Casimir–Polder Force on Atoms or Nanoparticles from Gapped and Doped Graphene: Asymptotic Behavior at Large Separations by Galina L. Klimchitskaya, Vladimir M. Mostepanenko

“…The reflection coefficients expressed via the polarization tensor of graphene, found based on the first principles of thermal quantum field theory, are used. It is shown that for graphene the separation distances, starting from which the zero-frequency term of the Lifshitz formula contributes more than 99% of the total Casimir–Polder force, are less than the standard thermal length. …”

Are Virtual Particles Less Real? by Gregg Jaeger

“…The question of whether virtual quantum particles exist is considered here in light of previous critical analysis and under the assumption that there are particles in the world as described by quantum field theory. The relationship of the classification of particles to quantum-field-theoretic calculations and the diagrammatic aids that are often used in them is clarified. …”

Decoherence effects on lepton number violation from heavy neutrino-antineutrino oscillations by Stefan Antusch, Jan Hajer, Johannes Rosskopp

“…Abstract We study decoherence effects and phase corrections in heavy neutrino-antineutrino oscillation ( N N ¯ O $$ N\overline{N}O $$ s), based on quantum field theory with external wave packets. Decoherence damps the oscillation pattern, making it harder to resolve experimentally. …”

Exact large-scale correlations in integrable systems out of equilibrium by Benjamin Doyon

“…In particular, we find Leclair-Mussardo-type infinite form-factor series in integrable quantum field theory, and exact Euler-scale two-point functions of exponential fields in the sinh-Gordon model and of powers of the density field in the Lieb-Liniger model. …”

QFT without infinities and hierarchy problem by Sander Mooij, Mikhail Shaposhnikov

“…The standard way to do computations in Quantum Field Theory (QFT) often results in the requirement of dramatic cancellations between contributions induced by a “heavy” sector into the physical observables of the “light” (or low energy) sector – the phenomenon known as “technical hierarchy problem”. …”

Symmetry resolution of the computable cross-norm negativity of two disjoint intervals in the massless Dirac field theory by Andrea Bruno, Filiberto Ares, Sara Murciano, Pasquale Calabrese

“…Abstract We investigate how entanglement in the mixed state of a quantum field theory can be described using the cross-computable norm or realignment (CCNR) criterion, employing a recently introduced negativity. …”

Statistics of the Bifurcation in Quantum Measurement by Karl-Erik Eriksson, Kristian Lindgren

“…Previous obstacles for understanding the measurement process are removed by basing the analysis of the interaction between <inline-formula> <math display="inline"> <semantics> <mi>&#956;</mi> </semantics> </math> </inline-formula> and the measurement device on quantum field theory. This formulation shows how inverse processes take part in the interaction and introduce a non-linearity, necessary for the bifurcation of quantum measurement. …”

Comments on the cosmological constant in generalized uncertainty models by Michael Bishop, Joey Contreras, Peter Martin, Douglas Singleton

“…The existence of a small, non-zero cosmological constant is one of the major puzzles in fundamental physics. Naively, quantum field theory arguments would imply a cosmological constant which is up to 10,120 times larger than the observed one. …”

Computational method for determining the bound state oscillator frequency by A Jahanshir, A Tarasenka

“…Creation and annihilation operator’s method that is associated with the system was proposed to determine the oscillator frequency of the bound system which consists of two or more particles, as a function of the orbital quantum number, which is the main parameter to describe the interaction between particles that create new bounding systems like charmonium, hyperatoms, pentaquark, etc. Using quantum field theory and quantum electrodynamics methods, we are found that the creation of a bound state occurs if the coupling constant be small, and masses of gauge bosons also be very small in comparison with masses of constituent particles. …”

The effect of anisotropic field on magnon dispersion of antiferromagnetic metal fluoride materials by Desalegn Tefera Yimer, Pooran Singh, Chernet Amente Geffe

“…The analysis is done starting with a standard model that includes a uniaxial magnetic anisotropy field. Quantum field theory is employed in formulating the problem, and double-time temperature-dependent Green function technique is used to obtain magnon dispersion, whereby random phase approximation is considered to decouple and diagonalize the higher order terms. …”
