Photon Correlation Spectroscopy as a Probe of Critical Fluctuations in Correlated Electron Systems
Natasha Kiper, Bertrand Evrard, Yuya Shimazaki +5
Characterizing phase transitions between correlated electronic phases, extracting their critical exponents, and identifying their universality class are of central interest in many…
High-temperature helical edge states in BiSbTeSe/graphene van der Waals heterostructure
Yoichi Tanabe, Ngoc Han Tu, Ming-Chun Jiang +11
Van der Waals heterostructures have been used to tailor atomic layers into various artificial materials through interactions at heterointerfaces. The interplay between the band gap…
Optical sensing of fractional quantum Hall effect in graphene
A. Popert, Y. Shimazaki, M. Kroner +4
Graphene and its van der Waals (vdW) heterostructures provide a unique and versatile playground for explorations of strongly correlated electronic phases, ranging from unconvention…
Observation of electrically tunable Feshbach resonances in twisted bilayer semiconductors
Ido Schwartz, Yuya Shimazaki, Clemens Kuhlenkamp +4
Moire superlattices in twisted transition metal dichalcogenide bilayers have emerged as a rich platform for exploring strong correlations using optical spectroscopy. Despite observ…
Observation of Wigner crystal of electrons in a monolayer semiconductor
T. Smoleński, P. E. Dolgirev, C. Kuhlenkamp +9
When the Coulomb repulsion between electrons dominates over their kinetic energy, electrons in two dimensional systems were predicted to spontaneously break continuous translation…
Optical signatures of charge order in a Mott-Wigner state
Yuya Shimazaki, Clemens Kuhlenkamp, Ido Schwartz +7
The elementary optical excitations in two dimensional semiconductors hosting itinerant electrons are attractive and repulsive polarons -- excitons that are dynamically screened by…
Moiré superlattice in a MoSe/hBN/MoSe heterostructure: from coherent coupling of inter- and intra-layer excitons to correlated Mott-like states of electrons
Yuya Shimazaki, Ido Schwartz, Kenji Watanabe +3
Two dimensional materials and their heterostructures constitute a promising platform to study correlated electronic states as well as many body physics of excitons. Here, we presen…
Spin-valley Hall transport induced by spontaneous symmetry breaking in half-filled zero Landau level of bilayer graphene
Miuko Tanaka, Yuya Shimazaki, Ivan Valerievich Borzenets +4
Intrinsic Hall conductivity, emerging when chiral symmetry is broken, is at the heart of future low energy consumption devices because it can generate non-dissipative charge neutra…
Interacting Polaron-Polaritons
Li Bing Tan, Ovidiu Cotlet, Andrea Bergschneider +5
Two dimensional semiconductors provide an ideal platform for exploration of linear exciton and polariton physics, primarily due to large exciton binding energy and strong light-mat…
Shubnikov-de Haas oscillations in optical conductivity of monolayer MoSe
T. Smoleński, O. Cotlet, A. Popert +8
We report polarization-resolved resonant reflection spectroscopy of a charge-tunable atomically-thin valley semiconductor hosting tightly bound excitons coupled to a dilute system…
Landau level evolution driven by band hybridization in mirror symmetry broken ABA-stacked trilayer graphene
Yuya Shimazaki, Toru Yoshizawa, Ivan V. Borzenets +7
Layer stacking and crystal lattice symmetry play important roles in the band structure and the Landau levels of multilayer graphene. ABA-stacked trilayer graphene possesses mirror-…
High Efficiency CVD Graphene-lead (Pb) Cooper Pair Splitter
I. V. Borzenets, Y. Shimazaki, G. F. Jones +4
We demonstrate high efficiency Cooper pair splitting in a graphene-based device. We utilize a true Y-shape design effectively placing the splitting channels closer together: graphe…
Generation and detection of pure valley current by electrically induced Berry curvature in bilayer graphene
Yuya Shimazaki, Michihisa Yamamoto, Ivan V. Borzenets +3
Valley is a useful degree of freedom for non-dissipative electronics since valley current that can flow even in an insulating material does not accompany electronic current. We use…
