At sufficiently low temperatures, condensed-matter systems tend to develop order. A notable exception to this behaviour is the case of quantum spin liquids, in which quantum fluctuations prevent a transition to an ordered state down to the lowest temperatures. There have now been tentative observations of such states in some two-dimensional organic compounds, yet quantum spin liquids remain elusive in microscopic two-dimensional models that are relevant to experiments. Here we show, by means of… 
A quantum spin‐liquid in correlated relativistic electrons
In recent years, an increasing number of systems displaying exotic quantum states like unconventional superconductivity, quantum spin‐liquids, or topological states were experimentally found. Here we

Competing Orders in Strongly Correlated Systems -Dirac Materials and Iron-Based Superconductors
In this work we address the collective phenomena appearing in interacting fermion systems due to the competition of distinct orders at the example of Dirac materials and iron-based superconductors.

Experimental observation of the quantum Hall effect and Berry's phase in graphene
TLDR
An experimental investigation of magneto-transport in a high-mobility single layer of graphene observes an unusual half-integer quantum Hall effect for both electron and hole carriers in graphene.
A Mott insulator of fermionic atoms in an optical lattice
TLDR
The formation of a Mott insulator of a repulsively interacting two-component Fermi gas in an optical lattice is reported, identified by three features: a drastic suppression of doubly occupied lattice sites, a strong reduction of the compressibility inferred from the response of double occupancy to an increase in atom number, and the appearance of a gapped mode in the excitation spectrum.
Two-dimensional gas of massless Dirac fermions in graphene
TLDR
This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.
Fluctuating superconductivity in organic molecular metals close to the Mott transition
TLDR
This work argues that a key pseudogap phenomenon—fluctuating superconductivity occurring substantially above the transition temperature—could be induced by the proximity of a Mott-insulating state and finds that a fluctuating regime develops as t/U decreases and the role of Coulomb correlations increases.
Spin correlations in the algebraic spin liquid: Implications for high-Tc superconductors
We propose that underdoped high-T c superconductors are described by an algebraic spin liquid (ASL) at high energies, which undergoes a spin-charge recombination transition at low energies. The spin

TLDR
This work was able to directly measure the compressibility of the quantum gas in the trap using in situ imaging and independent control of external confinement and lattice depth, to demonstrate the potential to model interacting condensed-matter systems using ultracold fermionic atoms.
Short-ranged resonating valence bond physics, quantum dimer models, and Ising gauge theories
Quantum dimer models are believed to capture the essential physics of antiferromagnetic phases dominated by short-ranged valence bond configurations. We show that these models arise as particular

TLDR
Graphene is converted from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator and the spin and charge conductances in these edge states are calculated and the effects of temperature, chemical potential, Rashba coupling, disorder, and symmetry breaking fields are discussed.
