Metallisation of the Mott Insulator CaRuO using Electric Double-Layer Gating

Tatsuhiro Sakami, Hiroki Ogura, Akihiro Ino +3

To verify whether the Mott insulator Ca2RuO4 can be switched by applying electric-field alone, regardless of current flow, we employ metallisation using electric double-layer gatin…

Challenges in extracting nonlinear current-induced phenomena in Ca2RuO4

Giordano Mattoni, Kazumi Fukushima, Shingo Yonezawa +2

An appealing direction to change the properties of strongly correlated materials is to induce nonequilibrium steady states by the application of a direct current. While access to t…

Unique Itinerant Ferromagnetism in 4d-electron System Ca2RuO4

Fumihiko Nakamura, Hiroki Ogura, Tatsuhiro Sakami +1

We have studied the magnetic properties of pressure-induced ferromagnet Ca2RuO4 to reveal the uniqueness of the 4d-electron ferromagnetism in the quasi-two-dimensional conductor. T…

Impacts of the direct URCA and Superfluidity inside a Neutron Star on Type-I X-Ray Bursts and X-Ray Superbursts

Akira Dohi, Nobuya Nishimura, Hajime Sotani +4

We investigate the impacts of neutrino cooling mechanism inside the neutron star (NS) core on the light curves of type-I X-ray bursts and X-ray superbursts. From several observatio…

Keldysh space control of charge dynamics in a strongly driven Mott insulator

Xinwei Li, Honglie Ning, Omar Mehio +7

The fate of a Mott insulator under strong low frequency optical driving conditions is a fundamental problem in quantum many-body dynamics. Using ultrafast broadband optical spectro…

Cooling of Isolated Neutron Stars with Pion Condensation: Possible Fast Cooling in a Low-Symmetry-Energy Model

Akira Dohi, Helei Liu, Tsuneo Noda +1

We studied thermal evolution of isolated neutron stars (NSs) including the pion condensation core, with an emphasis on the stiffness of equation of state (EOS). Many temperature ob…
