We propose to downgrade the full space-time metric of general relativity to a relativistic anisotropy of the mass tensor characterizing the velocity-momentum relation. The “square root” of the metric or mass tensor is used to construct a composite Yang-Mills theory, thus building an elegant bridge to the present theories of electroweak and strong interactions. The proposed alternative theory of gravity reproduces the famous high-precision predictions of Einstein’s general relativity, but makes black holes less singular. more

"ALL men by nature desire to know,'' states Aristotle in the famous first sentence of his Metaphysics. Knowledge about fundamental particles and interactions, that is, knowledge about the deepest aspects of matter, is certainly high if not top on the priority list, not only for physicists and philosophers. The goal of our work is to contribute to this knowledge by going beyond the usual presentations of quantum field theory in physics textbooks, both in mathematical approach and by critical reflections inspired by epistemology, that is, by the branch of philosophy also referred to as the theory of knowledge. more

In the context of solid state-​based quantum information processing, external control in quantum optics, quantum transport through meso-​ and nanoscale structures, quantum tunneling in macroscopic systems, quantum Brownian motors, and biological reactions, for example, quantum dissipation is an important subject. We have proposed a general thermodynamic framework for dissipative quantum systems in weak contact with classical equilibrium and nonequilibrium environments. more
