Roundtable: What can we learn about confinement and anomalous effects in QCD using analog systems?
M. Cristina Diamantini, Dmitri E. Kharzeev, Alexander Molochkov +2
We discuss a number of examples for recent connections between emergent phenomena in many-body systems in atomic and condensed matter physics, and confinement and other non-perturb…
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…
The absence of IR renormalons in gauge theories on and what it means for resurgence
Mohamed M. Anber, Tin Sulejmanpasic
We analyze the renormalon diagram of gauge theories on . In particular, we perform exact one loop calculations for the vacuum polarization in QCD wit…
Nonlinear sigma models at nonzero chemical potential: breaking up instantons and the phase diagram
Falk. Bruckmann, Tin Sulejmanpasic
We consider asymptotically free nonlinear sigma models in two dimensions which, due to their internal symmetries, allow for a conserved charge. Introducing nonzero chemical potenti…
