Fourier-based methods for removing mesh anomalies from angle resolved photoemission spectra
Shouzheng Liu, Erica Kotta, Yishuai Xu +6
Recent improvements to spatial resolution in angle-resolved photo-emission spectroscopy (ARPES) have made it common to perform measurements with a very brief dwell time, for the pu…
Quantitative relationship between structural orthorhombicity, shear modulus and heat capacity anomaly of the nematic transition in iron-based superconductors
Joshua J Sanchez, Paul Malinowski, Jong-Woo Kim +2
Electronic nematicity in iron pnictide materials has been extensively studied by various experimental techniques, yet its heat capacity anomaly at the phase transition has not been…
Evidence for equilibrium excitons and exciton condensation in monolayer WTe2
Bosong Sun, Wenjin Zhao, Tauno Palomaki +14
A single monolayer of the layered semimetal WTe2 behaves as a two-dimensional topological insulator, with helical conducting edge modes surrounding a bulk state that becomes insula…
Coherent strong-coupling of terahertz magnons and phonons in a Van der Waals antiferromagnetic insulator
Qi Zhang, Mykhaylo Ozerov, Emil Vinas Boström +10
Emergent cooperative motions of individual degrees of freedom, i.e. collective excitations, govern the low-energy response of system ground states under external stimulations and p…
Electric control of a canted-antiferromagnetic Chern insulator
Jiaqi Cai, Dmitry Ovchinnikov, Zaiyao Fei +11
The interplay between band topology and magnetism can give rise to exotic states of matter. For example, magnetically doped topological insulators can realize a Chern insulator tha…
Apparatus Design for Measuring of the Strain Dependence of the Seebeck Coefficient of Single Crystals
Tiema Qian, Joshua Mutch, Lihua Wu +3
We present the design and construction of an apparatus that measures the Seebeck coefficient of single crystals under in-situ tunable strain at cryogenic temperatures. A home-built…
