Quantization through dissipation: impurity states and the optical quantum Hall effect
Zhenisbek Tagay, Ahmed Abouelkomsan, Yugo Onishi +4
The integer quantum Hall effect remains the most paradigmatic and remarkable example of exact quantization in condensed matter physics. Its Hall conductivity is fixed to $…
Reconciling strange metal transport in CeCoIn through the difference of optical and cyclotron effective masses
Jingyuan Wang, Zhenisbek Tagay, Liyu Shi +10
The strange metal behavior in cuprate superconductors - characterized by linear in temperature resistivity and anomalous Hall transport - stands in stark contrast to the expectatio…
Terahertz range polarization rotation in the candidate time-reversal symmetry breaking superconductor BiNi
Ralph Romero, Zhenisbek Tagay, Jiahao Liang +3
Here we report the observation of time-reversal symmetry (TRS) breaking superconductivity in a BiNi bilayer using terahertz (THz) polarimetry. Leveraging a novel high-precision THz…
Phase Diagram and Spectroscopic Signatures of a Supersolid in Quantum Ising Magnet KCo(SeO)
Tong Chen, Alireza Ghasemi, Junyi Zhang +17
A supersolid is a quantum-entangled state of matter exhibiting the dual characteristics of superfluidity and solidity. Theory predicts that hard-core bosons with repulsive interact…
Electrodynamics of the quantum anomalous Hall state in a magnetically doped topological insulator
Zhenisbek Tagay, Hee Taek Yi, Deepti Jain +2
Magnetically doped topological insulators have been extensively studied over the past decade as a material platform to exhibit quantum anomalous Hall effect. Most material realizat…
High-precision measurements of terahertz polarization states with a fiber coupled time-domain THz spectrometer
Zhenisbek Tagay, Ralph Romero, N. P. Armitage
We present a new method for high precision measurements of polarization rotation in the frequency range from 0.2 to 2.2 THz using a fiber coupled time-domain THz spectrometer. A fr…
Low energy electrodynamics and a hidden Fermi liquid in the heavy-fermion CeCoIn
L. Y. Shi, Zhenisbek Tagay, Jiahao Liang +6
We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn. Below the 40 K Kondo coherence temperature, a narrow Drude-like peak…
BCS -wave behavior in the THz electrodynamic response of electron-doped cuprate superconductors
Zhenisbek Tagay, Fahad Mahmood, Anaelle Legros +3
Although cuprate superconductors have been intensively studied for the past decades, there is no consensus regarding the microscopic origin of their superconductivity. In this work…
