Dirac fermions in borophene
Baojie Feng, Osamu Sugino, Ro-Ya Liu +14
Honeycomb structures of group IV elements can host massless Dirac fermions with non-trivial Berry phases. Their potential for electronic applications has attracted great interest a…
Pressure dependence of the magnetic ground states in MnP
M. Matsuda, F. Ye, S. E. Dissanayake +11
MnP, a superconductor under pressure, exhibits a ferromagnetic order below TC~290 K followed by a helical order with the spins lying in the ab plane and the helical rotation propag…
Configuration Interaction with Antisymmetrized Geminal Powers
Wataru Uemura, Shusuke Kasamatsu, Osamu Sugino
To avoid the combinatorial computational cost of configuration interaction (CI), we have previously introduced the symmetric tensor decomposition CI (STD-CI) method, where we take…
Electronic Structures of Oxygen-deficient Ta2O5
Yong Yang, Ho-Hyun Nahm, Osamu Sugino +1
We provide a first-principles description of the crystalline and oxygen-deficient Ta2O5 using refined computational methods and models. By performing calculations on a number of ca…
