We study a quantum Otto engine operating on the basis of a helical spin-1/2 multiferroic
chain with strongly coupled magnetic and ferroelectric order parameters. The presence of a …

A quantum thermodynamic cycle with a chiral multiferroic working substance such as LiCu 2
O 2 is presented. Shortcuts to adiabaticity are employed to achieve an efficient, finite-time …

Quantum phase transitions are studied in the nonchiral p-clock chain, and a new explicitly U
(1)-symmetric clock model, by monitoring the ground-state fidelity susceptibility. For p≥ 5 …

Quantum dynamics of magnetic order in a chiral multiferroic chain is studied. We consider
two different scenarios: ultrashort terahertz excitations or a sudden electric field quench …

Many-body localization (MBL) is an emergent phase in correlated quantum systems with
promising applications, particularly in quantum information. Here, we unveil the existence …

An innovative way to produce quantum Hall ribbons in a cold atomic system is to use M
hyperfine states of atoms in a one-dimensional optical lattice to mimic an additional …

Qubit (s) transfer through a helical chain is studied. We consider the transfer of a single state
and Bell states across a multiferroic spin chain and the possibility of an electric-field control …

The dissipative dynamics of the spin chain coupled to the non-Markovian magnonic
reservoir was studied. The chirality of the chain is formed due to the magnetoelectric …

We demonstrate the generation and control of polaritonic states in perovskite phonon
polaritons, which are strongly coupled in the middle of a flexible Fabry–Perot cavity. We …

We develop a theoretical description of electromagnon solitons in a coupled ferroelectric-
ferromagnetic heterostructure. The solitons are considered in the weakly nonlinear limit as a …
