Directional Manipulation of a Staggered Charge Density Wave and Kondo Resonance in UTe2
Nileema Sharma, Fangjun Cheng, Hyeok Jun Yang +7
UTe2 is a rare example of a correlated quantum material in which unconventional density wave orders, Kondo physics, spin-triplet pairing, and reentrant superconductivity coexist wi…
Intrinsic Nernst Effect from Berry Curvature in Superconductors
Tzu-Chi Hsieh, Cong Xiao, Yi-Ting Hsu
The Nernst effect in superconductors is typically linked to fluctuating Cooper pairs above or vortex motion below . We show instead that Berry curvature of Bogoliubov qu…
Displacement-Field-Driven Transition between Superconductivity and Valley Ferromagnetism in Transition Metal Dichalcogenides
Hyeok-Jun Yang, Yi-Ting Hsu
Recent experiments have observed transitions between superconductivity and correlated magnetism in twisted bilayer WSe near van-Hove fillings, driven by the displacement field…
g-Factor Enhanced Upper Critical Field in Superconducting PdTe2 due to Quantum Confinement
Kota Yoshimura, Tzu-Chi Hsieh, Huiyang Ma +14
The Pauli limiting field of superconductors determines the maximal possible value of magnetic field at which superconductivity remains possible. For weak-coupling superconductors,…
Observation of Persistent Zero Modes and Superconducting Vortex Doublets in UTe
Nileema Sharma, Matthew Toole, James McKenzie +5
Superconducting vortices can reveal electron pairing details and nucleate topologically protected states. Yet, vortices of bulk spin-triplet superconductors have never been visuali…
Detecting Topological Superconductivity via Berry Curvature Effects in Spectral Functions
Yunxiang Liao, Yi-Ting Hsu
Experimental efforts on topological superconductivity (TSC) have primarily focused on the detection of Majorana boundary modes, while the bulk properties of TSC - particularly in t…
