On the Sign of Fermion-Mediated Interactions
Qing-Dong Jiang
We develop a unified framework for understanding the sign of fermion-mediated interactions by exploiting the symmetry classification of Green's functions. In particular, we establi…
Experimental sensing quantum atmosphere of a single spin
Kehang Zhu, Zhiping Yang, Qing-Dong Jiang +8
Understanding symmetry-breaking states of materials is a major challenge in the modern physical sciences. Quantum atmosphere proposed recently sheds light on the hidden world of th…
Geometric Induction in Chiral Superconductors
Qing-Dong Jiang, T. H. Hansson, Frank Wilczek
We consider a number of effects due to the interplay of superconductivity, electromagnetism and elasticity, which are unique for thin membranes of layered chiral superconductors. S…
Axial Casimir Force
Qing-Dong Jiang, Frank Wilczek
Quantum fluctuations in vacuum can exert a dissipative force on moving objects, which is known as Casimir friction. Especially, a rotating particle in the vacuum will eventually sl…
Quantum Atmospherics for Materials Diagnosis
Qing-Dong Jiang, Frank Wilczek
Symmetry breaking states of matter can transmit symmetry breaking to nearby atoms or molecular complexes, perturbing their spectra. We calculate one such effect, involving the `axi…
Chiral Casimir Forces: Repulsive, Enhanced, Tunable
Qing-Dong Jiang, Frank Wilczek
Both theoretical interest and practical significance attach to the sign and strength of Casimir forces. A famous, discouraging no-go theorem states that "The Casimir force between…
