Sir Anthony James Leggett (born 26 March 1938) is a British–American theoretical physicist and professor emeritus at the University of Illinois Urbana-Champaign (UIUC). [5] Leggett is widely recognised as a world leader in the theory of low-temperature physics , and his pioneering work on superfluidity was recognised by the 2003 Nobel Prize ...
The Leggett–Garg inequality, [1] named for Anthony James Leggett and Anupam Garg, is a mathematical inequality fulfilled by all macrorealistic physical theories.Here, macrorealism (macroscopic realism) is a classical worldview defined by the conjunction of two postulates, of which the second has actually nothing to do with “macro-realism”: [1]
In physics, the Leggett inequalities, [1] named for Anthony James Leggett, who derived them, are a related pair of mathematical expressions concerning the correlations of properties of entangled particles. (As published by Leggett, the inequalities were exemplified in terms of relative angles of elliptical and linear polarizations.)
Theory of Change (ToC) is a multi-purpose tool that can be applied for the purpose of planning, managing, monitoring, and evaluating research, especially change-oriented research (e.g., research-for-development, transdisciplinary research, sustainability science). As in other applications, a research ToC describes the causal relationships ...
A specific class of non-local theories suggested by Anthony Leggett is ruled out. Based on this, the authors conclude that any possible non-local hidden-variable theory consistent with quantum mechanics must be highly counterintuitive. [22] [23]
Many prominent scientists studied under Ter Haar, including Anthony Leggett, winner of the Nobel Prize in Physics in 2003, and Deng Jiaxian, one of the leading scientists and founders of Chinese nuclear weapons programs.
The Institute for Condensed Matter Theory (ICMT) is an institute for the research of condensed matter theory hosted by and located at the University of Illinois at Urbana-Champaign. ICMT was founded in 2007. The first director of the institute was Paul Goldbart who was followed by Eduardo Fradkin. The chief scientist is Nobel laureate Anthony ...
In 1981, Amir Caldeira and Anthony J. Leggett proposed a simple model to study in detail the way dissipation arises from a quantum point of view. [2] It describes a quantum particle in one dimension coupled to a bath.
