Granovskii-Zhedanov Scars of XYZ Models: Modern Algebraic Perspectives and Realization in Higher Dimensional Lattices
Dhiman Bhowmick, Wen Wei Ho
In a work by Granovskii and Zhedanov, a surprising family of scar states exhibiting zero entanglement was discovered in the XYZ spin chain, remarkably, nearly three decades before…

Scalable tests of quantum contextuality from stabilizer-testing nonlocal games
Wanbing Zhao, H. W. Shawn Liew, Wen Wei Ho +2
Soon after the dawn of quantum error correction, DiVincenzo and Peres observed that stabilizer codewords could give rise to simple proofs of quantumness via contextuality. This dis…

Asymmetric decay of quantum many-body scars in XYZ quantum spin chains
Dhiman Bhowmick, Vir B. Bulchandani, Wen Wei Ho
Quantum many-body scars are atypical energy eigenstates of chaotic quantum many-body systems that prevent certain special non-equilibrium initial conditions from thermalizing. We p…
