Harnessing finite-size effects to gauge aging in the Ising model
Dustin Warkotsch, Malte Henkel, Wolfhard Janke
The authors analyze the relaxation of the two‑dimensional Ising model by examining the two‑time autocorrelator and exploiting finite‑size effects to obtain precise estimates of the…
Exact solution of the Glauber-Ising model on the finite-length semi-open chain
Malte Henkel
The exact time-space correlation function of the Glauber-Ising model, quenched to temperature and on a semi-open lattice of finite size , is obtained. This also allow…
Fractal and Spectral Dimensions as Determinants of Thermal Ablation Outcomes in Cancer Tissues
Mario Olmo-Fajardo, Alexander López, Malte Henkel +1
Clinical thermal ablation outcomes display significant variability that classical bio-heat models cannot fully explain. One reason may lie in the fractal architecture of biological…
Schrödinger-invariance in phase-ordering kinetics
Stoimen Stoimenov, Malte Henkel
The generic shape of the single-time and two-time correlators in non-equilibrium phase-ordering kinetics with is obtained from the co-variance of the four-point response fu…
Schrödinger-invariance in non-equilibrium critical dynamics
Malte Henkel, Stoimen Stoimenov
The scaling functions of single-time and two-time correlators in systems undergoing non-equilibrium critical dynamics with dynamical exponent are predicted from a new time-…
Limitations of the Markovian approximation in the harmonic oscillator
Michele Coppola, Zoubair Daouma, Malte Henkel
The quantum fluctuation-dissipation theorem is a central ingredient in the construction of quantum dynamics of Brownian motion which necessarily is non-Markovian. Yet, often Markov…
