Quantum Fields on Noncommutative Spacetimes: Theory and Phenomenology
Symmetry, Integrability and Geometry: Methods and Applications, 2010 In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance.

Critical Notice: "The Conceptual Development of 20th Century Field Theories", by Tian Yu Cao [PDF]
, 2001 Cao makes two claims of particular philosophical interest, in his book "The Conceptual Development of 20th Century Field Theories". (i) The history of these developments refutes Kuhn's relativistic epistemology, and (tacitly) (2) the question of realism ...

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5
Advanced Functional Materials, EarlyView.We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

On the representation of minimal form factors in integrable quantum field theory
Nuclear Physics BIn this paper, we propose a new representation of the minimal form factors in integrable quantum field theories. These are solutions of the two-particle form factor equations, which have no poles on the physical sheet.

Lefschetz thimbles and quantum phases in zero-dimensional bosonic models
European Physical Journal C: Particles and Fields, 2020 In this paper, by analyzing the underlyingLefschetz-thimble structure, we investigate quantum phases (or quantum critical points) in zero-dimensional scalar field theories with complex actions.

Against Field Interpretations of Quantum Field Theory [PDF]
, 2008 I examine some problems standing in the way of a successful ``field interpretation'' of quantum field theory. The most popular extant proposal depends on the Hilbert space of ``wavefunctionals.'' But since wavefunctional space is unitarily equivalent to ...

Advanced Functional Materials, EarlyView.A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Aspects of supersymmetric field theories in four and six dimensions [PDF]
, 2011 PhDSupersymmetry is an important concept in modern high energy physics. It has found many applications in theoretical considerations of supersymmetric gauge theories as well as in phenomenological approaches to physics beyond the Standard Model.

A one-loop test of the near-AdS2/near-CFT1 correspondence
Journal of High Energy Physics, 2020 We analyze quantum fluctuations around black hole solutions to the Jackiw-Teitelboim model. We use harmonic analysis on Euclidean AdS2 to show that the logarithmic corrections to the partition function are determined entirely by quadratic holomorphic ...

A Dynamical Mapping Method in Nonrelativistic Models of Quantum Field Theory [PDF]
Journal of Nonlinear Mathematical Physics, 1997 The solutions of Heisenberg equations and two-particles eigenvalue problems for nonrelativistic models of current-current fermion interaction and $N, Θ$ model are obtained in the frameworks of dynamical mapping method. The equivalence of different types of dynamical mapping is shown.
