From freely falling frames to the Lorentz gauge-symmetry group and a Hamiltonian composite theory of gravitation
Hans Christian Öttinger
The concept of freely falling frames suggests that gravity exhibits a local Lorentz gauge symmetry and requires a background Minkowski reference frame. The gauge vector fields of a…
Elementary particles with nonzero spin must be massless
Hans Christian Öttinger
We present an ontological argument why elementary particles with nonzero spin must be massless. This argument implies that, from an ontological perspective, the massive quarks and…
Quantum entanglement without superposition
Hans Christian Öttinger
Superposition states are at the origin of many paradoxes in quantum mechanics. By unraveling the von Neumann equation for density matrices, we develop a superposition-free formulat…
Fixed Point Quantum Monte Carlo
Romain Chessex, Massimo Borrelli, Hans Christian Öttinger
We present a new approach to the study of equilibrium properties in many-body quantum physics. Our method takes inspiration from Density Matrix Quantum Monte Carlo and incorporates…
A dynamically constrained Yang-Mills theory with Lorentz symmetry group as an alternative theory of gravity
Hans Christian Öttinger
We develop the complete composite theory of gravity, in which the gauge vector fields of the Yang-Mills theory with Lorentz symmetry group are expressed in terms of the tetrad vari…
Coordinate conditions and field equations for pure composite gravity
Hans Christian Öttinger
Whenever an alternative theory of gravity is formulated in a background Minkowski space, the conditions characterizing admissible coordinate systems, in which the alternative theor…
