Direct observation of the Higgs particle in a superconductor by non-equilibrium Raman scattering
Tomke E. Glier, Sida Tian, Mika Rerrer +12
Even before its role in electroweak symmetry breaking, the Anderson-Higgs mechanism was introduced to explain the Meissner effect in superconductors. Spontaneous symmetry-breaking…
Classification of Lifshitz invariant in multiband superconductors: an application to Leggett modes in the linear response regime in Kagome lattice models
Raigo Nagashima, Sida Tian, Rafael Haenel +2
Multiband superconductors are sources of rich physics arising from multiple order parameters, which show unique collective dynamics including Leggett mode as relative phase oscilla…
Tracing the dynamics of superconducting order via transient third harmonic generation
Min-Jae Kim, Sergey Kovalev, Mattia Udina +13
Ultrafast optical control of quantum systems is an emerging field of physics. In particular, the possibility of light-driven superconductivity with ultrashort laser pulses has attr…
Superconducting diode from flux biased Josephson junction arrays
Rafael Haenel, Oguzhan Can
We propose a realization of the superconducting diode effect in flux biased superconducting circuits of Josephson junctions. So far the observation of the superconducting diode eff…
Incoherent tunneling and topological superconductivity in twisted cuprate bilayers
Rafael Haenel, Tarun Tummuru, Marcel Franz
Twisting two monolayers of a high- cuprate superconductor can engender a chiral topological state with spontaneously broken time reversal symmetry . A crucial ing…
Quench-drive spectroscopy and high-harmonic generation in BCS superconductors
Matteo Puviani, Rafael Haenel, Dirk Manske
In pump-probe spectroscopies, THz pulses are used to quench a system, which is subsequently probed by either a THz or optical pulse. In contrast, third-harmonic generation experime…
Fano interference of the Higgs mode in cuprate high-Tc superconductors
Hao Chu, Sergey Kovalev, Zi Xiao Wang +31
Despite decades of search for the pairing boson in cuprate high-Tc superconductors, its identity still remains debated to date. For this reason, spectroscopic signatures of electro…
Phase signatures in third-harmonic response of Higgs and coexisting modes in superconductors
Lukas Schwarz, Rafael Haenel, Dirk Manske
Third-harmonic generation (THG) experiments on superconductors can be used to investigate collective excitations like the amplitude mode of the order parameter known as Higgs mode.…
Traversable wormhole in coupled SYK models with imbalanced interactions
Rafael Haenel, Sharmistha Sahoo, Timothy H. Hsieh +1
A pair of identical Sachdev-Ye-Kitaev (SYK) models with bilinear coupling forms a quantum dual of a traversable wormhole, with a ground state close to the so called thermofield dou…
Time-resolved optical conductivity and Higgs oscillations in two-band dirty superconductors
Rafael Haenel, Paul Froese, Dirk Manske +1
Recent studies have emphasized the importance of impurity scattering for the optical Higgs response of superconductors. In the dirty limit, an additional paramagnetic coupling of l…
Identification of symmetry-protected topological states on noisy quantum computers
Daniel Azses, Rafael Haenel, Yehuda Naveh +3
Identifying topological properties is a major challenge because, by definition, topological states do not have a local order parameter. While a generic solution to this challenge i…
Zero Bias Conductance Peak in Dirac Semimetal-Superconductor Devices
W. Yu, Rafael Haenel, M. A. Rodriguez +5
Majorana zero modes (MZMs), fundamental building blocks for realizing topological quantum computers, can appear at the interface between a superconductor and a topological material…
Coupled rate-equation hydrodynamic simulation of a Rydberg gas Gaussian ellipsoid: Classical avalanche and evolution to molecular plasma
Rafael Haenel, Edward Grant
An ellipsoidal volume of Rydberg molecules, entrained in a supersonic molecular beam, evolves on a nanosecond timescale to form a strongly coupled ultracold plasma. We present coup…
Dissipative dynamics of atomic and molecular Rydberg gases: Avalanche to ultracold plasma states of strong coupling
M. Aghigh, K. Grant, R. Haenel +8
Not long after metastable xenon was photoionized in a magneto-optical trap, groups in Europe and North America found that similar states of ionized gas evolved spontaneously from s…
Chern insulators for electromagnetic waves in electrical circuit networks
Rafael Haenel, Timothy Branch, Marcel Franz
Periodic networks composed of capacitors and inductors have been demonstrated to possess topological properties with respect to incident electromagnetic waves. Here, we develop an…
Arrested relaxation in an isolated molecular ultracold plasma
R. Haenel, M. Schulz-Weiling, J. Sous +5
Spontaneous avalanche to plasma splits the core of an ellipsoidal Rydberg gas of nitric oxide. Ambipolar expansion first quenches the electron temperature of this core plasma. Then…
