Autor: Luca Planat, Arpit Ranadive, Rémy Dassonneville, Javier Puertas Martínez, Sébastien Léger, Cécile Naud, Olivier Buisson, Wiebke Hasch-Guichard, Denis M. Basko, Nicolas Roch

Publikováno v: Physical Review X, Vol 10, Iss 2, p 021021 (2020)

A microwave amplifier combining noise performances as close as possible to the quantum limit with large bandwidth and high saturation power is highly desirable for many solid-state quantum technologies. Here, we introduce a new traveling-wave paramet

Autor: Sébastien Léger, Théo Sépulcre, Dorian Fraudet, Olivier Buisson, Cécile Naud, Wiebke Hasch-Guichard, Serge Florens, Izak Snyman, Denis M. Basko, Nicolas Roch

Publikováno v: SciPost Physics, Vol 14, Iss 5, p 130 (2023)

Quantum impurities are ubiquitous in condensed matter physics and constitute the most stripped-down realization of many-body problems. While measuring their finite-frequency response could give access to key characteristics such as excitations spectr

Signature of resonant modes in radiative heat current noise spectrum

Autor: Jonathan L. Wise, Nathan Roubinowitz, Wolfgang Belzig, Denis M. Basko

Publikováno v: Physical Review B. 106

Radiative heat transfer between bodies is often dominated by a narrow resonance in the transmission, e.~g. due to a cavity mode or a surface excitation. However, this resonant character is not visible in the average heat current. Here, we show that t

Superradiant quantum phase transition for Landau polaritons with Rashba and Zeeman couplings

Autor: Guillaume Manzanares, Thierry Champel, Denis M. Basko, Pierre Nataf

Publikováno v: Physical Review B. 105

We develop a theory of cavity quantum electrodynamics for a two-dimensional electron gas in the presence of Rashba spin-orbit and Zeeman couplings and perpendicular magnetic field, coupled to a spatially nonuniform quantum photon field. We show that

Comment on 'Inconsistency of the conventional theory of superconductivity' by Hirsch J. E

Autor: Robert S. Whitney, Denis M. Basko

EPL-Europhysics Letters, European Physical Society/EDP Sciences/Società Italiana di Fisica/IOP Publishing, 2020, 131 (4), pp.47002. ⟨10.1209/0295-5075/131/47002⟩

J. E. Hirsch [EPL 130 (2020) 17006] claimed an inconsistency between thermodynamics and the theory of superconductivity. We argue that he overlooked a crucial term which determines the supercurrent dynamics and ensures energy conservation by providin

We perform a theoretical study of the near-field heat transfer between two atomically thin metallic layers, isolated galvanically but coupled by the Coulomb interaction, within the framework of fluctuational electrodynamics in the Coulomb limit. We c
