Derivation of field theory for the classical dimer model using bosonization
, 2023 We derive a field theory for the two-dimensional classical dimer model by applying bosonization to Lieb's (fermionic) transfer-matrix solution. Our constructive approach gives results that are consistent with the well-known height theory, previously ...

Overlaps after quantum quenches in the sine-Gordon model
Physics Letters B, 2017 We present a numerical computation of overlaps in mass quenches in sine-Gordon quantum field theory using truncated conformal space approach (TCSA). To improve the cut-off dependence of the method, we use a novel running coupling definition which has a ...

Inverse Renormalization Group in Quantum Field Theory [PDF]
Physical Review Letters, 2022 We propose inverse renormalization group transformations within the context of quantum field theory that produce the appropriate critical fixed point structure, give rise to inverse flows in parameter space, and evade the critical slowing down effect in calculations pertinent to criticality.

Nuclear Physics B, 2015 We study the SU(2)k Wess–Zumino–Novikov–Witten (WZNW) theory perturbed by the trace of the primary field in the adjoint representation, a theory governing the low-energy behavior of a class of strongly correlated electronic systems.

Taking Particle Physics Seriously: a Critique of the Algebraic Approach to Quantum Field Theory [PDF]
, 2011 I argue against the currently-prevalent view in philosophy of physics that algebraic quantum field theory (AQFT) is the correct framework for philosophy of quantum field theory and that "conventional" quantum field theory (CQFT), of the sort used in ...

LeClair-Mussardo series for two-point functions in Integrable QFT
Journal of High Energy Physics, 2018 We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations.

QUANTUM GROUP SCHRÖDINGER FIELD THEORY [PDF]
Modern Physics Letters A, 1993 We show that a quantum deformation of quantum mechanics given in a previous work is equivalent to quantum mechanics on a nonlinear lattice with step size ∆x=(1−q)x. Then, based on this, we develop the basic formalism of quantum group Schrödinger field theory in one spatial quantum dimension, and explicitly exhibit the SU q(2) covariant algebras ...

Cosmological implications of the hydrodynamical phase of group field theory [PDF]
, 2021 In this review we focus on the main cosmological implications of the Group Field Theory approach, according to which an effective continuum macroscopic dynamics can be extracted from the underlying formalism for quantum gravity.

Composite operators near the boundary
Journal of High Energy Physics, 2020 We use renormalization group methods to study composite operators existing at a boundary of an interacting conformal field theory. In particular we relate the data on boundary operators to short-distance (near-boundary) divergences of bulk two-point ...

Statistical predictions from anarchic field theory landscapes [PDF]
, 2010 Consistent coupling of effective field theories with a quantum theory of gravity appears to require bounds on the rank of the gauge group and the amount of matter. We consider landscapes of field theories subject to such to boundedness constraints.
