Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

The paradigmatic example of deconfined quantum criticality is the Neel to valence bond
solid phase transition. The continuum description of this transition is the N= 2 case of the …

The theory of deconfined quantum critical (DQC) points describes phase transitions at
absolute temperature T= 0 outside the standard paradigm, predicting continuous …

Numerical studies of the transition between Néel and valence bond solid phases in two-
dimensional quantum antiferromagnets give strong evidence for the remarkable scenario of …

In recent work, we argued that a particular algebraic spin liquid (ASL) may be the ground
state of the S= 1/2 kagome lattice Heisenberg antiferromagnet. Furthermore, this state, which …

Over the past two decades, the enigma of the deconfined quantum critical point (DQCP) has
attracted broad attention across the condensed matter, quantum field theory, and high …

A quantum spin-liquid phase is an intriguing possibility for a system of strongly interacting
magnetic units in which the usual magnetically ordered ground state is avoided owing to …

We show numerically that the “deconfined” quantum critical point between the Néel
antiferromagnet and the columnar valence-bond solid, for a square lattice of spin 1/2, has an …
