Peking University, Oct 28, 2015: More than 40 years ago, Robert B. Griffiths predicted that phase transitions can be dramatically changed by disorder effect and in particular the dynamical critical exponent can diverge. In the last 40 years, this theory has been applied to quantu...

Peking University, Oct. 21, 2015: Drug addiction has long been a bothersome problem. Scientists have developed cue-exposure therapies to suppress the patients’ desire to take drugs. The rational of the treatment is to link drug cues with an unfavorable experience, for examp...

Peking University, Sep. 29, 2015: Recently, Professors Du Rui-Rui, and Lin Xi of ICQM, in collaboration with Prof. GáBor Csáthy of Purdue University, discovered a new electronic state called ‘Helical Luttinger liquid’ in InAs/GaSb quantum spin Hall edges...

Peking University, Sep. 25, 2015: The three-dimensional topological Dirac semimetal, as a new type of topological materials, has attracted great attention in condensed matter physics. There, the conduction and valence band touch only at discrete points and disperse linearly along...

Peking University, Sep. 1, 2015: Where did our genes come from? Scientists agree that new genes predominantly develop from a biological process called “gene duplication”. Recent studies have brought in a new idea: new genes might also come from non-coding DNA regions...
