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…
Cheshire Cat resurgence, Self-resurgence and Quasi-Exact Solvable Systems
Can Kozçaz, Tin Sulejmanpasic, Yuya Tanizaki +1
We explore a one parameter -deformation of the quantum-mechanical Sine-Gordon and Double-Well potentials which we call the Double Sine-Gordon (DSG) and the Tilted Double Well (T…
Global symmetries, volume independence and continuity
Tin Sulejmanpasic
We discuss quantum field theories with global and symmetries for which the temporal direction is compactified on a circle of size with periodicity of fields up t…
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…
Confinement in the bulk, deconfinement on the wall: infrared equivalence between compactified QCD and quantum magnets
Tin Sulejmanpasic, Hui Shao, Anders W. Sandvik +1
In a spontaneously dimerized quantum antiferromagnet, spin-1/2 excitations (spinons) are confined in pairs by strings akin to those confining quarks in non-abelian gauge theories.…
