Many Body Scars as a Group Invariant Sector of Hilbert Space
Kiryl Pakrouski, Preethi N. Pallegar, Fedor K. Popov +1
We present a class of Hamiltonians for which a sector of the Hilbert space invariant under a Lie group , which is not a symmetry of , possesses the essential properties o…

Hagedorn Temperature in Large Majorana Quantum Mechanics
Gabriel Gaitan, Igor R. Klebanov, Kiryl Pakrouski +2
We discuss two types of quantum mechanical models that couple large numbers of Majorana fermions and have orthogonal symmetry groups. In models of vector type, only one of the symm…

Majorana Fermion Quantum Mechanics for Higher Rank Tensors
Igor R. Klebanov, Preethi N. Pallegar, Fedor K. Popov
We study quantum mechanical models in which the dynamical degrees of freedom are real fermionic tensors of rank five and higher. They are the non-random counterparts of the Sachdev…
