Using a low\u2013energy massive Dirac model combined with linear resp Alipourzadeh onse theory, we analyze how spin\u2013orbit coupling, inversion\u2013symmetry breaking, optical driving, and finite temperature jointly influence the Hall conductivities. At zero temperature, the spin\u2013Hall and valley\u2013Hall conductivities exhibit step\u2013like plateau features, reflecting the underlying topological character of the massive Dirac bands. The off-resonant circularly polarized light effectively renormalizes the Dirac mass and modifies the band structure, enabling controllable transitions between distinct Hall response regimes. While the spin\u2013Hall effect arises intrinsically from strong spin\u2013orbit coupling, the valley\u2013Hall effect appears only when inversion symmetry is broken by a staggered sublattice potential, with characteristic critical points associated with gap closing. At finite temperatures, thermal broadening smooths these plateau-like features into continuous Fermi energy dependent responses and reduces the magnitude of both Hall effects. Nevertheless, the corresponding topological signatures remain robust at low and moderate temperatures, particularly near charge neutrality. We further show that circularly polarized light alone cannot generate a finite valley\u2013Hall response at finite temperatures without inversion symmetry breaking. These results demonstrate that the combined action of optical driving, electric field control, and thermal effects provides an effective route to manipulate spin and valley transport in jacutingaite, highlighting its potential for tunable spintronic and valleytronic applications.\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/ae49cf","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T22:53:37Z","timestamp":1771973617000},"page":"095703","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Spin\/valley effects and finite\u2013temperature effects on the Hall conductivity of jacutingaite"],"prefix":"10.1088","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9152-3840","authenticated-orcid":true,"given":"Do","family":"Muoi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2026,3,5]]},"reference":[{"key":"cmae49cfbib1","doi-asserted-by":"publisher","first-page":"6","DOI":"10.1134\/S1063776124601022","type":"journal-article","article-title":"Effect of temperature and magnetic field on the resistivity of a quasi two dimensional in GaP\/AlP\/GaP layered structures","volume":"138","author":"Muoi","year":"2024","journal-title":"J.
