Abstract In this paper, we review and discuss the main properties of the time-reversal operator T and its action in classical electromagnetism and in quantum mechanics. In particular, we discuss the relation (and differences) between time-reversal invariance and reciprocity. Introduction In quantum field theory, global and local symmetry invariance play an important and defining role [1]. Some, such as rotation invariance, are continuous symmetries and are described by a Lie group [2, 3] while

Abstract As a hypothetic particle, a sterile neutrino can exist in types of new physics models. In this work by investigating flavor violating semileptonic and leptonic decays of K,D, and B mesons induced by the GeV scale sterile neutrino, we explore its allowed regions in parameter space. Analytically, we derive branching fractions of semileptonic decay \(M^{+}_{h}\to M_{l}^{+}\ell _{1}^{+}\ell _{2}^{-}\) and leptonic decay \(M^{0}\to \ell _{1}^{-}\ell _{2}^{+}\), including the contribution fr

Abstract In this article, we review the recent progress of the scanning tunneling microscopy studies of 1T-TaS2 and 1T-TaSe2 for bulk single crystals and molecular beam epitaxy monolayer films. We focus on how to understand the Mott insulating state in the whole set of materials, even when the stacking order takes effect. Based on this understanding, we discuss tuning the Mott insulator to a metallic state with different techniques, with Mott physics information revealed from the tuning process

Abstract Although the multimessenger detection of the neutron star merger event GW170817 confirmed that mergers are promising sites producing the majority of nature’s heavy elements via the rapid neutron-capture process (r-process), a number of issues related to the production of translead nuclei—the actinides—remain to be answered. In this short review paper, we summarize the general requirements for actinide production in r-process and the impact of nuclear physics inputs. We also discuss rec

Abstract This review introduces the technique of helium ion microscopy along with some unique applications of this technology in the fields of electronics and biology, as performed at the National Institute of Advanced Industrial Science and Technology, Japan, over the last several years. Observations of large-scale integrated circuits, analyses of low-dielectric-constant films with minimal damage, and assessments of copper metal in insulating films are discussed. The special characteristics of

Physicists at the Swinburne University of Technology in Melbourne, Australia, have proposed an exact and solvable model for Fermi polarons that is experimentally realizable in current cold-atom laboratories. The resulting exact many-body solution allowed them to rigorously prove all exact and universal quasiparticle features of Fermi polarons. The behavior of an impurity immersed in a many-body background—i.e., polaron physics—is a long-standing problem in condensed matter physics and many-body
