    Beyond the Boltzmann factor for corrections to scaling in ferromagnetic materials and critical fluids

    The Boltzmann factor comes from the linear change in entropy of an infinite heat bath during a local fluctuation; small systems have significant nonlinear terms. We present theoretical arguments, experimenta...

    Fluctuation-theory constraint for extensive entropy in Monte-Carlo simulations

    The entropy per particle in most Monte-Carlo simulations is size dependent due to correlated energy fluctuations. Guided by nanothermodynamics, we find a constraint for the Ising model that enhances the fluctu...

    Slow Dielectric Relaxation of Supercooled Liqutos Investigated by Nonresonant Spectral Hole Burning

    When supercooled propylene carbonate and glycerol are subjected to a large-amplitude, low-frequency electric field, a spectral hole develops in their dielectric relaxation that is significantly narrower than t...

    Pulsed dielectric spectroscopy of supercooled liquids

    Pulsed dielectric spectroscopy is introduced as a technique for selectively emphasizing specific components of the non-exponential dielectric response of matter. Samples studied include supercooled liquid prop...

    Magnetic Evidence for Reentrant Field-Induced Spin Density Waves

    High magnetic field (to 31T) d.c. magnetization measurements on the quasi-one dimensional organic conductor (TMTSF) 2ClO4 yield thermodynamic evidence for the reentrance of a metallic phase from the magnetic fiel...

    Magnetic Field Induced Transitions in Organic Conductors: Experiments

    The Bechgaard salts, (TMTSF)2x (where X is ClO4, PF6, ReO4 etc.), are best known for being the first organic superconductors, and exhibiting a rich phase diagram with spin density wave (SDW) and charge density wa...

    High-sensitivity magnetic resonance by SQUID detection

    A SQUID magnetometer has been used to detect electron paramagnetic resonance of the Ce%3 ion in dilute CMN (1 %) at low temperatures down to 10 mK. This method of detecting magnetic resonance allows a greater sig...
