Conceptual Metaphor of Time in Transient Days by Zhu Ziqing: a case study

This paper tries to explore the conceptual metaphor of time in Transient Days, an essay about time written by a famous Chinese writer, Zhu Ziqing, to address such problems as (1) Is there any linguistic evidence in Transient Days supporting the universality of the conceptual metaphor models (TIME IS A THING/ENTITY, TIME PASSING IS MOTION (THROUGHN SPACE) and TIME IS MONEY (A VALUABLE COMMODITY/LIMITED RESOURCE)) established by the previous studies?; and (2) Concerning the TIME PASSING IS MOTION model, are there more TIME PASSING IS A MOVING OBJECT than TIME PASSING IS MOTION OVER A LANDSCAPE metaphors in it? Key words: Conceptual metaphor, time, Transient Days Résumé: Le présent article tente d’explorer la métaphore du temps dans les Jours transitoires, un essai sur le temps écrit par un écrivain célèbre chinois Zhu Ziqing, pour poser des problèmes, tels que : (1) Est-ce qu’il y a des preuves linguistiques dans les Jours transitoires supportant l’universalité des modèles de métaphore conceptuelle ( Le temps est une chose/entité, l’écoulement du temps est un mouvement (à travers l’espace) et le temps est l’argent ( un article d’usage valable/ une ressource limitée) établis par les études précédentes ? (2) En ce qui concerne le modèle que l’écoulement du temps est un mouvement, est-ce qu’il y a plus de métaphores sur le fait que l’écoulement du temps est un objet mouvant que sur le fait que l’écoulement du temps est un mouvement au dessus d’un paysage ? Mots-Clés: métaphore conceptuelle, temps, Jours transitoires 摘 要：本文通過分析著名中國作家朱自清的散文《匆匆》中關於時間的概念隱喻來解決以下兩個問題：（1）《匆匆》中是否有語言事實支援在以往研究中建立的時間概念隱喻的模型：時間是一個事物/實體，時間流逝是移動（穿過空間），時間是金錢（有價值的商品/有限的資源）；（2）鑒於時間流逝是移動這一概念隱喻模型之下又可分為兩個小模型：時間流逝是一個移動的物體和時間流逝是穿過空間的移動，本文同時探究在《匆匆》中哪個小模型的時間隱喻更多一些？ 關鍵詞：概念隱喻；時間；《匆匆

Blue Phosphorene Oxide: Strain-tunable Quantum Phase Transitions and Novel 2D Emergent Fermions

Tunable quantum phase transitions and novel emergent fermions in solid state materials are fascinating subjects of research. Here, we propose a new stable two-dimensional (2D) material, the blue phosphorene oxide (BPO), which exhibits both. Based on first-principles calculations, we show that its equilibrium state is a narrow-bandgap semiconductor with three bands at low energy. Remarkably, a moderate strain can drive a semiconductor-to-semimetal quantum phase transition in BPO. At the critical transition point, the three bands cross at a single point at Fermi level, around which the quasiparticles are a novel type of 2D pseudospin-1 fermions. Going beyond the transition, the system becomes a symmetry-protected semimetal, for which the conduction and valence bands touch quadratically at a single Fermi point that is protected by symmetry, and the low-energy quasiparticles become another novel type of 2D double Weyl fermions. We construct effective models characterizing the phase transition and these novel emergent fermions, and we point out several exotic effects, including super Klein tunneling, supercollimation, and universal optical absorbance. Our result reveals BPO as an intriguing platform for the exploration of fundamental properties of quantum phase transitions and novel emergent fermions, and also suggests its great potential in nanoscale device applications.Comment: 23 pages, 5 figure
