Measurements of quantum materials
Interpret complementary probes of quantum matter through their response functions, resolution, selection rules, and distinct sensitivity to bulk and surface properties.
- 01
Four-probe resistivity and contact effects
Extract a material resistivity while testing geometry, voltage loading, offsets, and current heating.
32 min - 02
Hall measurements and multicarrier ambiguity
Fix a transverse-voltage convention and show why a Hall density is conditional on a carrier model.
32 min - 03
Quantum oscillations and Fermi-surface areas
Infer an extremal orbit area while keeping thermal, disorder, spin, and phase ambiguities explicit.
32 min - 04
Angle-resolved photoemission and spectral functions
Relate photoelectron kinematics to occupied spectral weight without treating intensity as an unfiltered band picture.
32 min - 05
Scanning tunneling spectroscopy and local density of states
Interpret a local tunneling spectrum while tracking the tip, barrier, feedback, and thermal kernel.
32 min - 06
Inelastic neutron scattering and dynamical structure factors
Define energy transfer and correlation normalization before applying detailed balance or fluctuation–dissipation.
32 min - 07
Nuclear magnetic resonance and spin relaxation
Separate a static shift from frequency-filtered fluctuations and state the conditions behind simple relaxation formulas.
32 min - 08
Muon spin rotation and local magnetic fields
Infer a local field from precession while separating static distributions, dynamics, background, and stopping fractions.
32 min - 09
Heat capacity and thermal transport diagnostics
Distinguish thermodynamic state counting from heat-current transport and test the assumptions behind low-temperature fits.
32 min - 10
Cross-probe consistency and material sample quality
Compare forward responses and shared uncertainties before assigning a unique microscopic state.
