Observation of Fundamental Limit of Light Localization
Farbod Shafiei, Massoud R. Masir, Tommaso Orzali +4
In disordered media light can be localized in the spaces between scattering sites which average to an optical mean free path (MFP). However the fundamental question of the smallest…
Magnetic field dependence of the atomic collapse state in graphene
Dean Moldovan, Massoud Ramezani Masir, Francois M. Peeters
Quantum electrodynamics predicts that heavy atoms () will undergo the process of atomic collapse where electrons sink into the positron continuum and a new fam…
Tuning a Circular p-n Junction in Graphene from Quantum Confinement to Optical Guiding
Yuhang Jiang, Jinhai Mao, Dean Moldovan +6
The motion of massless Dirac-electrons in graphene mimics the propagation of photons. This makes it possible to control the charge-carriers with components based on geometrical-opt…
Theory of the Spin Seebeck Effect at a Topological-Insulator/Ferromagnetic-Insulator Interface
Nobuyuki Okuma, Massoud Ramezani Masir, Allan H. MacDonald
The spin-Seebeck effect refers to voltage signals induced in metals by thermally driven spin currents in adjacent magnetic systems. We present a theory of the spin-Seebeck signal i…
Enhanced spin Seebeck effect signal due to spin-momentum locked topological surface states
Zilong Jiang, Cui-Zu Chang, Massoud Ramezani Masir +5
Spin-momentum locking in protected surface states enables efficient electrical detection of magnon decay at a magnetic-insulator/topological-insulator heterojunction. Here we demon…
Realization of a Tunable Artificial Atom at a Supercritically Charged Vacancy in Graphene
Jinhai Mao, Yuhang Jiang, Dean Moldovan +6
The remarkable electronic properties of graphene have fueled the vision of a graphene-based platform for lighter, faster and smarter electronics and computing applications. One of…
