Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Ice Giant Atmospheric Science
Emma K. Dahl, Shawn Brueshaber, Richard Cosentino +24
This white paper, written in support of NASA's 2023-2032 Planetary Decadal Survey, outlines 10 major questions that focus on the origin, evolution, and current processes that shape…
Fully gapped superconductivity without sign reversal in the topological superconductor PbTaSe
Yue Sun, Shunichiro Kittaka, Toshiro Sakakibara +8
We investigate the superconducting gap function of topological superconductor PbTaSe. Temperature, magnetic field, and three-dimensional (3D) field-angle dependences of the spe…
Wohlleben Effect and Emergent Pi junctions in superconducting Boron doped Diamond thin films
L. Govindaraj, S. Arumugam, R. Thiyagarajan +9
Diamond is an excellent band insulator. However, boron (B) doping is known to induce superconductivity. We present two interesting effects in superconducting B doped diamond (BDD)…
EPIC Simulations of Neptune's Dark Spots Using an Active Cloud Microphysical Model
Nathan Hadland, Ramanakumar Sankar, Raymond Paul LeBeau +1
The Great Dark Spot (GDS-89) observed by Voyager 2 was the first of several large-scale vortices observed on Neptune, the most recent of which was observed in 2018 in the northern…
Anisotropic transport and quantum oscillations in the quasi-one-dimensional TaNiTe5: Evidence for the nontrivial band topology
C. Q. Xu, Y. Liu, P. G. Cai +16
The past decade has witnessed the burgeoning discovery of a variety of topological states of matter with distinct nontrivial band topologies. Thus far, most of materials studied po…
Ultralow Schottky Barriers in hBN-Encapsulated Monolayer WSe Tunnel Field-Effect Transistors
Gaurav Pande, Jyun-Yan Siao, Wei-Liang Chen +7
To explore the potential of field-effect transistors (FETs) based on monolayers of the two-dimensional semiconducting channel(SC) for spintronics, the two most important issues are…
Electron-Electron Interactions in 2D Semiconductor InSe
Arvind Shankar Kumar, Kasun Premasiri, Min Gao +4
Electron-electron interactions (EEIs) in 2D van der Waals structures is one of the topics with high current interest in physics. We report the observation of a negative parabolic m…
Fragmentation modelling of the August 2019 impact on Jupiter
Ramanakumar Sankar, Csaba Palotai, Ricardo Hueso +3
On 7th August 2019, an impact flash lasting s was observed on Jupiter. The video of this event was analysed to obtain the lightcurve and determine the energy release and ini…
Random magnetic anisotropy driven transitions in layered perovskite LaSrCoO
Abdul Ahad, K. Gautam, S. S. Majid +8
Attempts to unravel the nature of magnetic ordering in LaSrCoO (Co), a compound intermediate between antiferromagnetic (AFM) LaCoO (Co) and ferromagnetic…
