Emergent topological structure in spontaneous brain-organoid activity
Eve Bodnia, Margaux Basart, Sofie Hai +5
Neural activity is widely held to organize on low-dimensional structure embedded in a high-dimensional state space. Persistent homology reads such structure directly from the patte…
Tunable Bands in 1D Fractional Quantum Media
Brenden R. Guyette, Joshua M. Lewis, Lincoln D. Carr
Fractional calculus has become an essential framework in geophysics, optics, and biological systems to capture long-range correlations and anomalous transport. In this article, we…
Integrability of Goldilocks quantum cellular automata
Logan E. Hillberry, Lorenzo Piroli, Eric Vernier +3
Goldilocks quantum cellular automata (QCA) have been simulated on quantum hardware and produce emergent small-world correlation networks. In Goldilocks QCA, a single-qubit unitary…
Propagation of Spin Waves in Doubly Periodic Magnonic Crystals
Adam G. Whitney, Joshua M. Lewis, Justin Dickovick +3
Towards the development of strategies for tailoring spin-wave band gaps in magnonic crystals, this work examines the band gap properties in a one-dimensional magnonic crystal with…
Lévy Light Cones and Critical Causality in Fractional Multiscale Quantum Ising Models
Joshua M Lewis, Zhexuan Gong, Lincoln D Carr
We study causality and criticality in a one-dimensional fractional multiscale transverse-field Ising model, where fractional derivatives generate long range interactions beyond the…
Rotational decoherence dynamics in ultracold molecules induced by a tunable spin environment: The Central Rotor Model
Timur V. Tscherbul, Lincoln D. Carr
We show that quantum rotational wavepacket dynamics in molecules can be described by a new system-environment model, which consists of a rotational subsystem coupled to a magnetica…
