Moving the CFT into the bulk with TT¯$$ T\overline{T} $$
A bstractRecent work by Zamolodchikov and others has uncovered a solvable irrelevant deformation of general 2D CFTs, defined by turning on the dimension 4 operator TT¯$$ T\overline{T} $$,the product… Expand

A refinement of entanglement entropy and the number of degrees of freedom
A bstractWe introduce a “renormalized entanglement entropy” which is intrinsically UV finite and is most sensitive to the degrees of freedom at the scale of the size R of the entangled region. We… Expand

Semi-local quantum liquids
A bstractGauge/gravity duality applied to strongly interacting systems at finite density predicts a universal intermediate energy phase to which we refer as a semi-local quantum liquid. Such a phase… Expand

Quantum phase transitions in semilocal quantum liquids
We consider several types of quantum critical phenomena from finite-density gauge-gravity duality which to different degrees lie outside the Landau-Ginsburg-Wilson paradigm. These include: (i) a… Expand

Monopole operators in U(1) Chern-Simons-matter theories
A bstractWe study monopole operators at the infrared fixed points of U(1) Chern-Simons-matter theories (QED3, scalar QED3, N=1$$ \mathcal{N}=1 $$ SQED3, and N=2$$ \mathcal{N}=2 $$ SQED3) with N… Expand

Entanglement growth after a global quench in free scalar field theory
A bstractWe compute the entanglement and Rényi entropy growth after a global quench in various dimensions in free scalar field theory. We study two types of quenches: a boundary state quench and a… Expand

Bit Threads and the Membrane Theory of Entanglement Dynamics
Recently, an effective {\it membrane theory} was proposed that describes the ``hydrodynamic'' regime of the entanglement dynamics for general chaotic systems. Motivated by the new {\it bit threads}… Expand

Pole skipping away from maximal chaos
Pole skipping is a recently discovered subtle effect in the thermal energy density retarded two point function at a special point in the complex ( ω, p ) planes. We propose that pole skipping is… Expand

Monopole operators from the 4 − ϵ expansion
A bstractThree-dimensional quantum electrodynamics with N charged fermions contains monopole operators that have been studied perturbatively at large N . Here, we initiate the study of these monopole… Expand

Scaling dimensions of monopole operators in the ℂℙNb−1$$ \mathbb{C}{\mathrm{\mathbb{P}}}^{N_b-1} $$ theory in 2 + 1 dimensions
A bstractWe study monopole operators at the conformal critical point of the ℂℙNb−1$$ \mathbb{C}{\mathrm{\mathbb{P}}}^{N_b-1} $$ theory in 2+1 spacetime dimensions. Using the state-operator… Expand
