Holographic Lattices Give the Graviton a Mass
Mike Blake, David Tong, David Vegh
We discuss the DC conductivity of holographic theories with translational invariance broken by a background lattice. We show that the presence of the lattice induces an effective m…
Holographic Dual of the Lowest Landau Level
Mike Blake, Stefano Bolognesi, David Tong +1
We describe the lowest Landau level of a quantum electron star in AdS4. In the presence of a suitably strong magnetic field, the dynamics of fermions in the bulk is effectively red…
TF1 Snowmass Report: Quantum gravity, string theory, and black holes
Daniel Harlow, Shamit Kachru, Juan Maldacena +35
We give an overview of the field of quantum gravity, string theory and black holes summarizing various white papers in this subject that were submitted as part of the Snowmass proc…
Thermal diffusivity and chaos in metals without quasiparticles
Mike Blake, Richard A. Davison, Subir Sachdev
We study the thermal diffusivity in models of metals without quasiparticle excitations (`strange metals'). The many-body quantum chaos and transport properties of such metals…
Horizon constraints on holographic Green's functions
Mike Blake, Richard A. Davison, David Vegh
We explore a new class of general properties of thermal holographic Green's functions that can be deduced from the near-horizon behaviour of classical perturbations in asymptotical…
The Page curve from the entanglement membrane
Mike Blake, Anthony P. Thompson
We study entanglement dynamics in toy models of black hole information built out of chaotic many-body quantum systems, by utilising a coarse-grained description of entanglement dyn…
Snowmass White Paper: New ideas for many-body quantum systems from string theory and black holes
Mike Blake, Yingfei Gu, Sean A. Hartnoll +5
During the last two decades many new insights into the dynamics of strongly coupled quantum many-body systems have been obtained using gauge/gravity duality, with black holes often…
Many-body chaos and energy dynamics in holography
Mike Blake, Richard A. Davison, Sašo Grozdanov +1
Recent developments have indicated that in addition to out-of-time ordered correlation functions (OTOCs), quantum chaos also has a sharp manifestation in the thermal energy density…
Universal Diffusion in Incoherent Black Holes
Mike Blake
We study charge and energy diffusion in simple holographic theories with broken translational symmetry. We find that when the effects of momentum relaxation are very strong the dif…
Universal Resistivity from Holographic Massive Gravity
Mike Blake, David Tong
Massive gravity provides a holographic model for theories exhibiting momentum dissipation. We provide an analytic expression for the DC conductivity. The result is universal, depen…
Dissipative hydrodynamic actions and horizon symmetries in gravity
Mike Blake, Arpit Das, Richard A. Davison
We give a prescription to compute a dissipative action describing the large-scale thermal stress tensor dynamics of a holographic quantum field theory dual to AdS gravity, in t…
Chaos and pole-skipping in a simply spinning plasma
Markus A. G. Amano, Mike Blake, Casey Cartwright +2
We study the relationship between many-body quantum chaos and energy dynamics in holographic quantum field theory states dual to the simply-spinning Myers-Perry-AdS black hole.…
Momentum relaxation from the fluid/gravity correspondence
Mike Blake
We provide a hydrodynamical description of a holographic theory with broken translation invariance. We use the fluid/gravity correspondence to systematically obtain both the consti…
On systems of maximal quantum chaos
Mike Blake, Hong Liu
A remarkable feature of chaos in many-body quantum systems is the existence of a bound on the quantum Lyapunov exponent. An important question is to understand what is special abou…
Quantum circuits with classically simulable operator scrambling
Mike Blake, Noah Linden
We introduce a new family of quantum circuits for which the scrambling of a subspace of non-local operators is classically simulable. We call these circuits `super-Clifford circuit…
Large Nc Equivalence and Baryons
Mike Blake, Aleksey Cherman
In the large Nc limit, gauge theories with different gauge groups and matter content sometimes turn out to be `large Nc equivalent', in the sense of having a set of coincident corr…
Magnetothermoelectric Response from Holography
Mike Blake, Aristomenis Donos, Nakarin Lohitsiri
In this note we study the effects of a magnetic field on transport using holographic models with broken translational invariance. We show that, after carefully subtracting off non-…
Universal Charge Diffusion and the Butterfly Effect
Mike Blake
We study charge diffusion in holographic scaling theories with a particle-hole symmetry. We show that these theories have a universal regime in which the diffusion constant is give…
Chaos and pole-skipping in rotating black holes
Mike Blake, Richard A. Davison
We study the connection between many-body quantum chaos and energy dynamics for the holographic theory dual to the Kerr-AdS black hole. In particular, we determine a partial differ…
Diffusion and Chaos from near AdS horizons
Mike Blake, Aristomenis Donos
We calculate the thermal diffusivity and butterfly velocity in holographic models that flow to AdS fixed points in the infra-red. We show that…
Quantum Critical Transport and the Hall Angle
Mike Blake, Aristomenis Donos
In this letter we study the Hall conductivity in holographic models where translational invariance is broken by a lattice. We show that generic holographic theories will display a…
Fast Scrambling in Classically Simulable Quantum Circuits
Mike Blake, Noah Linden, Anthony P. Thompson
We study operator scrambling in quantum circuits built from `super-Clifford' gates. For such circuits it was established in arXiv:2002.12824 that the time evolution of operator ent…
Islands, Double Holography, and the Entanglement Membrane
Hanzhi Jiang, Mike Blake, Anthony P. Thompson
The quantum extremal island rule allows us to compute the Page curves of Hawking radiation in semi-classical gravity. In this work, we study the connection between these calculatio…
