Canonical quantization of lattice Chern-Simons theory
Theodore Jacobson, Tin Sulejmanpasic
We discuss the canonical quantization of Chern-Simons theory on a spatial lattice. In addition to the usual local Gauss law constraints, the physical Hilbert space is defi…
Phases of theories with 1-form symmetry and the roles of center vortices and magnetic monopoles
Mendel Nguyen, Tin Sulejmanpasic, Mithat Ünsal
We analyze the phases of theories which only have a microscopic 1-form symmetry, starting with a topological BF theory and deforming it in accordance with microscopi…
Remarks on QCD with fundamental and adjoint matter
Mohamed M. Anber, Nakarin Lohitsiri, Tin Sulejmanpasic
We study 4-dimensional SU(N) gauge theory with one adjoint Weyl fermion and fundamental matter - either bosonic or fermionic. Symmetries, their 't Hooft anomalies, and the Vafa-Wit…
Modified Villain formulation of abelian Chern-Simons theory
Theodore Jacobson, Tin Sulejmanpasic
We formulate Chern-Simons theory on a Euclidean spacetime lattice using the modified Villain approach. Various familiar aspects of continuum Chern-Simons theory such as le…
Lattice Quantum Villain Hamiltonians: Compact scalars, gauge theories, fracton models and Quantum Ising model dualities
Lucca Fazza, Tin Sulejmanpasic
We construct Villain Hamiltonians for compact scalars and abelian gauge theories. The Villain integers are promoted to integral spectrum operators, whose canonical conjugates are n…
Comments on QCD and anomalies with fundamental and adjoint matter
Nakarin Lohitsiri, Tin Sulejmanpasic
't Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a -symmetric theory where one c…
Phase structure of self-dual lattice gauge theories in 4d
Mariia Anosova, Christof Gattringer, Nabil Iqbal +1
We discuss U(1) lattice gauge theory models based on a modified Villain formulation of the gauge action, which allows coupling to bosonic electric and magnetic matter. The formulat…
Universality between vector-like and chiral quiver gauge theories: Anomalies and domain walls
Tin Sulejmanpasic, Yuya Tanizaki, Mithat Ünsal
We study low-energy dynamics of chiral quiver gauge theories in connection with super Yang-Mills (SYM) theory, and quantum chromodynamics with bi-fundam…
Bions and Instantons in Triple-well and Multi-well Potentials
Gerald V. Dunne, Tin Sulejmanpasic, Mithat Unsal
Quantum systems with multiple degenerate classical harmonic minima exhibit new non-perturbative phenomena which are not present for the double-well and periodic potentials. The sim…
Instantons in the Hofstadter butterfly: difference equation, resurgence and quantum mirror curves
Zhihao Duan, Jie Gu, Yasuyuki Hatsuda +1
We study the Harper-Hofstadter Hamiltonian and its corresponding non-perturbative butterfly spectrum. The problem is algebraically solvable whenever the magnetic flux is a rational…
Critical Points at Infinity, Non-Gaussian Saddles, and Bions
Alireza Behtash, Gerald V. Dunne, Thomas Schaefer +2
It has been argued that many non-perturbative phenomena in quantum mechanics (QM) and quantum field theory (QFT) are determined by complex field configurations, and that these cont…
C-P-T anomaly matching in bosonic quantum field theory and spin chains
Tin Sulejmanpasic, Yuya Tanizaki
We consider the nonlinear sigma model with the -term and its linear counterpart in 1+1D. The model has discrete time-reflection and space-reflection symmetries at any …
High order perturbation theory for difference equations and Borel summability of quantum mirror curves
Jie Gu, Tin Sulejmanpasic
We adapt the Bender-Wu algorithm to solve perturbatively but very efficiently the eigenvalue problem of "relativistic" quantum mechanical problems whose Hamiltonians are difference…
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…
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.…
Toward Picard-Lefschetz Theory of Path Integrals, Complex Saddles and Resurgence
Alireza Behtash, Gerald V. Dunne, Thomas Schaefer +2
We show that the semi-classical analysis of generic Euclidean path integrals necessarily requires complexification of the action and measure, and consideration of complex saddle so…
Complexified path integrals, exact saddles and supersymmetry
Alireza Behtash, Gerald V. Dunne, Thomas Schaefer +2
In the context of two illustrative examples from supersymmetric quantum mechanics we show that the semi-classical analysis of the path integral requires complexification of the con…
The curious incident of multi-instantons and the necessity of Lefschetz thimbles
Alireza Behtash, Erich Poppitz, Tin Sulejmanpasic +1
We show that compatibility of supersymmetry with exact semi-classics demands that in calculating multi-instanton amplitudes, the "separation" quasi-zeromode must be complexified an…
Hidden topological angles and Lefschetz thimbles
Alireza Behtash, Tin Sulejmanpasic, Thomas Schaefer +1
We demonstrate the existence of hidden topological angles (HTAs) in a large class of quantum field theories and quantum mechanical systems. HTAs are distinct from theta-parameters…

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…
