Beyond Impedance Additivity: A Systematic Nonlinear Perspective on Memristor Associations
Luiz A. Meneghetti, Leonardo K. Castelano, Antônio Sérgio dos Santos +5
We investigate the validity of the superposition principle and impedance additivity in AC circuits containing a memristive device connected in series with a resistor, capacitor, or…
A topological field-effect memristor
Manuel Meyer, Selena Barragan, Sergey Krishtopenko +13
Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing…
2D Canonical Approach for Beating the Boltzmann Tyranny Using Memory
Rafael Schio Wengenroth Silva, Soumen Pradhan, Fabian Hartmann +4
The 60 mVdecade subthreshold limit at room temperature, coined as the Boltzmann tyranny, remains a fundamental obstacle to the continued down-scaling of conventional transistors…
Microscopic Modeling of Polarization Dynamics in Leaky Dielectrics: Insights into Ferroelectric-Like Behavior
Igor Ricardo Filgueira e Silva, Ovidiu Lipan, Fabian Hartmann +2
Based on a microscopic model of nonequilibrium carrier generation in a leaky dielectric, we analytically derive hysteresis loops for the dielectric response of non-polar, non-ferro…
Bound States in Continuum via Singular Transfer Matrices
Ovidiu-Zeno Lipan, Aldo De Sabata
In recent years, bound states in continuum (BICs) have gained significant value for practitioners in both theoretical and applied photonics. This paper focuses on devices that util…
Accuracy Bottlenecks in Impedance Spectroscopy due to Transient Effects
Victor Lopez-Richard, Soumen Pradhan, Leonardo K. Castelano +4
Impedance spectroscopy is vital for material characterization and assessing electrochemical device performance. It provides real-time analysis of dynamic processes such as electrod…
Closed-form analytical solution for the transfer matrix based on Pendry-MacKinnon discrete Maxwell's equations
Ovidiu-Zeno Lipan, Aldo De Sabata
Pendry and MacKinnon meaningful discretization of Maxwell's equations was put forward specifically as part of a finite-element numerical algorithm. By contrast with a numerical app…
Beyond equivalent circuit representations in nonlinear systems with inherent memory
V. Lopez-Richard, S. Pradhan, R. S. Wengenroth Silva +4
Basic multimode impedance analysis grounded in the availability of nonequilibrium charge carriers and their retarded path towards equilibrium is used to access the inadequacy of eq…
Tuning the conductance topology in solids
Victor Lopez-Richard, Rafael Schio Wengenroth Silva, Ovidiu Lipan +1
The inertia of trapping and detrapping of nonequilibrium charge carriers affects the electrochemical and transport properties of both bulk and nanoscopic structures in a very pecul…
Splitting Nodes and Linking Channels: A Method for Assembling Biocircuits from Stochastic Elementary Units
Cameron Ferwerda, Ovidiu Lipan
Akin to electric circuits, we construct biocircuits that are manipulated by cutting and assembling channels through which stochastic information flows. This diagrammatic manipulati…
Signal Propagation in Nonlinear Stochastic Gene Regulatory Networks
Sever Achimescu, Ovidiu Lipan
The structure of a stochastic nonlinear gene regulatory network is uncovered by studying its response to input signal generators. Four applications are studied in detail: a nonline…
The use of oscillatory signals in the study of genetic networks
Ovidiu Lipan, Wing H. Wong
The structure of a genetic network is uncovered by studying its response to external stimuli (input signals). We present a theory of propagation of an input signal through a linear…
Baxter T-Q Equation for Shape Invariant Potentials. The Finite-Gap Potentials Case
Ovidiu Lipan, Constantin Rasinariu
The Darboux transformation applied recurrently on a Schroedinger operator generates what is called a {\em dressing chain}, or from a different point of view, a set of supersymmetri…
Bandwidths Statistics from the Eigenvalue Moments for Harper-Hofstadter Problem
O. Lipan
I propose a method for studying the product of bandwidths for the Harper-Hofstader model. This method requires knowledge of the moments of the midband energies. I conjectured a gen…
