Anomaly Matching in the Symmetry Broken Phase: Domain Walls, CPT, and the Smith Isomorphism
Itamar Hason, Zohar Komargodski, Ryan Thorngren
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes…
Dual Scale Invariance Spontaneous Symmetry Breaking and Turbulence
Itamar Hason
We discuss spontaneous symmetry breaking of dual (space and time) scale invariance in the context of turbulence.
Triviality of Entanglement Entropy in the Galilean Vacuum
Itamar Hason
We study the entanglement entropy of the vacuum in non-relativistic local theories with Galilean or Schrödinger symmetry. We clear some confusion in the literature on the free Schr…
Spontaneous Breaking of Non-Relativistic Scale Symmetry
Igal Arav, Itamar Hason, Yaron Oz
We analyze the mechanism of spontaneous symmetry breaking of scale invariance in Galilean invariant field theories. We show that the existence of a dynamic gapless dilaton mode dep…
Jeans Instability in Superfluids
Itamar Hason, Yaron Oz
We analyze the effect of a gravitational field on the sound modes of superfluids. We derive an instability condition that generalizes the well known Jeans instability of the sound…
