Numerical approach to the modular operator for fermionic systems
Henning Bostelmann, Daniela Cadamuro, Christoph Minz
We numerically approximate the Tomita-Takesaki modular operator for local subalgebras of the 1+1-dimensional massive Majorana field. Our method works at the one-particle level with…

Local symmetries in partially ordered sets
Christoph Minz
Partially ordered sets (posets) play a universal role as an abstract structure in many areas of mathematics. For finite posets, an explicit enumeration of distinct partial orders o…

Do causal sets have symmetries?
Christoph Minz
Causal sets are locally finite, partially ordered sets (posets), which are considered as discrete models of spacetimes. On the one hand, causal sets corresponding to a spacetime ma…
