abstract
Continuous phase transitions in equilibrium statistical mechanics were successfully described 50 years ago with the development of the renormalization group framework. This framework was initially developed in the context of phase transitions whose universal properties are captured by the long wavelength (and long time) fluctuations of a Landau order parameter field. Subsequent developments include a straightforward generalization to a class of $T = 0$ phase transitions driven by quantum fluctuations. In the last 2 decades it has become clear that there is a vast landscape of quantum phase transitions where the physics is not always usefully (or sometimes cannot be) formulated in terms of fluctuations of a Landau order parameter field. A wide class of such phase transitions - dubbed deconfined quantum critical points - involve the emergence of fractionalized degrees of freedom coupled to emergent gauge fields. Here I review some salient aspects of these deconfined critical points.

Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Near dimensional reduction in Cu2(OH)3Br, THz modes show m2/m1 at the golden ratio and higher peaks consistent with the E8 massive spectrum of a perturbed transverse-field Ising chain.

Emergent relativistic symmetry from interacting fermions on the honeycomb bilayer
QMC shows the continuous semimetal-insulator transition of interacting spinless fermions on the honeycomb bilayer belongs to the 2+1D Gross-Neveu-Ising class with eight Dirac flavors, confirming emergent relativistic ...

Measurement Induced Asymmetric Entanglement in a Deconfined Quantum Critical Ground State
Weak Z-type measurements on a 1D deconfined quantum critical analog cause asymmetric entanglement restructuring, with the (↓↓) outcome increasing entanglement for K<K_c and decreasing it for K>K_c, suggesting a weak f...

Bootstrapping the Simplest Deconfined Quantum Critical Point
Conformal bootstrap bounds for U(1)-charged scalars in 3d are saturated by the CP^2 model's large-N and lattice predictions, suggesting the CP^2 deconfined quantum critical point is a conformal field theory.
