic properties of the spin-1/2
XX chain with three-site interactions in a random (Lorentzian) transverse field. We discuss …
