Abstract: A bstractIt is believed that any classical gauge symmetry gives rise to an L∞ algebra. Based on the recently realized relation between classical W$$ \mathcal{W} $$ algebras and L∞ algebras, we analyze how this generalizes… read more here.

Abstract: We consider the group structure of quantum cellular automata (QCA) modulo circuits and show that it is abelian even without assuming the presence of ancillas, at least for most reasonable choices of control space; this… read more here.

DOI: 10.1103/physreva.104.012605
Abstract: As larger, higher-quality quantum devices are built and demonstrated in quantum information applications, such as quantum computation and quantum communication, the need for high-quality quantum memories to store quantum states becomes ever more pressing. Future… read more here.

DOI: 10.1103/physrevb.102.224424
Abstract: SrCuTe$_2$O$_6$ consists of a 3-dimensional arrangement of spin-$\frac{1}{2}$ Cu$^{2+}$ ions. The 1st, 2nd and 3rd neighbor interactions respectively couple Cu$^{2+}$ moments into a network of isolated triangles, a highly frustrated hyperkagome lattice consisting of corner… read more here.
