2015 Nobel laureate, Prof. Takaaki Kajita, visited NCTS and Institute of Astronomy for collaboration on KAGRA project. Prof. Kajita was awarded 2015 Nobel price in physics for his contribution in observing neutrino oscillation, which indicates that neutrino has a finite mass. This observation shows that the standard model in high energy physics is not complete and may lead to further observation of new physics. Recently, Prof. Kajita also leads a new group (Large-scale Cryogenic Gravitational Wave Telescope Project) in Japan to observe gravitational waves, which is another important and fundamental subject in physics. His visit is to join a workshop with Institute of Astronomy of NTHU for the collaboration in this new project.Read More Prof. Chung-Yu Mou, Prof. Chung-Hou Chung (TG8) and collaborators published their research in Phys. Rev. Lett. on April 29, 2016 on theoretical realization of fermionic finite-temperature Dirac points as critical points separating two topological phases in a Kondo lattice. The underlying Dirac point is central to the profound physics manifested in a wide class of materials. However, it is often difficult to drive a system with Dirac points across the massless fermionic critical point. Here by exploiting screening of local moments under spin-orbit interactions in a Kondo lattice, they show that below the Kondo temperature, the Kondo lattice undergoes a topological transition from a strong topological insulator (STI) to a weak topological insulator (WTI) at a finite temperature TD. At&n...Read More Prof. Kingman Cheung (Distinguished Center Scientist of NCTS, and professor of NTHU physics) received the Outstanding Research Award of the MoST for the year 2015. His research aims for solving the most fundamental questions of our Universe: the origin of mass, evolution of the Universe, grand unification of forces, dark matter, etc. Through solving these questions to understand the existence of humans and evolution of the Universe. One of his main focus in the past few years has been on the Higgs boson, which is deeply related to the electroweak symmetry breaking and origin of mass.
Since the Higgs boson was discovered in July 2012 and studied thoroughly until the upgrade at the end of 2014, Kingman, Jae-Sik Lee of Korea and Po-Yan Tseng started a Higgs-precision rese...Read More The study of the spin Hall effect in graphene is an active field of research, but its experimental realization is proven to be difficult due to the inherently weak intrinsic spin-orbit interaction. Thus, one needs to rely on extrinsic spin-orbit scattering to be able to probe this effect in graphene.
Prof. Miguel Cazalilla (Distinguished Center Scientist of NCTS and professor in NTHU) and his students/collaborators have reported some progress in this direction. They predict that adatoms on graphene can induce an anisotropic Rashba spin-orbit coupling, and the degree of anisotropy has a noticeable effect on the energy dependence of the spin Hall angle. They study the effect of anisotropy of the Rashba coupling on the extrinsic spin Hall effect due to spin-orbit active adatoms on gr...Read More Magneto-optical Kerr effect, discovered by J. Kerr in 1877, refers to the fact that when a linear polarized light beam hits a magnetic material the polarization plane of the reflected light beams rotates. Nowadays Magneto-optical Kerr effect is widely used as a powerful probe of the electronic and magnetic properties of materials, such as domain wall, surface plasma resonance, magnetic anisotropy and topological insulator. However, magneto-optical Kerr effect has been found only in magnetic materials with nonzero magnetization such asferromagnets and ferrimagnets. Using first-principles density functional theory, Guang-Yu Guo (a DCS of the NCTS) and his co-workers  recently demonstrate for the first time large magneto-optical Kerr effect in high-temperature noncollinearantiferroma...Read More

Congratulation to the LIGO Scientific Collaboration, and to Professor Shiuh Chao (趙 煦）and his team of the National Tsing Hua University for the discovery.
The gravitational wave was detected on September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory. Based on the observation, scientists estimated that the event was created the collision of a pair of blackholes, of masses about 29 and 36 times the solar mass, and the event took place 1.3 billion years ago.
