We study a Hamiltonian system describing a three-spin-1/2 clusterlike interaction competing
with an Ising-like antiferromagnetic interaction. We compute free energy, spin-correlation …

The symmetry-resolved Rényi entanglement entropy is the Rényi entanglement entropy of
each symmetry sector of a density matrix ρ. This experimentally relevant quantity is known to …

We study the scaling properties of the ground-state entanglement between finite subsystems
of infinite two-dimensional free lattice models, as measured by the logarithmic negativity. For …

We study the Rényi entanglement entropy of an interval in a periodic fermionic chain for a
general eigenstate of a free, translational invariant Hamiltonian. In order to analytically …

We obtain a formula for the determinant of a block Toeplitz matrix associated with a
quadratic fermionic chain with complex coupling. Such couplings break reflection symmetry …

We report a dynamical quantum phase transition portrait in the alternating field transverse
XY spin chain with Dzyaloshinskii-Moriya interaction by investigating singularities in the …

In this paper, a one-dimensional spin-1/2 Ising model in a transverse magnetic field (ITF)
with added the transverse Dzyaloshinskii-Moriya (DM) interaction is considered. The …

We study the dynamics of the transverse field Ising chain after a local quench in which two
independently thermalised chains are joined together and are left to evolve unitarily. In the …

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 …

The key dynamic properties of fermionic systems, like controllability, reachability, and
simulability, are investigated in a general Lie-theoretical frame for quantum systems theory …
