Liquid Crystal Ground States on Hyperbolic Cones
Cheng Long, David R. Nelson
We generalize the analytic theory and simulation models for liquid crystal ground states on conventional cones with positive apex Gaussian curvature and study liquid crystal ground…
Non-volatile Multistate Magnetic Switching via Spin-orbit Torque and Intrinsic Anisotropy
Fei Ye, Chunzheng Wang, Xue Zhang +6
While current-induced bistate spin-orbit torque (SOT) switching has been well established, deterministic electrical control of multiple magnetic states remains a central challenge…
Coexistence of Antiferromagnetic Spin Fluctuations and Superconductivity in La2SmNi2O7 Thin Films
Minhui Xu, Yibo Wang, Jia Liu +9
The interplay between magnetic fluctuations and superconductivity is fundamental for understanding unconventional high-temperature superconductors. In the recently discovered Ruddl…
Interplay of spin-orbit coupling and trigonal crystal field enhances superconductivity in (111)
Long Cheng, Jia Liu, Tongying Liu +10
In conventional superconductors, bulk physical properties typically degrade as the film thickness approaches the two-dimensional (2D) limit. Here in the (111) oriented LaAlO3/KTaO3…
Liquid Crystal Ground States on Cones with Anti-Twist Boundary Conditions
Cheng Long, David R. Nelson
Geometry and topology play a fundamental role in determining pattern formation on 2D surfaces in condensed matter physics. For example, local positive Gaussian curvature of a 2D su…
Observation of Quantum-Criticality-Class Crossover at the LaAlO/KTaO (111) Interface
Jia Liu, Long Cheng, Mingyue Zhang +3
In two-dimensional (2D) limit, the quantum fluctuation is significantly enhanced which could induce a quantum phase transition. Investigating the quantum criticality is an effectiv…
Angle-Resolved Magneto-Chiral Anisotropy in a Non-Centrosymmetric Atomic Layer Superlattice
Long Cheng, Mingrui Bao, Jingxian Zhang +19
Chirality in solid-state materials has sparked significant interest due to potential applications of topologically-protected chiral states in next-generation information technology…
Probing Interface of Perovskite Oxide Using Surface-specific Terahertz Spectroscopy
Yudan Su, Jiaming Le, Junying Ma +4
The surface/interface species in perovskite oxides play an essential role in many novel emergent physical phenomena and chemical processes. With low eigen-energy in the terahertz r…
Low-frequency Phonon at Perovskite Oxide Interface Studied by Surface-specific Nonlinear Terahertz Spectroscopy
Jiaming Le, Yudan Su, Junying Ma +4
The low-frequency collective excitations, which often occur in the terahertz or multi-terahertz spectral region, play an essential role in many novel emergent phenomena. Despite nu…
Violation of Ericksen inequalities in lyotropic chromonic liquid crystals
Cheng Long, Jonathan V. Selinger
By analyzing elastic theory for nematic liquid crystals, we distinguish three regimes of elastic constants. In one regime, the Ericksen inequalities are satisfied, and the ground s…
