Pressure and Temperature Sensors Using Two Spin Crossover Materials

open access: yesSensors, 2016
The possibility of a new design concept for dual spin crossover based sensors for concomitant detection of both temperature and pressure is presented. It is conjectured from numerical results obtained by mean field approximation applied to a Ising-like ...

Probing the BCS-BEC crossover with persistent currents

open access: yesPhysical Review Research, 2021
We study the persistent currents of an attractive Fermi gas confined in a tightly confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover. At weak attractions, on the Bardeen-Cooper-Schrieffer (BCS) side, fermions

Weak localization and dimensional crossover in carbon nanotube systems [PDF]

open access: yesThe European Physical Journal B, 2012
We investigate the effects of magnetic and electric fields on electron wavefunction interactions in single walled carbon nanotube bundles. The magnetoresistance measurements performed at 4.2K and the dependence of the data upon the electric field, obtained by varying the bias current through the samples, reveal good agreement with weak localization ...

Weak (anti)localization in tubular semiconductor nanowires with spin-orbit coupling [PDF]

open access: yes, 2016
We compute analytically the weak (anti)localization correction to the Drude conductivity for electrons in tubular semiconductor systems of zinc blende type.

Giant superconducting fluctuations in the compensated semimetal FeSe at the BCS–BEC crossover

open access: yesNature Communications, 2016
The crossover between the weak-coupling limit and strong-coupling limit provides important information for quantum bound states of interacting fermions. Here, Kasahara et al.

Correlating Disorder Microstructure and Magnetotransport of Carbon Nanowalls

open access: yesApplied Sciences, 2023
The carbon nanowalls (CNWs) grown by Plasma-Enhanced CVD reveal differences in the magnetotransport properties depending on the synthesis parameters. In this paper, we report the influence of the deposition temperature, which produces variations of the ...

Dynamic structure factor of the magnetized one-component plasma: Crossover from weak to strong coupling

open access: yesPhysical Review Research, 2022
Plasmas in strong magnetic fields have been mainly studied in two distinct limiting cases—that of weak and strong nonideality with very different physical properties.

Vertical nanoscale strain-induced electronic localization in epitaxial La2/3Sr1/3MnO3 films with ZrO2 nanopillar inclusions

open access: yesNano Convergence, 2023
Unusual electrical transport properties associated with weak or strong localization are sometimes found in disordered electronic materials. Here, we report experimental observation of a crossover of electronic behavior from weak localization to enhanced ...

Weak Localization in Metallic Granular Media

open access: yes, 2006
We investigate the interference correction to the conductivity of a medium consisting of metallic grains connected by tunnel junctions. Tunneling conductance between the grains, $e^2g_{\rm T}/\pi\hbar$, is assumed to be large, $g_{\rm T}\gg 1$.

A Remark on Supersymmetric Bubbles and Spectrum Crossover

open access: yes, 2012
Using an exact expression for the domain wall tension in a supersymmetric model we show that a spectrum crossover takes place in passing from weak to strong coupling.
