Probing intraband excitations in ZrTe: a high-pressure infrared and transport study
D. Santos-Cottin, M. Padlewski, E. Martino +12
Zirconium pentatetelluride, ZrTe5, shows remarkable sensitivity to hydrostatic pressure. In this work we address the high-pressure transport and optical properties of this compound…
Temperature dependence of photoluminescence lifetime of atomically thin WSe2 layer
Aleksandra Łopion, Mateusz Goryca, Tomasz Smoleński +5
At cryogenic temperatures, the photoluminescence spectrum of monolayer WSe2features a num-ber of lines related to the recombination of so-called localized excitons. The intensity o…
Charge density wave sliding driven by an interplay of conventional and Hall voltages in NbSe microbridges

Collective charge-density wave (CDW) transport was measured under a high magnetic field in NbSe microbridges which have been cut transversely and at an angle to the chains' dir…
Magneto-optics of a Weyl semimetal beyond the conical band approximation: the case study of TaP
S. Polatkan, M. O. Goerbig, J. Wyzula +10
Landau-level spectroscopy, the optical analysis of electrons in materials subject to a strong magnetic field, is a versatile probe of the electronic band structure and has been suc…
Spin-lattice coupling in a ferrimagnetic spinel: The exotic - phase diagram of MnCrS up to 110 T
A. Miyata, H. Suwa, T. Nomura +10
In antiferromagnets, the interplay of spin frustration and spin-lattice coupling has been extensively studied as the source of complex spin patterns and exotic magnetism. Here, we…
Electronic phase separation in topological surface states of rhombohedral graphite
Yanmeng Shi, Shuigang Xu, Yaping Yang +15
Of the two stable forms of graphite, hexagonal (HG) and rhombohedral (RG), the former is more common and has been studied extensively. RG is less stable, which so far precluded its…
Pd NMR and NQR study of the cubic heavy fermion system CePdSi
Ivan Jakovac, Mladen Horvatić, Eike F. Schwier +5
We report Pd NMR and NQR measurements on a single crystal of CePdSi, where antiferroquadrupolar and antiferromagnetic orders develop at low temperature. From…
Dark trions govern the temperature-dependent optical absorption and emission of doped atomically thin semiconductors
Ashish Arora, Nils Kolja Wessling, Thorsten Deilmann +7
We perform absorption and photoluminescence spectroscopy of trions in hBN-encapsulated WSe, WS, MoSe, and MoS monolayers, depending on temperature. The different tr…
Laser-produced magnetic-Rayleigh-Taylor unstable plasma slabs in a 20 T magnetic field
B. Khiar, G. Revet, A. Ciardi +15
Magnetized laser-produced plasmas are central to many novel laboratory astrophysics and inertial confinement fusion studies, as well as in industrial applications. Here we provide…
Magnon bound states vs. anyonic Majorana excitations in the Kitaev honeycomb magnet -RuCl
Dirk Wulferding, Youngsu Choi, Seung-Hwan Do +5
The pure Kitaev honeycomb model harbors a quantum spin liquid in zero magnetic fields, while applying finite magnetic fields induces a topological spin liquid with non-Abelian anyo…
Field-angular Dependence of Pairing Interaction in URhGe: Comparison with UCoGe
Yo Tokunaga, Dai Aoki, Hadrien Mayaffre +8
The field-angular dependence of Co-NMR spin-lattice relaxation rate 1/T1 has been measured for a 10% Co-doped single crystal of URhGe. The experiment revealed that spin fluctuation…
Exciton-polaritons in multilayer WSe in a planar microcavity
M. Król, K. Rechcińska, K. Nogajewski +10
Due to high binding energy and oscillator strength, excitons in thin flakes of transition metal dichalcogenides constitute a perfect foundation for realizing a strongly coupled lig…
Hidden magnetism at the pseudogap critical point of a high temperature superconductor
Mehdi Frachet, Igor Vinograd, Rui Zhou +17
The mysterious pseudogap phase of cuprate superconductors ends at a critical hole doping level p* but the nature of the ground state below p* is still debated. Here, we show that t…
Phase Transition Induced Carrier Mass Enhancement in 2D Ruddlesden-Popper Perovskites
Michal Baranowski, Szymon J. Zelewski, Mikael Kepenekian +10
There is a variety of possible ways to tune the optical properties of 2D perovskites, though the mutual dependence between different tuning parameters hinders our fundamental under…
Giant Fine Structure Splitting of the Bright Exciton in a Bulk MAPbBr Single Crystal
Michal Baranowski, Krzysztof Galkowski, Alessandro Surrente +13
Exciton fine structure splitting in semiconductors reflects the underlying symmetry of the crystal and quantum confinement. Since the latter factor strongly enhances the exchange i…
