Hilbert Space Fragmentation and Commutant Algebras
Sanjay Moudgalya, Olexei I. Motrunich
We study the phenomenon of Hilbert space fragmentation in isolated Hamiltonian and Floquet quantum systems using the language of commutant algebras, the algebra of all operators th…

Infinite randomness with continuously varying critical exponents in the random XYZ spin chain
Brenden Roberts, Olexei I. Motrunich
We study the antiferromagnetic XYZ spin chain with quenched bond randomness, focusing on a critical line between localized Ising magnetic phases. A previous calculation using the s…
