On multipoint correlation functions in the Sinh-Gordon 1+1 dimensional quantum field theory [PDF]
This work provides a closed, explicit and rigorous expression for the appropriately truncated $k$-point function of the integrable 1+1 dimensional Sinh-Gordon quantum field theory. The results are obtained within the bootstrap program setting.

Quantum-critical properties of the long-range transverse-field Ising model from quantum Monte Carlo simulations [PDF]
Physical review B, 2021 The quantum-critical properties of the transverse-field Ising model with algebraically decaying interactions are investigated by means of stochastic series expansion quantum Monte Carlo, on both the one-dimensional linear chain and the two-dimensional ...

NON RELATIVISTIC QUANTUM FIELD THEORY: DYNAMICS AND IRREVERSIBILITY
Anales (Asociación Física Argentina), 2022 We study aspects of quantum field theory at finite density using techniques and concepts from quantum information theory. We focus on massive Dirac fermions with chemical potential in 1+1 space-time dimensions.

String Theory Explanation of Large-Scale Anisotropy and Anomalous Alignment [PDF]
Reports in Advances of Physical Sciences, 2018 The discovery of anomalies in the cosmic microwave background (CMB) indicates large-scale anisotropies, non-Gaussian distributions, and anomalous alignments of the quadrupole and octupole modes of the anisotropy with each other and with both the ecliptic

Equilibrium States in Thermal Field Theory and in Algebraic Quantum Field Theory [PDF]
Annales de l'Institute Henri Poincare. Physique theorique, 2019 We compare the construction of equilibrium states at finite temperature for self-interacting massive scalar quantum field theories on Minkowski spacetime proposed by Fredenhagen and Lindner (Commun Math Phys 332:895, 2014) with results obtained in ...

Non-Archimedean Statistical Field Theory [PDF]
, 2020 We construct in a rigorous mathematical way interacting quantum field theories on a p-adic spacetime. The main result is the construction of a measure on a function space which allows a rigorous definition of the partition function.

Exchange-correlation orbital functionals in current-density functional theory: Application to a quantum dot in magnetic fields [PDF]
Physical Review B, 2008 The description of interacting many-electron systems in external magnetic fields is considered in the framework of the optimized effective potential method extended to current-spin-density functional theory. As a case study, a two-dimensional quantum dot in external magnetic fields is investigated.

Unfolded dynamics approach and quantum field theory
Journal of High Energy Physics, 2023 We study quantization of a self-interacting scalar field within the unfolded dynamics approach. To this end we find and analyze a classical unfolded system describing 4d off-shell scalar field with a general self-interaction potential.
