Phase diagram of the two-dimensional O(3) model from dual lattice simulations
Falk Bruckmann, Christof Gattringer, Thomas Kloiber +1
We have simulated the asymptotically free two-dimensional O(3) model at nonzero chemical potential using the model's dual representation. We first demonstrate how the latter solves…
Aspects of Perturbation theory in Quantum Mechanics: The BenderWu Mathematica package
Tin Sulejmanpasic, Mithat Ünsal
We discuss a general setup which allows the study of the perturbation theory of an arbitrary, locally harmonic 1D quantum mechanical potential as well as its multi-variable (many-b…
The two-dimensional O(3) model at nonzero density: from dual lattice simulations to repulsive bosons
Falk Bruckmann, Christof Gattringer, Thomas Kloiber +1
We discuss the thermodynamics of the O(3) nonlinear sigma model in 1+1 dimensions at nonzero chemical potential (equivalent to a magnetic field). In its conventional field theory r…
