Super-Quantum Mechanics in the Integral Form Formalism

, 2018
We reformulate super-quantum mechanics in the context of inte-gral forms. This framework allows to interpolate between different actionsfor the same theory, connected by different choices of picture changingoperators (PCO).

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Extension of Darken's quadratic formalism to dilute multicomponent solutions

, 1989
Darken's quadratic formalism is extended to multicomponent solutions. Equations are developed for the representation of the integral and partial excess free energies, entropies and enthalpies in dilute multicomponent solutions.

Towards Hamiltonian formalism for string field theory and nonlocality

Journal of High Energy Physics
String field theories exhibit exponential suppression of interactions among the component fields at high energies due to infinite-derivative factors such as e ℓ 2 □ / 2 $$ {e}^{\ell^2\square /2} $$ in the vertices.

The complex Liouville string: Worldsheet boundaries and non-perturbative effects

SciPost Physics
We investigate general observables of the complex Liouville string with worldsheet boundaries. We develop a universal formalism that reduces such observables to ordinary closed string amplitudes without boundaries, applicable to any worldsheet string ...

Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Solution of the Fokker-Planck equation with boundary conditions by Feynman-Kac integration. [PDF]

In this paper, we apply the results about d and d-function perturbations in order to formulate within the Feynman-Kac integration the solution of the forward Fokker-Planck equation subject to Dirichlet or Neumann boundary conditions.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Folded Context Condensation in Path Integral Formalism for Infinite Context Transformers

IEEE Access
In this work, we present a generalized formulation of the Transformer algorithm by reinterpreting its core mechanisms within the framework of Path Integral formalism. In this perspective, the attention mechanism is recast as a process that integrates all

Integrating Formal Methods by Unifying Abstractions [PDF]

, 2004
Integrating formal methods enhances their power as an intellectual tool in modelling and design. This holds regardless of automation, but a fortiori if software tools are conceived in an integrated framework.
