Stochastic inflation from quantum field theory and the parametric dependence of the effective noise amplitude
Jens O. Andersen, Magdalena Eriksson, Anders Tranberg
The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but stochastic evolution equation. The stochastic noise repr…
supersymmetric Yang-Mills thermodynamics from effective field theory
Jens O. Andersen, Qianqian Du, Michael Strickland +1
The free energy density of supersymmetric Yang-Mills theory in four space-time dimensions is derived through second order in the 't Hooft coupling at finite temper…
QCD phase diagram in a constant magnetic background. Inverse magnetic catalysis: where models meet the lattice
Jens O. Andersen
Magnetic catalysis is the enhancement of a condensate due to the presence of an external magnetic field. Magnetic catalysis at is a robust phenomenon in low-energy theories a…
Quark condensates and magnetization in chiral perturbation theory in a uniform magnetic field
Prabal Adhikari, Jens O. Andersen
We reconsider the problem of calculating the vacuum free energy (density) of QCD and the shift of the quark condensates in the presence of a uniform background magnetic field using…
