Local subtractions and renormalization-group monotonicity: exact defect and sphere flows
Francesco Scardino
We ask when the sphere free energy of a quantum field theory, after subtraction of its local counterterms in a fixed renormalization prescription, decreases monotonically along the…
Nonadditivity in Quantum Field Theory: Replica Energies, Scaling Filters, and the Renormalization Group
Giacomo Santoni, Francesco Scardino
Extensive systems have a simple thermodynamic signature: the dimensionless canonical free energy scales homogeneously with the size of the system. We show that the failure of this…
Constrained Symplectic Quantization: Disclosing the Deterministic Framework Behind Quantum Field Theory
Francesco Scardino, Martina Giachello, Giacomo Gradenigo
Symplectic quantization is a functional approach to quantum field theory that allows sampling of quantum fluctuations directly in Minkowski space time by means of a Hamiltonian dyn…
Constrained Symplectic Quantization II: The Free Scalar Field
Francesco Scardino, Martina Giachello, Giacomo Gradenigo
Constrained symplectic quantization is a functional formulation of quantum field theory in which quantum fluctuations are sampled through a deterministic Hamiltonian flow in an aux…
Update on the computation of the quenched Yang-Mills lattice spectrum
Andrea Falzetti, Matteo Lombardi, Mauro Lucio Papinutto +1
We report on our continued efforts to measure the glueball and meson spectra in SU() Yang-Mills theory and QCD with the aim of extrapolating to the large- limit. In particula…
Constrained Symplectic Quantization: Disclosing the Deterministic Framework Behind Quantum Mechanics
Martina Giachello, Francesco Scardino, Giacomo Gradenigo
Symplectic quantization is a functional approach to quantum field theory that allows sampling of quantum fluctuations directly in Minkowski space time by means of a generalized Ham…
The scheme independent 3-sphere free energy is not a monotone F-function
Giacomo Santoni, Francesco Scardino
We study the natural scheme-independent quantity obtained from the three-sphere partition function of a -dimensional quantum field theory by removing all local counterterm a…
Constrained Symplectic Quantization I: the Quantum Harmonic Oscillator
Martina Giachello, Francesco Scardino, Giacomo Gradenigo
Symplectic quantization is a functional approach to quantum field theory that allows sampling of quantum fluctuations directly in Minkowski space-time by means of a generalized mic…
Symplectic Quantization and Minkowskian Statistical Mechanics: simulations on a 1+1 lattice
Martina Giachello, Giacomo Gradenigo, Francesco Scardino
We introduce symplectic quantization, a novel functional approach to quantum field theory which allows to sample quantum fields fluctuations directly in Minkowski space-time, at va…
Symplectic Quantization: numerical results for the Feynman propagator on a 1+1 lattice and the theoretical relation with Quantum Field Theory
Martina Giachello, Francesco Scardino, Giacomo Gradenigo
We present here the first lattice simulation of symplectic quantization, a new functional approach to quantum field theory which allows to define an algorithm to numerically sample…
