Resonant Far-Infrared Spectroscopy of Flat-Band Fermions in Magic Angle Graphene
Ayelet J. Uzan-Narovlansky, Ipsita Das, Juan F. Mendez Valderrama +10
Moiré engineering in twisted two-dimensional (2D) materials radically alters low-energy bands, interactions and topological quantum states. Despite extensive studies, optical spect…
Superconductivity from On-Chip Metallization on 2D Topological Chalcogenides
Yanyu Jia, Guo Yu, Tiancheng Song +11
Two-dimensional (2D) transition metal dichalcogenides (TMDs) is a versatile class of quantum materials of interest to various fields including, e.g., nanoelectronics, optical devic…
A Platform for Far-Infrared Spectroscopy of Quantum Materials at Millikelvin Temperatures
Michael Onyszczak, Ayelet J. Uzan, Yue Tang +8
Optical spectroscopy of quantum materials at ultralow temperatures is rarely explored, yet it may provide critical characterizations of quantum phases not possible using other appr…
Evidence for Two Dimensional Anisotropic Luttinger Liquids at Millikelvin Temperatures
Guo Yu, Pengjie Wang, Ayelet J. Uzan +11
While Landau's Fermi liquid theory provides the standard description for two- and three-dimensional (2D/3D) conductors, the physics of interacting one-dimensional (1D) conductors i…
Surface-Confined Two-Dimensional Crystal Growth on a Monolayer
Yanyu Jia, Fang Yuan, Guangming Cheng +12
Conventional vapor deposition or epitaxial growth of two-dimensional (2D) materials and heterostructures is conducted in a large chamber in which masses transport from the source t…
Unconventional Superconducting Quantum Criticality in Monolayer WTe2

Evidence for a Monolayer Excitonic Insulator
Yanyu Jia, Pengjie Wang, Cheng-Li Chiu +19
The interplay between topology and correlations can generate a variety of quantum phases, many of which remain to be explored. Recent advances have identified monolayer WTe2 as a p…
Landau Quantization and Highly Mobile Fermions in an Insulator
Pengjie Wang, Guo Yu, Yanyu Jia +9
In strongly correlated materials, quasiparticle excitations can carry fractional quantum numbers. An intriguing possibility is the formation of fractionalized, charge-neutral fermi…
Piezo-driven sample rotation system with ultra-low electron temperature
Pengjie Wang, Ke Huang, Jian Sun +3
Piezo-driven rotator is convenient for tilted magnetic field experiments due to its precise angle control. However, the rotator itself and the sample mounted on it are difficult to…
Competing ν= 5/2 fractional quantum Hall states in confined geometry
Hailong Fu, Pengjie Wang, Pujia Shan +5
Some theories predict that the filling factor 5/2 fractional quantum Hall state can exhibit non-Abelian statistics, which makes it a candidate for fault-tolerant topological quantu…
