Finite-momentum Cooper plasmons in superconducting terahertz microcavities
Alex M. Potts, Marios H. Michael, Gunda Kipp +12
The phase mode of a superconductor's order parameter encodes fundamental information about pairing and dissipation, but is typically inaccessible at low frequencies due to the Ande…
First Order Quantum Phase Transition in the Hybrid Metal-Mott Insulator Transition Metal Dichalcogenide 4Hb-TaS2
Abhay Kumar Nayak, Aviram Steinbok, Yotam Roet +8
Coupling together distinct correlated and topologically non-trivial electronic phases of matter can potentially induce novel electronic orders and phase transitions among them. Tra…
Visualizing near-coexistence of massless Dirac electrons and ultra-massive saddle point electrons
Abhay Kumar Nayak, Jonathan Reiner, Hengxin Tan +8
Strong singularities in the electronic density of states amplify correlation effects and play a key role in determining the ordering instabilities in various materials. Recently hi…
On-chip time-domain terahertz spectroscopy of superconducting films below the diffraction limit
Alex Potts, Abhay Nayak, Michael Nagel +5
Free-space time domain THz spectroscopy accesses electrodynamic responses in a frequency regime ideally matched to interacting condensed matter systems. However, THz spectroscopy i…
Chiral to Nematic Crossover in the Superconducting State of 4Hb-TaS
I. Silber, S. Mathimalar, I. Mangel +10
Most superconductors have an isotropic, single component order parameter, and are well described by the BCS theory for superconductivity. Unconventional, multiple components superc…
Visualization of Topological Boundary Modes Manifesting Topological Nodal-Point Superconductivity
Abhay Kumar Nayak, Aviram Steinbok, Yotam Roet +10
The extension of the topological classification of band insulators to topological semimetals gave way to the topology classes of Dirac, Weyl, and nodal line semimetals with their u…
Spectroscopic Visualization of a Robust Electronic Response of Semiconducting Nanowires to Deposition of Superconducting Islands
Jonathan Reiner, Abhay Kumar Nayak, Amit Tulchinsky +9
Following significant progress in the visualization and characterization of Majorana end modes in hybrid systems of semiconducting nanowires and superconducting islands, much atten…
Resolving the Topological Classification of Bismuth with Topological Defects
Abhay Kumar Nayak, Jonathan Reiner, Raquel Queiroz +6
Bulk boundary correspondence in topological materials allows to study their bulk topology through the investigation of their topological boundary modes. However, for classes that s…
Hot Electrons Regain Coherence in Semiconducting Nanowires
Jonathan Reiner, Abhay Kumar Nayak, Nurit Avraham +7
The higher the energy of a particle is above equilibrium the faster it relaxes due to the growing phase-space of available electronic states it can interact with. In the relaxation…
Direct measurements of the magnetocaloric effect in pulsed magnetic fields: The example of the Heusler alloy NiMnIn
M. Ghorbani Zavareh, C. Salazar Mejía, A. K. Nayak +4
We have studied the magnetocaloric effect (MCE) in the shape-memory Heusler alloy NiMnIn by direct measurements in pulsed magnetic fields up to 6 and 20 T. The…
