Weakly spin-dependent band structures of antiferromagnetic perovskite LaMO (M = Cr, Mn, Fe)
Takuya Okugawa, Kaoru Ohno, Yusuke Noda +1
We investigate spin-dependent electronic states of antiferromagnetic (AFM) lanthanum chromite (LaCrO), lanthanum manganite (LaMnO), and lanthanum ferrite (LaFeO) using…
Dynamical instability in a Floquet-Driven Dissipative System
Takuya Okugawa, Jens Paaske, Martin Eckstein +3
We analyse the magnon spectrum and distribution function of the antiferromagnetic phase of the Floquet-driven Hubbard model. Above a critical drive strength, we find a dynamical in…
Floquet Engineering Magnetism and Superconductivity in the Square-Lattice Hubbard Model
Jan-Niklas Herre, Takuya Okugawa, Ammon Fischer +2
We study the interplay of magnetic order and superconductivity in the square-lattice Hubbard model under periodic driving with circularly polarized light. Formulating diagrammatic…
Cavity-altered superconductivity
Itai Keren, Tatiana A. Webb, Shuai Zhang +30
Is it feasible to alter the ground state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions, experimental realizations of…
Imaging van Hove Singularity Heterogeneity in Overdoped Graphene
Raymond Blackwell, Zengyi Du, Takuya Okugawa +7
Tuning the chemical potential of a solid to the vicinity of a van Hove singularity (vHS) is a well-established route to discovering emergent quantum phases. In monolayer graphene,…
Correlated disorder induced anomalous transport in magnetically doped topological insulators
Takuya Okugawa, Tanay Nag, Dante M. Kennes
We examine the transport properties of magnetically doped topological insulator (TI) thin films subject to correlated non-magnetic disorder. For the disorder we choose a quasi-peri…
Anti-Poiseuille Flow: Increased Vortex Velocity at Superconductor Edges
T. Okugawa, A. Benyamini, A. J. Millis +1
Using the time-dependent Ginzburg Landau equations we study vortex motion driven by an applied current in two dimensional superconductors in the presence of a physical boundary. At…
Vortex control in superconducting Corbino geometry networks
T. Okugawa, S. Park, P. Recher +1
In superconductors, vortices induced by a magnetic field are nucleated randomly due to some random fluctuations or pinned by impurities or boundaries, impeding the development of v…
Topological Phase Transitions Induced by Disorder in Magnetically Doped (Bi, Sb)Te Thin Films
Takuya Okugawa, Peizhe Tang, Angel Rubio +1
We study disorder induced topological phase transitions in magnetically doped (Bi, Sb)Te thin films, by using large scale transport simulations of the conductance through a…
Discovering new two-dimensional topological insulators from computational screening
Thomas Olsen, Erik Andersen, Takuya Okugawa +3
We have performed a computational screening of topological two-dimensional (2D) materials from the Computational 2D Materials Database (C2DB) employing density functional theory. A…
