Sommario/riassunto |

This book advances understanding of light-induced phase transitions and nonequilibrium orders that occur in a broken-symmetry system. Upon excitation with an intense laser pulse, materials can undergo a nonthermal transition through pathways different from those in equilibrium. The mechanism underlying these photoinduced phase transitions has long been researched, but many details in this ultrafast, non-adiabatic regime still remain to be clarified. The work in this book reveals new insights into this phenomena via investigation of photoinduced melting and recovery of charge density waves (CDWs). Using several time-resolved diffraction and spectroscopic techniques, the author shows that the light-induced melting of a CDW is characterized by dynamical slowing-down, while the restoration of the symmetry-breaking order features two distinct timescales: A fast recovery of the CDW amplitude is followed by a slower re-establishment of phase coherence, the latter of which is dictated by the presence of topological defects in the CDW. Furthermore, after the suppression of the original CDW by photoexcitation, a different, competing CDW transiently emerges, illustrating how a hidden order in equilibrium can be unleashed by a laser pulse. These insights into CDW |

Sommario/riassunto |
|
In a Western world suddenly acutely interested in Islam, one question has been repeatedly heard above the din: where are the Muslim reformers? With this ambitious volume, Tariq Ramadan firmly establishes himself as one of Europe's leading thinkers and one of Islam's most innovative andimportant voices. As the number of Muslims living in the West grows, the question of what it means to be a Western Muslim becomes increasingly important to the futures of both Islam and the West. While the media are focused on radical Islam, Ramadan claims, a silent revolution is sweeping Islamic communities in |
