Quantum scars in quantum field theory
Physical Review D, 2023 We develop the theory of quantum scars for quantum fields. By generalizing the formalisms of Heller and Bogomolny from few-body quantum mechanics to quantum fields, we find that unstable periodic classical solutions of the field equations imprint themselves in a precise manner on bands of energy eigenfunctions.

Computation, 2016 An extremely interesting problem in aero-hydrodynamics is the sound radiation of a single vortical structure. Currently, this type of problem is mainly considered for an incompressible medium. In this paper a method was developed to take into account the

Coulomb Problem for Classical Spinning Particles
Universe, 2023 We consider the motion of a weakly relativistic charged particle with an arbitrary spin in central potential e/r in terms of classical mechanics. We show that the spin–orbital interaction causes the precession of the plane of orbit around the vector of ...

Quaternionic Quantum Field Theory [PDF]
Physical Review Letters, 1985 Abstract Up to this point our discussion of relativistic quaternionic wave equations has dealt with the first quantized case, in which the wave fields are quaternions in the right-acting algebra spanned by 1, i,j,k, with c-number-valued real components.

Quantum Algorithms for Quantum Field Theories [PDF]
Science, 2012 Quantum Leap? Quantum computers are expected to be able to solve some of the most difficult problems in mathematics and physics. It is not known, however, whether quantum field theories (QFTs) can be simulated efficiently with a quantum computer.

BQP-completeness of scattering in scalar quantum field theory [PDF]
Quantum, 2017 Recent work has shown that quantum computers can compute scattering probabilities in massive quantum field theories, with a run time that is polynomial in the number of particles, their energy, and the desired precision.

Toward a Definition of Complexity for Quantum Field Theory States. [PDF]
Physical Review Letters, 2017 We investigate notions of complexity of states in continuous many-body quantum systems. We focus on Gaussian states which include ground states of free quantum field theories and their approximations encountered in the context of the continuous version ...

PERTURBATIVE QUANTUM FIELD THEORY [PDF]
Challenges for the 21st Century, 2001 This talk introduces perturbative quantum field on a heuristic level. It is directed at an audience familiar with elements of quantum mechanics, but not necessarily with high energy physics. It includes a discussion of the strategies behind experimental tests of fundamental theories, and of the field theory interpretations of these tests.

Quantum Gravity as Topological Quantum Field Theory [PDF]
, 1995 The physics of quantum gravity is discussed within the framework of topological quantum field theory. Some of the principles are illustrated with examples taken from theories in which space-time is three dimensional.Comment: 23 pages, amstex, JMP special
