Holographic Time Crystals vs Penrose

Åsmund Folkestad

In the large limit, no known no-go theorem rules out thermal time crystals that spontaneously break continuous time-translation, unlike in the large volume limit. If thermal ti…

Spoofing Entanglement in Holography

Netta Engelhardt, Åsmund Folkestad, Adam Levine +2

A defining property of Hawking radiation is that states with very low entanglement masquerade as highly mixed states; this property is captured by a quantum computational phenomeno…

Cryptographic Censorship

Netta Engelhardt, Åsmund Folkestad, Adam Levine +2

We formulate and take two large strides towards proving a quantum version of the weak cosmic censorship conjecture. We first prove "Cryptographic Censorship": a theorem showing tha…

Subregion Independence in Gravity

Åsmund Folkestad

In gravity, spacelike separated regions can be dependent on each other due to the constraint equations. In this paper, we give a natural definition of subsystem independence and gr…

The Penrose Inequality as a Constraint on the Low Energy Limit of Quantum Gravity

Åsmund Folkestad

We construct initial data violating the Anti-deSitter Penrose inequality using scalars with various potentials. Since a version of the Penrose inequality can be derived from AdS/CF…

Negative Complexity of Formation: the Compact Dimensions Strike Back

Netta Engelhardt, Åsmund Folkestad

We show that the vacuum-subtracted maximal volume, the proposed holographic dual to complexity of formation, can be negative when contributions from compact directions are included…

Holography Abhors Visible Trapped Surfaces

Netta Engelhardt, Åsmund Folkestad

We prove that consistency of the holographic dictionary implies a hallmark prediction of the weak cosmic censorship conjecture: that in classical gravity, trapped surfaces lie behi…

Coupling Constant Corrections in a Holographic Model of Heavy Ion Collisions with Nonzero Baryon Number Density

Åsmund Folkestad, Sašo Grozdanov, Krishna Rajagopal +1

Sufficiently energetic collisions of heavy ions result in the formation of a droplet of a strongly coupled liquid state of QCD matter known as quark-gluon plasma. By using gauge-gr…
