The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

The Role of Current Mismatch on Reverse‐Bias Stability of Monolithic Perovskite/Silicon Tandem Solar Cells

open access: yesEcoEnergy, EarlyView.
Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Rhythms in longitudinal thalamic recordings are linked to seizure risk

open access: yesEpilepsia, EarlyView.
Abstract Objective Seizure unpredictability remains a major clinical challenge for people with epilepsy. Previous works have shown that seizure risk is associated with circadian and multi‐day cycles in both brain and physiological signals. However, it remains unclear whether neural activity from deep brain structures such as the anterior nucleus of the
