Tensor network formalisms have emerged as powerful tools for simulating quantum state evolution. While widely applied in the study of optical quantum circuits, such as boson sampling, existing tensor network approaches f...

"Aquest llibre és un conjunt de problemes de física quàntica ordenats temàticament i pensats per a estudiants de grau, de ciències o denginyeria. Cada tema conté una breu introducció teòrica seguida dun recull de...

Tetragonal NdMn[Formula: see text]Ge[Formula: see text], a material exhibiting multiple non-collinear magnetic ordering phases, holds significant application potential. Herein, we systematically investigate the magnetic ...

We generalize a result on the Heisenberg Lie algebra that gives restrictions to possible Lie bialgebra cobrackets on 2-step nilpotent algebras with some additional properties. For the class of 2-step nilpotent Lie algebr...

Abstract We investigate the spin dynamics of a 1D spin-1/2 Heisenberg tetramer chain. Employing a combination of density matrix renormalization group, quantum renormalization group, and perturbation theory techniques, we...

We propose a simple method for generating spin squeezing of atomic ensembles in a Floquet cavity subject to a weak, detuned two-photon driving. We demonstrate that the weak squeezing of light inside the cavity can, count...

La presente tesis está enfocada al estudio de las propiedades del estado fundamental de sistemas tanto de electrones como de espines en bajas dimensiones. En la primera parte nos centramos en la problemática de los sis...

Los sistemas altamente correlacionados presentan una amplia variedad de fascinantes propiedades y se están estudiando de forma intensa desde hace ya varios años. Particularmente, desde el descubrimiento de los cupratos...

A new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists. The possibility of a phase transition characterized by a change in ...
