Delayed Coupling Restores Ising Phase Dynamics in Physical Oscillator Networks
Yi Cheng, Liangtao Dai, Mircea R Stan +1
Oscillator-based Ising machines, in which the phases of coupled self-sustaining oscillators evolve toward decreasing an Ising Hamiltonian, are commonly interpreted as physical real…
Computing and Memory Technologies based on Magnetic Skyrmions
Hamed Vakili, Wei Zhou, Chung T Ma +13
Solitonic magnetic excitations such as domain walls and, specifically, skyrmionics enable the possibility of compact, high density, ultrafast,all-electronic, low-energy devices, wh…
Temporal Memory with Magnetic Racetracks
Hamed Vakili, Mohammad Nazmus Sakib, Samiran Ganguly +5
Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning a…
Memristive Learning Cellular Automata: Theory and Applications
Rafailia-Eleni Karamani, Iosif-Angelos Fyrigos, Vasileios Ntinas +6
Memristors are novel non volatile devices that manage to combine storing and processing capabilities in the same physical place.Their nanoscale dimensions and low power consumption…

We present a first of its kind framework which overcomes a major challenge in the design of digital systems that are resilient to reliability failures: achieve desired resilience t…
Computing with Non-equilibrium Ratchets
Mehdi Kabir, Dincer Unluer, Lijun Li +2
Electronic ratchets transduce local spatial asymmetries into directed currents in the absence of a global drain bias, by rectifying temporal signals that reside far from thermal eq…
Graphene Nanoribbons: from chemistry to circuits
Frank Tseng, Dincer Unluer, Mircea R. Stan +1
The Y-chart is a powerful tool for understanding the relationship between various views (behavioral, structural, physical) of a system, at different levels of abstraction, from hig…
Diluted chirality dependence in edge rough graphene nanoribbon field-effect transistors
Frank Tseng, DIncer Unlcer, Katherine Holcomb +2
We investigate the role of various structural nonidealities on the performance of armchair-edge graphene nanoribbon field effect transistors (GNRFETs). Our results show that edge r…
