Quantitative disorder effects in low-dimensional spin systems.
Spintronics is the physics of low-dimensional quantum spin systems. The eld of low-dimensional magnetism was established in the wake of quantum mechanics through two ground-breaking theoretical achievements: rst, the introduction of the one-dimensional Ising model in 1925 [11], and second, the exact calculation of the ground.

Significant quantum fluctuations in low-dimensional spin frustrated systems can give rise to novel quantum phases and exotic quantum phase transitions. [1-5] One substantial difference from the classical systems is that in these quantum spin systems, some phases can not be characterized by conventional order parameters with broken symmetry. On low-dimensional magnetic insulators [ii,2-15] have given strong evidence for the presence of a third channel for heat transport, namely a contribution of magnetic excitations. This thesis studies the transport properties of low-dimensional quantum spin models, including transport of spin or magnetization and heat transport.
Confinement Quantum Dimension In One.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The Jordan-Wigner transformation is known as a powerful tool in condensed matter theory, especially in the theory of low-dimensional quantum spin systems. The aim of this chapter is to review the application of the Jordan-Wigner fermionization technique for calculating dynamic quantities of low-dimensional quantum. In particular, we demonstrate that, in order to obtain data with a similar level of noise in the classical case, extensive averaging over classical trajectories is required, no matter how large the system size. Focusing on (quasi-)one-dimensional spin chains and ladders, we find a remarkably good agreement between quantum and classical dynamics.

Tensor Network States and Effective Particles for Low-Dimensional.
Posted on April 01, 2014 by Web Services Editor. Solid state nuclear spin systems are an excellent platform on which to explore many-body quantum dynamics, as the spins are well-isolated from other degrees of freedom and the Hamiltonian of the system is well-known. We use the tools of magnetic resonance to engineer specific Hamiltonians in both. This method presumes a strong coupling between the spin states and the lattice, seen for example in low-dimensional quantum spin systems such as quasi-1D spin-Peierls systems. Indeed, recent magnetostriction measurements of SCBO in pulsed fields point to a sizeable coupling between the spins in the Cu dimers and the lattice.
NMR investigation of low dimensional quantum spin systems.
Physica E: Low-dimensional systems and nanostructures contains papers and invited review articles on the fundamental and applied aspects of physics in low-dimensional electron systems, in semiconductor heterostructures, oxide interfaces, quantum wells and superlattices, quantum wires and dots, novel quantum states of matter such as topological insulators, and Weyl semimetals. This book covers all principal aspects of currently investigated frustrated systems, from exactly solved frustrated models to real experimental frustrated systems, going through renormalization group treatment, Monte Carlo investigation of frustrated classical Ising and vector spin models, low-dimensional systems, spin ice and quantum spin glass.
Spin-Peierls transition in low-dimensional quantum spin.
Oct 21, 2011 · The compounds, CuCrO4 (3d9) and TiPO4 (3d1), are shown to have completely different ground states despite both being largely isostructural and S = 1/2 quantum spin systems. In this work and the resulting publications it is shown that CuCrO4 is a one-dimensional S = 1/2 spin chain with anti-ferromagnetic nearest- and next nearest-neighbour spin. We study low-dimensional quantum systems with analytical and computational methods. Firstly, the one-dimensional extended t-V model of fermions with interactions of finite range is investigated. The model exhibits a phase transition between liquid and insulating regimes. We use various analytical approaches to generalise previous theoretical studies.

Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are analytically challenging and exponentially.
PDF Correlations in Low-Dimensional Quantum Many-Particle Systems.
Quantum spin systems are insulating crystals containing regular array of atoms carrying spin S = 1/2 or 1, described by simple spin Hamiltonians. In low-dimensional model compounds, we study by Nuclear Magnetic Resonance (NMR), which is a microscopic probe to magnetism, the magnetic-field-induced "exotic" phases, such as the Bose-Einstein. Low-dimensional quantum spin systems are interacting many body systems for which several rigorous results are known. Powerful techniques like the Bethe Ansatz provide exact knowledge of the ground state energy and low-lying excitation spectrum. A large number of compounds exist which can effectively be described as low-dimensional spin systems. Thus.

Introduction. Low-dimensional magnets have long been a playground for discovering unconventional physics. 1-3 From an experimental point of view, ideal systems have strong magnetic coupling in one- or two-dimensional units, which are well isolated from each other. This includes magnetic chains, which are hosts to spinon quasi-particles that fractionalise electrons by carrying their spin but.

A central concept in describing these low-dimensional quantum spin systems is that of a spin liquid. This ground state is dominated by strong quantum fluctuations, pronounced spin–spin correlations and a suppression of long-range magnetic order. Low-dimensional quantum spin systems are interacting many body systems for which several rigorous results are known. Powerful techniques like.
