Flat-band formation and chiral superconductivity in driven topological insulators
Suman Jyoti De, Leo Goutte, Kartiek Agarwal +1
We demonstrate that circularly polarized light can be used to Floquet-engineer nearly flat or Mexican-hat like electronic bands on the surface of three-dimensional topological insu…
Analytic gradients for low-rank quantum optimal control
Leo Goutte, Vincenzo Savona
We introduce low-rank optimal control (LROC), a method for designing control pulses in open quantum systems whose full density-matrix simulation is prohibitively expensive. The met…
Low-rank optimal control of quantum devices
Leo Goutte, Vincenzo Savona
We demonstrate that the control protocols of quantum information devices can be simulated by assuming a low-rank ansatz for the density matrix. The rationale underlying this assump…
Tunnelling theory of Weyl semimetals in proximity to a metallic band
L. Goutte, T. Pereg-Barnea
We study the effects of tunnelling on the band structure and Fermi arc of a time-reversal broken Weyl semimetal (WSM). When coupled to a non-magnetic parabolic band, the WSM's chir…
Surface theory of a second-order topological insulator beyond the Dirac approximation
B. A. Levitan, L. Goutte, T. Pereg-Barnea
We study the surface states and chiral hinge states of a 3D second-order topological insulator in the presence of an external magnetic gauge field. Surfaces pierced by flux host La…
