Quantum Oscillations in iron-doped topological insulator Sb2Te3 crystals
Weiyao Zhao, David Cortie, Lei Chen +3
We investigated the magnetotransport properties of Fe-doped topological insulator Sb1.96 Fe0.04Te3 single crystals. With doping, the band structure changes significantly and multip…
Selective Control of Surface Spin Current in Topological Materials based on Pyrite-type OsX2 (X = Se, Te) Crystals
Yuefeng Yin, Michael S. Fuhrer, Nikhil V. Medhekar
Topological materials host robust surface states, which could form the basis for future electronic devices. As such states have spins that are locked to the momentum, they are of p…
Long Range Intrinsic Ferromagnetism in Two Dimensional Materials and Dissipationless Future Technologies
Babar Shabbir, Muhammad Nadeem, Zhigao Dai +4
The inherent susceptibility of low-dimensional materials to thermal fluctuations has long been expected to poses a major challenge to achieving intrinsic long-range ferromagnetic o…
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
E. Estrecho, T. Gao, N. Bobrovska +12
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spon…
Effect of optically-induced potential on the energy of trapped exciton-polaritons below the condensation threshold
M. Pieczarka, M. Boozarjmehr, E. Estrecho +8
Exciton-polaritons (polaritons herein) offer a unique nonlinear platform for studies of collective macroscopic quantum phenomena in a solid state system. Shaping of polariton flow…
Controlled ordering of topological charges in an exciton-polariton chain
T. Gao, O. A. Egorov, E. Estrecho +6
We demonstrate, experimentally and theoretically, controlled loading of an exciton-polariton vortex chain into a 1D array of trapping potentials. Switching between two types of vor…
Controlling spin-orbit interactions in silicon quantum dots using magnetic field direction
Tuomo Tanttu, Bas Hensen, Kok Wai Chan +9
Silicon quantum dots are considered an excellent platform for spin qubits, partly due to their weak spin-orbit interaction. However, the sharp interfaces in the heterostructures in…
Spectroscopic probes of quantum many-body correlations in polariton microcavities
Jesper Levinsen, Francesca Maria Marchetti, Jonathan Keeling +1
We investigate the many-body states of exciton-polaritons that can be observed by pump-probe spectroscopy. Here, a weak-probe `spin-down' polariton is introduced into a coherent st…
Multiband Mechanism for the Sign Reversal of Coulomb Drag Observed in Double Bilayer Graphene Heterostructures
M. Zarenia, A. R. Hamilton, F. M. Peeters +1
Coupled 2D sheets of electrons and holes are predicted to support novel quantum phases. Two experiments of Coulomb drag in electron-hole (e-h) double bilayer graphene (DBLG) have r…
Observation of bosonic condensation in a hybrid monolayer MoSe2-GaAs microcavity
Max Waldherr, Nils Lundt, Martin Klaas +13
Condensation of bosons into a macroscopic quantum state belongs to the most intriguing phenomena in nature. It was first realized in quantum gases of ultra-cold atoms, but more rec…
Variational approach for impurity dynamics at finite temperature
Weizhe Edward Liu, Jesper Levinsen, Meera M. Parish
We present a general variational principle for the dynamics of impurity particles immersed in a quantum-mechanical medium. By working within the Heisenberg picture and constructing…
