Times Cited Count：9 Percentile：70.92(Geology)Nuclear waste disposal in geological formations relies on a multi-barrier concept that includes engineered components which in many cases includes a bentonite buffer surrounding waste packages and the host rock. An SKB's (Swedish Nuclear Fuel and Waste Management Co.) Modelling Task Force project facilitated to improve the overall understanding of rock - bentonite interactions, as 11 teams used different conceptualisations and modelling tools to analyse the in-situ experiment at the 
ps Hard Rock Laboratory. The exercise helped identify conceptual uncertainties that led to different assessments of the relative importance of the engineered and natural barrier subsystems and of aspects that need to be better understood to arrive at reliable predictions of bentonite wetting.

Times Cited Count：61 Percentile：95.3(Engineering, Electrical & Electronic)This paper reviews the development of a high-contrast high-intensity petawatt-class Ti:sapphire chirped-pulse amplification (CPA) laser for research on high field science. We discuss in detail the design, performance and characterization of the laser. We also describe the on-going upgrade of the laser system and some applications for the laser in relativistic dominated laser-matter interactions.

Times Cited Count：278 Percentile：98.66(Multidisciplinary Sciences)The nature of the pseudogap phase of cuprate high-temperature superconductors is a major unsolved problem in condensed matter physics. We studied the commencement of the pseudogap state at temperature 
using three different techniques (angle-resolved photoemission spectroscopy, polar Kerr effect, and time-resolved reflectivity) on the same optimally doped Bi2201 crystals. We observed the coincident, abrupt onset at of a particle-hole asymmetric antinodal gap in the electronic spectrum, a Kerr rotation in the reflected light polarization, and a change in the ultrafast relaxational dynamics, consistent with a phase transition. Upon further cooling, spectroscopic signatures of superconductivity begin to grow close to the superconducting transition temperature (
), entangled in an energy-momentum dependent manner with the preexisting pseudogap features, ushering in a ground state with coexisting orders.

We present the on-going upgrade of our high intensity laser system (J-KAREN laser system) in JAEA for higher energy and higher repetition rate operation as an invited talk. We discuss the status and implementation of the upgrade, including system design, evaluation of the components in the system, and the expected performance and characterization of the laser.

We report recent progress on the J-KAREN laser upgrade to realize 10
W/cm
intensity at 0.1 Hz. Our current high-spatiotemporal-quality broadband pulses of over 20 J will be further amplified in the final amplifier.

We present recent progress on the J-KAREN laser upgrade to realize 10 W/cm intensity at 0.1 Hz as an invited talk at CLEO-PR 2015. Our current high-spatiotemporal-quality broadband pulse from the front end is amplified in the final amplifier to over 55 J at this moment. We plan to mention the detailed design, performance and the future prospects.
