First-Order Insulator-to-Metal Mott Transition in the Paramagnetic 3D System GaTa4Se8 [PDF]

, 2014
The nature of the Mott transition in the absence of any symmetry braking remains a matter of debate. We study the correlation-driven insulator-to-metal transition in the prototypical 3D Mott system GaTa4Se8, as a function of temperature and applied ...

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.

Trapping Dynamics with Gated Traps: Stochastic Resonance-Like Phenomenon

, 2000
We present a simple one-dimensional trapping model prompted by the problem of ion current across biological membranes. The trap is modeled mimicking the ionic channel membrane behaviour. Such voltage-sensitive channels are open or closed depending on the

On the Influence of Noise on the Critical and Oscillatory Behavior of a Predator-Prey Model: Coherent Stochastic Resonance at the Proper Frequency [PDF]

, 2000
Noise induced changes in the critical and oscillatory behavior of a Prey-Predator system are studied using power spectrum density and Spectral Amplification Factor (SAF) analysis.

Thermoelectric Processes of Quantum Normal‐Superconductor Interfaces

Annalen der Physik, Volume 537, Issue 11, November 2025.
Recent advances on using mesoscopic normal‐superconductor junctions for the thermoelectric effect is reviewed. A theoretical framework is presented for multiterminal configurations exploiting properties characterised by the interplay of the system reduced dimensionality and superconducting correlations.

Aspects of quantum information in finite density field theory

Journal of High Energy Physics, 2021
We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero chemical potential, and work in 1 + 1 space-time dimensions.

Magnetic excitations of perovskite rare-earth nickelates: RNiO$_3$ [PDF]

, 2015
The perovskite nickelates RNiO$_3$ (R: rare-earth) have been studied as potential multiferroic compounds. A certain degree of charge disproportionation in the Ni ions has been confirmed by high resolution synchrotron power diffraction: instead of the ...

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

Symmetry enhancement interpolation, non-commutativity and Double Field Theory

Journal of High Energy Physics, 2019
We present a moduli dependent target space effective field theory action for (truncated) heterotic string toroidal compactifications. When moving continuously along moduli space, the stringy gauge symmetry enhancement-breaking effects, which occur at ...

Silicon nitride polarisation beam splitters: a review

IET Optoelectronics, 2020
In this work, the authors review different design setups of polarisation beam splitters (PBSs) developed in Si3N4 platforms. They analyse different approaches based on directional couplers and interferometers.
