Emergence of Spin Order in Two-Dimensional Quantum Heisenberg Antiferromagnets
Christoph P. Hofmann
Counterintuitive order-disorder phenomena emerging in antiferromagnetically coupled spin systems have been reported in various studies. Here we perform a systematic effective field…
Diamagnetic and Paramagnetic Phases in Low-Energy Quantum Chromodynamics
Christoph P. Hofmann
While it is known that the QCD vacuum in a magnetic background exhibits both diamagnetic and paramagnetic characteristics in the low-energy domain, a systematic investigation of th…
Thermomagnetic Properties of QCD
Christoph P. Hofmann
We explore the low-energy regime of quantum chromodynamics subjected to an external magnetic field by deriving the two-loop representations for the entropy density and the magnetiz…
Antiferromagnetic Dispersion Relations and Nature of Magnon Pressure
Christoph P. Hofmann
We derive higher-order corrections in the magnon dispersion relations for two- and three-dimensional antiferromagnets exposed to magnetic and staggered fields that are mutually ali…
Spin Order and Entropy in Antiferromagnetic Films Subjected to Magnetic Fields
Christoph P. Hofmann
Using systematic effective field theory, we explore the properties of antiferromagnetic films subjected to magnetic and staggered fields that are either mutually aligned or mutuall…
Chiral Perturbation Theory Analysis of the Quark Condensate in a Magnetic Field
Christoph P. Hofmann
We present two-loop results for the quark condensate in an external magnetic field within chiral perturbation theory using coordinate space techniques. At finite temperature, we ex…
