Peking University, Nov. 12, 2013: The discoveries of quantum Hall effect and topological insulators broaden the understanding of fundamental states of quantum matter. In topological view, the quantum matter can be divided into topological trivial and non-trivial materials. The th...

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...
