Associative Memory for Quantum Entangled States
Qiyuan Hu, Kartiek Agarwal, Ivar Martin
We generalize the canonical Hopfield model of associative memory, which stores classical states of individual spins, to store entangled quantum states. The construction is based on…
Moiré-induced altermagnetism from nonmagnetic constituents
Jingtian Shi, Maxim Khodas, Ivar Martin
We propose a mechanism for nonmagnetic materials to develop altermagnetic order by moiré interference with nonmagnetic substrate, which is driven by structural relaxation and spont…
Symmetry-protected cubic-touching topological surface bands with tunable singularities
Jingtian Shi, Taylor L. Hughes, Ivar Martin
We propose a class of topological surface bands in three-dimensional topological crystalline insulators that have symmetry-protected cubic-order band touching. Within the symmetry…
Quantum-stabilized patterns in a vector Hopfield network
Richard D. Barney, Sharba Bhattacharjee, Victor Galitski +2
We introduce the quantum vector Hopfield network, in which patterns are formed by orientations of quantum vector spins; quantum dynamics arise intrinsically from the non-commutativ…
Spontaneous Twirls and Structural Frustration in Moiré Materials
Jingtian Shi, Gaurav Chaudhary, Allan H. MacDonald +1
Structural twirls form spontaneously in the domain wall networks of some moiré materials. We show that in heterobilayers, neighboring twirl chiralities tend to anti-align, forming…
Accuracy and capacity of Modern Hopfield networks with synaptic noise
Sharba Bhattacharjee, Ivar Martin
We study the retrieval accuracy and capacity of modern Hopfield networks of with two-state (Ising) spins interacting via modified Hebbian -spin interactions. In particular, we c…
