We present an up-to-date survey of theoretical concepts and results in the field of one-
dimensional magnetism and of their relevance to experiments and real materials. Main …

We study theoretically the nonlinear optical response of Tomonaga-Luttinger spin liquid in
the context of terahertz (THz) two-dimensional coherent spectroscopy (2DCS). Using the …

A prominent feature of quantum spin liquids is fractionalization of the spin degree of
freedom. Fractionalized excitations have their own dynamics in different energy scales, and …

By the hydrodynamic linear response theory, dynamical correlation functions decay as
power laws along certain velocities, determined by the flux Jacobian. Such correlations are …

We consider the spin-1 2 anisotropic XY chain in a transverse (z) field with the
Dzyaloshinskii-Moriya interaction directed along the z axis in spin space to examine the …

We present a flexible density-matrix renormalization group approach to calculate finite-
temperature spectral functions of one-dimensional strongly correlated quantum systems …

The spin-1/2 quantum transverse Ising model, defined on a ladder structure, with nearest-
neighbor and four-spin interaction on a plaquette, was studied by using exact …

We consider a spin-1 2 XY chain in a transverse (z) field with multisite interactions. The
additional terms introduced into the Hamiltonian involve products of spin components …

The equilibrium dynamics of the spin-1 2 XX chain is reexamined within a recently
developed formalism based on the quantum transfer matrix and a thermal form-factor …

The notion of geometric phase has been recently introduced to analyze the quantum phase
transitions of many-body systems from the geometrical perspective. In this work, we study …
