Bosonization and Strongly Correlated Systems
This volume provides a detailed account of bosonization. The first part of the book examines the technical aspects of bosonization including one-dimensional fermions, the Gaussian model, the…

Quantum field theory in condensed matter physics
This book is a course in modern quantum field theory as seen through the eyes of a theorist working in condensed matter physics. It contains a gentle introduction to the subject and can therefore be…

Experimental realization of a 2D fractional quantum spin liquid.
TLDR
The dynamic correlations show a highly dispersive continuum of excited states, characteristic of the resonating valence bond state, arising from pairs of S = 1/2 spinons.

Non-perturbative methodologies for low-dimensional strongly-correlated systems: From non-Abelian bosonization to truncated spectrum methods.
TLDR
A comprehensive review of non-Abelian bosonization and recent work on the development of renormalization groups that alleviate the effects of truncating the spectrum for the numerical study of systems in one and two dimensions are reviewed.

Long-range magnetic ordering in Na 2 IrO 3
We report a combined experimental and theoretical investigation of the magnetic structure of the honeycomb-lattice magnet Na${}_{2}$IrO${}_{3}$, a candidate for a realization of a gapless spin…

Two-dimensional superconducting fluctuations in stripe-ordered La1.875Ba0.125CuO4.
TLDR
It appears that the stripe order in La(2-x)Ba(x)CuO(4) frustrates three-dimensional superconducting phase order, but is fully compatible with 2D superconductivity and an enhanced T(c).

Testing the validity of the strong spin-orbit-coupling limit for octahedrally coordinated iridate compounds in a model system Sr3CuIrO6.
TLDR
Effective Hamiltonian and ab inito quantum chemistry calculations find a strikingly large noncubic crystal field splitting comparable to the spin-orbit coupling, which results in a strong mixing of the j(eff)=1/2 and j(EFF)=3/2 states and modifies the isotropic wave functions on which many theoretical models are based.

Quantum critical fluctuations in layered YFe2Al10
TLDR
High precision measurements of the magnetic susceptibility, specific heat, and electrical resistivity in the layered compound YFe2Al10 demonstrate robust field-temperature scaling, evidence that this system is naturally poised without tuning on the verge of ferromagnetic order that occurs exactly at T = 0.

How should we interpret the two transport relaxation times in the cuprates
We observe that the appearance of two transport relaxation times in the various transport coefficients of cuprate metals may be understood in terms of scattering processes that discriminate between…
