Real-time spin systems from lattice field theory
We construct a lattice field theory method for computing the real-time dynamics of spin systems in a thermal bath. This is done by building on...

Conformal Field Theory from Lattice Fermions
We provide a rigorous lattice approximation of conformal field theories given in terms of lattice fermions in 1+1-dimensions, focussing on free...

Discrete Field Theory: Symmetries and Conservation Laws
We present a general algorithm constructing a discretization of a classical field theory from a Lagrangian. We prove a new discrete Noether theorem...

Conformal Field Theory at the Lattice Level: Discrete Complex Analysis and Virasoro Structure
Critical statistical mechanics and Conformal Field Theory (CFT) are conjecturally connected since the seminal work of Beliavin et al. (Nucl Phys B...

Perfect discretizations as a gateway to one-loop partition functions for 4D gravity
Lattice actions and amplitudes that perfectly mirror continuum physics are known as perfect discretizations. Such perfect discretizations naturally...

Self-dual U(1) lattice field theory with a θ-term
We study U(1) gauge theories with a modified Villain action. Such theories can naturally be coupled to electric and magnetic matter, and display...

Slit-Strip Ising Boundary Conformal Field Theory 1: Discrete and Continuous Function Spaces
This is the first in a series of articles about recovering the full algebraic structure of a boundary conformal field theory (CFT) from the scaling...

On the continuum limit of the entanglement Hamiltonian of a sphere for the free massless scalar field
We study the continuum limit of the entanglement Hamiltonian of a sphere for the massless scalar field in its ground state by employing the lattice...

The chiral separation effect from lattice QCD at the physical point
In this paper we study the Chiral Separation Effect by means of first-principles lattice QCD simulations. For the first time in the literature, we...

Lattice studies of supersymmetric gauge theories
Supersymmetry plays prominent roles in the study of quantum field theory and in many proposals for potential new physics beyond the standard model....

Conserved energy–momentum tensor for real-time lattice simulations
We derive an expression for the energy–momentum tensor in the discrete lattice formulation of pure glue QCD. The resulting expression satisfies the...

Essentials of Lattice Gauge Theories (LGT)
This chapter gives an introduction to Lattice Gauge Theories (LGT). After an introduction into the history of the subject beginning with Wegner’s...

Fractional Hall conductivity and spin-c structure in solvable lattice Hamiltonians
The Kapustin-Fidkowski no-go theorem forbids U(1) symmetric topological orders with non-trivial Hall conductivity in (2+1)d from admitting commuting...

Injecting the UV into the bootstrap: Ising Field Theory
We merge together recent developments in the S-matrix bootstrap program to develop a dual setup in 2 space-time dimensions incorporating scattering...

The chiral condensate of Nf = 2 + 1 QCD from the spectrum of the staggered Dirac operator
We compute the chiral condensate of 2 + 1 QCD from the mode number of the staggered Dirac operator, performing controlled extrapolations to both the...

Hadronic vacuum polarization in the muon g − 2: the short-distance contribution from lattice QCD
We present results for the short-distance window observable of the hadronic vacuum polarization contribution to the muon g – 2, computed via the...

Petz recovery from subsystems in conformal field theory
We probe the multipartite entanglement structure of the vacuum state of a CFT in 1+1 dimensions, using recovery operations that attempt to...

Monte Carlo Evaluation of the Continuum Limit of the Two-Point Function of the Euclidean Free Real Scalar Field Subject to Affine Quantization
We study canonical and affine versions of the quantized covariant Euclidean free real scalar field-theory on four dimensional lattices through the...

Steady electric currents in magnetized QCD and their use for the equation of state
In this paper we study the emergence of steady electric currents in QCD as a response to a non-uniform magnetic background using lattice simulations...

Lattice fermions as spectral graphs
We study lattice fermions from the viewpoint of spectral graph theory (SGT). We find that a fermion defined on a certain lattice is identified as a...
