We introduce an integrable spin ladder model and study its exact solution, correlation functions, and entanglement properties. The model supports two particle types (corresponding to the even and odd sub-lattices), such that the scattering phases are constants: particles of the same type scatter as free fermions, whereas the inter-particle phase shift is a constant tuned by an interaction parameter. Therefore, the spin ladder bears similarities with anyonic models. We present exact results for…

Integrable deformations of superintegrable quantum circuits

Superintegrable models are very special dynamical systems: they possess more conservation laws than what is necessary for complete integrability. This severely constrains their dynamical processes,

Exploring quantum phase transitions with a sublattice entanglement scenario

We introduce a new measure called reduced entropy of sublattice to quantify entanglement in spin, electron and boson systems. By analyzing this quantity, we reveal an intriguing connection between

Sublattice entanglement and quantum phase transitions in antiferromagnetic spin chains

Entanglement of the ground states in the S = 1/2 XXZ chain, dimerized Heisenberg spin chain, two-leg spin ladders as well as S = 1 anisotropic Haldane chain is analysed using the entanglement entropy

Even-odd entanglement in boson and spin systems

We examine the entanglement entropy of the even half of a translationally invariant finite chain or lattice in its ground state. This entropy measures the entanglement between the even and odd halves

Entanglement Entropy of Periodic Sublattices

It is demonstrated that for a sufficiently large periodic sublattice the EE grows extensively, even in the vacuum, and the analytic expression for the EE allows us to probe its behavior both in the massless limit and in the continuum limit at any temperature.

I solve a quantum chain whose Hamiltonian is comprised solely of local four-fermi operators by constructing free-fermion raising and lowering operators. The free-fermion operators are both non-local

Cooper pairs and exclusion statistics from coupled free-fermion chains

We show how to couple two free-fermion chains so that the excitations consist of Cooper pairs with zero energy, and free particles obeying (mutual) exclusion statistics. This behaviour is reminiscent

Integrable spin chain with Hilbert space fragmentation and solvable real-time dynamics.

It is argued that this spin-1/2 chain is one of the simplest quantum integrable models, yet it has quite remarkable physical properties, and a nonlocal map is constructed that connects the model with the Maassarani-Mathieu spin chain, also known as the SU(3) XX model.

Ground-state properties of hard-core anyons in one-dimensional optical lattices

We investigate the ground-state properties of anyons confined in one-dimensional optical lattices with a weak harmonic trap using the exact numerical method based on Jordan-Wigner transformation. It

Quench dynamics and relaxation in isolated integrable quantum spin chains

We review the dynamics after quantum quenches in integrable quantum spin chains. We give a pedagogical introduction to relaxation in isolated quantum systems, and discuss the description of the

Comb entanglement in quantum spin chains

Bipartite entanglement in the ground state of a chain of N quantum spins can be quantified either by computing pairwise concurrence or by dividing the chain into two complementary subsystems. In the
