We use a combination of three computational methods to investigate the notoriously difficult frustrated three-dimensional pyrochlore $S=\frac{1}{2}$ quantum antiferromagnet, at finite temperature $T$: canonical typicality for a finite cluster of $2\ifmmode\times\else\texttimes\fi{}2\ifmmode\times\else\texttimes\fi{}2$ unit cells (i.e., 32 sites), a finite-$T$ matrix product state method on a larger cluster with 48 sites, and the numerical linked cluster expansion (NLCE) using clusters up to 25… 

Possible Inversion Symmetry Breaking in the S=1/2 Pyrochlore Heisenberg Magnet.

A robust spontaneous inversion symmetry breaking is found, reflected in an energy density difference between the two sublattices of tetrahedra, familiar as a starting point of earlier perturbative treatments, and suggest a scenario in which a finite-temperature spin liquid regime gives way to a symmetry-broken state at low temperatures.

Multiloop functional renormalization group approach to quantum spin systems

Renormalization group methods are well-established tools for the (numerical) investigation of the low-energy properties of correlated quantum many-body systems, allowing to capture their

Finite-temperature phase transitions in $S=1/2$ three-dimensional Heisenberg magnets from high-temperature series expansions

By means of high-temperature series expansions we study the singularities of the specific heat ($c_v$) and the magnetic susceptibility ($\chi$) of $S=1/2$ models presenting a phase transition

L-based numerical linked cluster expansion for square lattice models

We introduce a numerical linked cluster expansion for square-lattice models whose building block is an L-shape cluster. This expansion exhibits a similar or better convergence of the bare sums than

Enhanced symmetry-breaking tendencies in the $S=1$ pyrochlore antiferromagnet

We investigate the ground-state properties of the nearest-neighbor S = 1 pyrochlore Heisenberg antiferromagnet using two complementary numerical methods, density-matrix renormalization group (DMRG)

Order, disorder, and monopole confinement in the spin- 12 XXZ model on a pyrochlore tube

We study the ground state and thermodynamic properties of the spin-half XXZ model, with an Ising interaction J z and a transverse exchange interaction J x , on a pyrochlore tube obtained by joining

Thermodynamics of the spin-half square kagome lattice antiferromagnet

Over the last decade, the interest in the spin-1 / 2 Heisenberg antiferromagnet (HAF) on the square-kagome (also called shuriken) lattice has been growing as a model system of quantum magnetism with

Quantum skyrmion lattices in Heisenberg ferromagnets

Skyrmions are topological magnetic textures that can arise in non-centrosymmetric ferromagnetic materials. In most systems experimentally investigated to date, skyrmions emerge as classical objects.



Adapting Planck's route to investigate the thermodynamics of the spin-half pyrochlore Heisenberg antiferromagnet

The spin-half pyrochlore Heisenberg antiferromagnet (PHAF) is one of the most challenging problems in the field of highly frustrated quantum magnetism. Stimulated by the seminal paper of M.~Planck

Finite-Size Scaling of Typicality-Based Estimates

Abstract According to the concept of typicality, an ensemble average can be accurately approximated by an expectation value with respect to a single pure state drawn at random from a high-dimensional

Local entanglement and confinement transitions in the random transverse-field Ising model on the pyrochlore lattice

Author(s): Pardini, T; Menon, A; Hau-Riege, SP; Singh, RRP | Abstract: © 2019 American Physical Society. We use numerical linked cluster expansions (NLC) and exact diagonalization to study

Absence of Superconductivity in the Pure Two-Dimensional Hubbard Model

We study the superconducting pairing correlations in the ground state of the doped Hubbard model -- in its original form without hopping beyond nearest neighbor or other perturbing parameters -- in

Frustrated magnetism and cooperative phase transitions in spinels

The spinel crystal system, AB 2 O 4 , has been fertile ground in studying the effects of magnetic and orbital frustration. The experimental findings, with primary focus on neutron and synchrotron

The possibility of obtaining spin glasses by addition of impurities in an antiferromagnetic insulator is examined. Dipolar interactions are briefly considered but the attention is focussed on

Valence-Bond Crystal and Anisotropic Excitation Spectrum on 3-Dimensionally Frustrated Pyrochlore

The valence-bond crystal is proposed as a ground state of spin-1/2 Heisenberg antiferromagnet on 3-dimensional fully frustrated pyrochlore by the bond-operator theory. This crystal, formed as a set

Exact ground states for a class of antiferromagnetic Heisenberg models with short-range interactions

A special class of Heisenberg spin Hamiltonians with short-range antiferromagnetically signed interactions is described. It is demonstrated via a simple group-theoretic argument that the ground

Ordering and Antiferromagnetism in Ferrites

The octahedral sites in the spinel structure form one of the anomalous lattices in which it is possible to achieve essentially perfect short-range order while maintaining a finite entropy. In such a
