Slow Nonthermalizing Dynamics in a Quantum Spin Glass
Louk Rademaker, Dmitry A. Abanin
Spin glasses and many-body localization (MBL) are prime examples of ergodicity breaking, yet their physical origin is quite different: the former phase arises due to rugged classic…
Stability and Absence of a Tower of States in Ferrimagnets
Louk Rademaker, Aron Beekman, Jasper van Wezel
Antiferromagnets and ferromagnets are archetypes of the two distinct (type-A and type-B) ways of spontaneously breaking a continuous symmetry. Although type-B Nambu--Goldstone mode…
Exact Ground State of Lieb-Mattis Hamiltonian as a Superposition of Néel states
Louk Rademaker
We show that the exact ground state of the Lieb-Mattis Hamiltonian is an equal-weight superposition of all possible classical Néel states, and provide an exact formulation of this…
An Introduction to Spontaneous Symmetry Breaking
Aron J. Beekman, Louk Rademaker, Jasper van Wezel
Perhaps the most important aspect of symmetry in physics is the idea that a state does not need to have the same symmetries as the theory that describes it. This phenomenon is know…
Charge Smoothening and Band Flattening due to Hartree corrections in Twisted Bilayer Graphene
Louk Rademaker, Dmitry A. Abanin, Paula Mellado
Doping twisted bilayer graphene away from charge neutrality leads to an enormous buildup of charge inhomogeneities within each Moiré unit cell. Here we show, using unbiased real-sp…
Construction of Many-Body Eigenstates with Displacement Transformations
Miguel Ortuño, Andres M. Somoza, Louk Rademaker
Many-body eigenstates beyond the gaussian approximation can be constructed in terms of local integrals of motion (IOM), although their actual computation has been until now a daunt…
