Entropy maximization and weak Gibbsianity of quasi-free fermionic states

Abstract In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invariant states with a fixed two-point function and suggested that the maximizer is unique. In s...

Detection of spiking motifs of arbitrary length in neural activity using bounded synaptic delays

In the context of spiking neural networks, the temporal coding hypothesis is increasingly preferred over the rate coding hypothesis due to its advantages in processing speed and energy efficiency. In temporal coding, synaptic delays are crucial for processing signals with precise...

High‐Detectivity InGaAs/GaAsP Superlattice PIN Photodetector with a Thin Absorber on GaAs substrate for 1100 nm Applications

ABSTRACT III‐V materials exhibit superior optoelectronic properties compared to conventional semiconductors, making them ideal for short‐wavelength infrared (SWIR) photodetectors. These devices are in demand for applications such as telecommunications, LiDAR, and biomedical engin...
