Hace 2 días · Feynman provided a quantum-mechanical explanation for the Soviet physicist Lev Landau's theory of superfluidity. Applying the Schrödinger equation to the question showed that the superfluid was displaying quantum mechanical behavior observable on a macroscopic scale.
16 de may. de 2024 · 列夫·达维多维奇·朗道 （俄語： Лев Дави́дович Ланда́у ，罗马化： Lev Davidovich Landau ，1908年1月22日—1968年4月1日），前 蘇聯 著名 物理學家 ， 凝聚态物理学 的奠基人，苏联科学领军人之一 [3] ，同时擅长理论物理多个分支领域，在 理論物理 裡多個領域都有重大貢獻。 以惊人的物理直觉、杰出的物理研究成果、扎实的基本功、精炼的著作风格和严格的性格而为人熟知。 他由於「關於凝聚態物質的開創性理論，特別是 液氦 」獲得1962年的 諾貝爾物理學獎 [4] 。 他反对苏共独裁，并曾因反革命罪入狱。 1962年，仍活跃于研究前沿的朗道发生严重车祸，工作能力受损，身体状况大不如前，6年后去世。
9 de may. de 2024 · In the early 1950s Feynman provided a quantum-mechanical explanation for the Soviet physicist Lev D. Landau’s theory of superfluidity—i.e., the strange, frictionless behaviour of liquid helium at temperatures near absolute zero.
Hace 5 días · That year, he befriended Russian physicists George Gamow and Lev Landau. Teller's lifelong friendship with a Czech physicist, George Placzek, was also very important for his scientific and philosophical development.

Hace 3 días · In 1932 an analytic solution to the problem of calculating adiabatic transition probabilities was published separately by Lev Landau and Clarence Zener, for the special case of a linearly changing perturbation in which the time-varying component does not couple the relevant states (hence the coupling in the diabatic Hamiltonian ...
Hace 3 días · Lev Davidovich Landau (1908--1968) was a Soviet/Russian physicist who made fundamental contributions to many areas of theoretical physics. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K.
