Many-body recombination in insulating cuprates
Derek G. Sahota, Ruixing Liang, M. Dion +4
We study the pump-probe response of three insulating cuprates and develop a model for its recombination kinetics. The dependence on time, fluence, and both pump and probe photon en…
Geometric entanglement in integer quantum Hall states with boundaries
Pierre-Gabriel Rozon, Pierre-Alexandre Bolteau, William Witczak-Krempa
Boundaries constitute a rich playground for quantum many-body systems because they can lead to novel degrees of freedom such as protected boundary states in topological phases. Her…
Seebeck coefficient in low-dimensional fluctuating charge-density-wave systems
M. Mbodji, C. Bourbonnais
We study the role of charge density-wave fluctuations on the temperature dependence of Seebeck coefficient in quasi-one dimensional conductors with a Peierls instability. The descr…
Superconductivity from Coulomb repulsion in three-dimensional quadratic band touching Luttinger semimetals
Serguei Tchoumakov, Louis J. Godbout, William Witczak-Krempa
We study superconductivity driven by screened Coulomb repulsion in three-dimensional Luttinger semimetals with a quadratic band touching and strong spin-orbit coupling. In these se…
Relating bulk to boundary entanglement
Clément Berthiere, William Witczak-Krempa
Quantum many-body systems have a rich structure in the presence of boundaries. We study the groundstates of conformal field theories (CFTs) and Lifshitz field theories in the prese…
Complete optical valley polarization in Weyl semimetals in strong magnetic fields
Simon Bertrand, Jean-Michel Parent, René Côté +1
We present a theory of an optically induced valley polarization in an interacting, time-reversal symmetric Weyl semimetal placed under strong magnetic fields. Because the applicati…
Dielectric and electronic properties of three-dimensional Luttinger semimetals with a quadratic band touching
Serguei Tchoumakov, William Witczak-Krempa
Due to strong spin-orbit coupling, charge carriers in three-dimensional quadratic band touching Luttinger semimetals have non-trivial wavefunctions characterized by a pseudospin of…
Quantum Spin Ice Dynamics in the Dipole-Octupole Pyrochlore Magnet CeZrO
J. Gaudet, E. M. Smith, J. Dudemaine +11
Neutron scattering measurements on the pyrochlore magnet CeZrO reveal an unusual crystal field splitting of its lowest =5/2 multiplet, such that its ground state dou…
