Fig. 1 Magnetotransport on a quasi-two-dimensional Fermi surface. a Electrons slide around orbits perpendicular to B until a collision randomises their momentum, drawn as a faint chord. Trail length tracks ωcτ. Shading shows the scattering rate, strongest at the antinodes. Warming raises it everywhere by the same factor, so trails shorten and the magnetoresistance falls, obeying Kohler's rule. b Inset: real-space path of the ringed electron. c Inset: magnetoresistance for B ∥ c from the Boltzmann equation with the same scattering rates, on log–log axes. It grows as B² until electrons get a fraction of the way around an orbit, then saturates. ωcτ is exaggerated roughly twentyfold so the orbits read clearly. Drag the surface to tilt the field.

Universal correlation between H-linear magnetoresistance and T-linear resistivity in high-temperature superconductors

In three hole-doped cuprate families, the field-linear magnetoresistance correlates universally with the temperature-linear resistivity, contrary to Boltzmann theory, suggesting that superconductivity is governed by the concentration of strange-metallic carriers.

Transport evidence for decoupled nematic and magnetic criticality in iron chalcogenides

Under pressure, the resistivity of FeSe1−xSx beyond its nematic critical point splits into two components, one suppressed by pressure and one growing towards the magnetic phase, hinting that nematic and magnetic critical fluctuations are decoupled.

I study correlated electron systems, materials where strong interactions between electrons produce collective behaviour that current theory struggles to explain: unconventional superconductivity, magnetism and exotic metallic states.
