Quantum Many-Body Physics & Simulation: State of the Field (October 2026)

Covers thermalization and its breakdown, many-body localization, quantum many-body scars, discrete time crystals and analog and digital quantum simulators of many-body dynamics. The key takeaway: the theory of localization and scarring is mature, but the central experimental question has shifted to whether quantum devices can reach dynamics that classical methods cannot reproduce, and that question remains contested.

Sample findings

  • The eigenstate thermalization hypothesis states that individual energy eigenstates of a generic closed quantum system already reproduce thermal expectation values of local observables.
  • Exact diagonalization of a random-field Heisenberg spin chain resolved an energy-dependent many-body localization transition for system sizes up to L = 22 spins.
