CONSEQUENCES OF CARTOONS. “In solid state physics described by quantum statistical mechanics, another typical non-applicability domain of particle pictures can also be found in the well-known phenomena of phase transitions caused by the instability between two stable thermodynamic phases with different particle pictures, through which the same physical system undergoes drastic changes in material configurations.” https://lnkd.in/dpsM58Ep View in LinkedIn

CARTOON PICTURE. “Since the above simple-minded interpretation of quantum fields in terms of creation and annihilation operators is meaningful only for free fields without interactions, the validity of this vocabulary is at most for the asymptotic fields and states which describe quantum fields approximately only in the remote past or future regimes, respectively, before or after the actual scattering processes.” https://lnkd.in/dpsM58Ep View in LinkedIn

CONSEQUENCES OF FORGETTING. “While this language is very convenient in treating many-body problems in both contexts of relativistic particle physics and of non-relativistic solid state physics, its serious pitfall lies in its “forgetfulness” about the strict restriction on its applicability in physical nature!” https://lnkd.in/dpsM58Ep View in LinkedIn

REVIVING FORGOTTEN PHYSICS. “The reason for introducing the new formulation will be explained in the final section from the viewpoint to exhibit the contrast between free and interacting quantum fields in regard to their energy-momentum supports which are seldom touched upon (or forgotten) in the common physical discussions about quantum fields.” https://lnkd.in/dpsM58Ep View in LinkedIn

APPLICATIONS. Dressed photons have practical applications. “They are applications of dressed photons to novel optical functional devices, nano-fabrication technologies, energy conversion technologies, and photon breeding devices.” They represent a new paradigm in this field of physics. https://lnkd.in/dpsM58Ep View in LinkedIn

THE SENIOR AUTHOR, Hiroyuki Ochiai, is a mathematician associated with Kyushu University, and has published on diverse mathematical issues including tiling, lie symmetry fractals and other very interesting topics. https://lnkd.in/d2_j9__K View in LinkedIn

THE LEAD AUTHOR, Hirofumi Sakuma works at the Research Origin for Dressed Photon, at the Yokohama Technology Center, NICHA Corporation, Yokohama-shi in Japan. His publications all focus on dressed photons. " " https://lnkd.in/deurYDNK View in LinkedIn

FRAGMENT FROM NATURE focuses on some unusual Japanese research on photons, dressed photons and soft photons. While we still have a poor understanding of the nature of light, this research proves that it is not necessary to fully understand a system in order to exploit it for practical purposes.

“FREE PROTONS occur occasionally on Earth: thunderstorms can produce protons with energies of up to several tens of MeV. At sufficiently low temperatures and kinetic energies, free protons will bind to electrons. However, the character of such bound protons does not change, and they remain protons.” https://en.m.wikipedia.org/wiki/Proton View in LinkedIn
