Cumulene Molecular Wire Conductance from First Principles [PDF]
, 2010 We present first principles calculations of current-voltage characteristics (IVC) and conductance of Au(111):S2-cumulene-S2:Au(111) molecular wire junctions with realistic contacts.

Shedding light on moiré excitons: A first-principles perspective [PDF]
Science Advances, 2020 First-principles simulations are performed to shed light on moiré excitons in twisted MoS2/WS2 heterostructures. Moiré superlattices in van der Waals (vdW) heterostructures could trap long-lived interlayer excitons.

Agentic Finance: An Adaptive Inference Framework for Bounded-Rational Investing Agents
EntropyWe propose Adaptive Inference, a portfolio management framework extending Active Inference to non-stationary financial environments. The framework integrates inference, control, and execution under endogenous uncertainty, modeling investment decisions as

Ferroelectric Phase Transitions from First Principles [PDF]
, 1995 An effective Hamiltonian for the ferroelectric transition in $PbTiO_3$ is constructed from first-principles density-functional-theory total-energy and linear-response calculations through the use of a localized, symmetrized basis set of ``lattice Wannier

Discrepancy between experimental and theoretical β-decay rates resolved from first principles [PDF]
Nature Physics, 2019 The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes a neutron into a proton (and vice versa). This decay offers a window to physics beyond the standard model, and is at the heart of microphysical processes in stellar ...

Interatomic Coulombic electron capture from first principles [PDF]
, 2018 Interatomic Coulombic electron capture (ICEC) is an environment-assisted process in which a free electron can efficiently attach to an ion, atom or molecule by transferring the excess energy to a neighboring species. Absolute cross sections are necessary

First-principles calculations on dislocations in MgO
Science and Technology of Advanced MaterialsWhile ceramic materials are widely used in our society, their understanding of the plasticity is not fully understood. MgO is one of the prototypical ceramics, extensively investigated experimentally and theoretically. However, there is still controversy

Extended uncertainty from first principles
Physics Letters B, 2016 A translation operator acting in a space with a diagonal metric is introduced to describe the motion of a particle in a quantum system. We show that the momentum operator and, as a consequence, the uncertainty relation now depend on the metric.

Logos and Logoi in Plotinus. Their nature and Function [PDF]
SCHOLE, 2009 The universe is the result of a production that pertains not to craft, but to nature. This production does not involve either reasoning or concepts, but is the result of a power that acts on matter like an imprint.
