Modeling a particle detector in field theory
New Journal of Physics, 2009 Particle detector models allow to give an operational definition to the particle content of a given quantum state of a field theory. The commonly adopted Unruh-DeWitt type of detector is known to undergo temporary transitions to excited states even when at rest and in the Minkowski vacuum.

A new matrix model for noncommutative field theory [PDF]
Physics Letters B, 2004 We describe a new regularization of quantum field theory on the noncommutative torus by means of one-dimensional matrix models. The construction is based on the Elliott-Evans inductive limit decomposition of the noncommutative torus algebra. The matrix trajectories are obtained via the expansion of fields in a basis of new noncommutative solitons ...

The Snyder Model and Quantum Field Theory
Ukrainian Journal of Physics, 2019 We review the main features of the relativistic Snyder model and its generalizations. We discuss the quantum field theory on this background using the standard formalism of noncommutative QFT and discuss the possibility of obtaining a finite theory.

THE MARINARI-PARISI MODEL AND COLLECTIVE FIELD THEORY [PDF]
Modern Physics Letters A, 1992 We derive the supersymmetric collective field theory for the Marinari-Parisi model. For a specific choice of the superpotential, to leading order we find a one-parameter family of ground states which can be connected via instantons. At this level of analysis the instanton size implied by the underlying matrix model does not appear.

THEORY OF THE RANDOM FIELD ISING MODEL [PDF]
, 1997 A review is given on some recent developments in the theory of the Ising model in a random field. This model is a good representation of a large number of impure materials. After a short repetition of earlier arguments, which prove the absence of ferromagnetic order in $d\le 2$ space dimensions for uncorrelated random fields, we consider different ...

SUPERCONFORMAL FIELD THEORY WITH BOUNDARY: SPIN MODEL [PDF]
Modern Physics Letters A, 1999 The GSO projected superconformal field theory (spin model) with boundary is studied. Boundary states, one-point structure constants, and "bootstrap" equations for the boundary–bulk structure constants are derived.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number
