Link between thermodynamic correlation signatures and superconductivity in twisted trilayer graphene
Jesse C. Hoke, Yifan Li, Yuwen Hu +6
Twisted graphene multilayers exhibit strong electronic correlations, which manifest in a range of experimental signatures. Yet how these signatures relate to each other and the mic…
High spatial resolution charge sensing of quantum Hall states
Cheng-Li Chiu, Taige Wang, Ruihua Fan +5
Charge distribution offers a unique fingerprint of important properties of electronic systems, including dielectric response, charge ordering and charge fractionalization. We devel…
Imaging supermoiré relaxation in helical trilayer graphene
Jesse C. Hoke, Yifan Li, Yuwen Hu +5
In twisted van der Waals materials, local atomic relaxation can alter the underlying electronic structure. Characterizing lattice reconstruction and its susceptibility to strain is…
Characterization of two fast-turnaround dry dilution refrigerators for scanning probe microscopy
Mark E. Barber, Yifan Li, Jared Gibson +13
Low-temperature scanning probe microscopes (SPMs) are critical for the study of quantum materials and quantum information science. Due to the rising costs of helium, cryogen-free c…
Direct observation of a magnetic field-induced Wigner crystal
Yen-Chen Tsui, Minhao He, Yuwen Hu +6
Eugene Wigner predicted long ago that when the Coulomb interactions between electrons become much stronger than their kinetic energy, electrons crystallize into a closely packed la…
Fingerprints of Composite Fermion Lambda Levels in Scanning Tunneling Microscopy
Songyang Pu, Ajit C. Balram, Yuwen Hu +6
Composite fermion (CF) is a topological quasiparticle that emerges from a non-perturbative attachment of vortices to electrons in strongly correlated two-dimensional materials. Sim…
High-Resolution Tunneling Spectroscopy of Fractional Quantum Hall States
Yuwen Hu, Yen-Chen Tsui, Minhao He +8
Strong interaction between electrons in two-dimensional systems in the presence of a high magnetic field gives rise to fractional quantum Hall states that host quasiparticles with…
Tuning interactions between spins in a superconductor
Hao Ding, Yuwen Hu, Mallika T. Randeria +5
Novel many-body and topological electronic phases can be created in assemblies of interacting spins coupled to a superconductor, such as one-dimensional topological superconductors…
Structural and magnetic properties of two branches of the Tripod Kagome Lattice family ARESbO (A = Mg, Zn; RE = Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb)
Z. L. Dun, J. Trinh, M. Lee +7
We present a systematic study of the structural and magnetic properties of two branches of the rare earth Tripod Kagome Lattice (TKL) family ARESbO (A = Mg…
Nematic magnetoelastic effect contrasted between Ba(FeCo)As and FeSe
Yuwen Hu, Xiao Ren, Rui Zhang +8
To elucidate the origin of nematic order in Fe-based superconductors, we report a Raman scattering study of lattice dynamics, which quantify the extent of -symmetry breaking,…
Nematic crossover in BaFeAs under uniaxial stress
Xiao Ren, Lian Duan, Yuwen Hu +5
Raman scattering can detect spontaneous point-group symmetry breaking without resorting to single-domain samples. Here we use this technique to study , the par…
Charge density waves and phonon-electron coupling in ZrTe investigated by Raman spectroscopy and first-principles calculations
Yuwen Hu, Feipeng Zheng, Xiao Ren +2
Charge-density-wave (CDW) order has long been interpreted as arising from a Fermi-surface instability in the parent metallic phase. While phonon-electron coupling has been suggeste…
Soft vibrational mode associated with incommensurate orbital order in multiferroic CaMnO
Xinyu Du, Renliang Yuan, Lian Duan +3
We report inelastic light scattering measurements of lattice dynamics related to the incommensurate orbital order in . Below the ordering temperature $T_\mat…
