Quantum state tomography through multi-frequency Josephson effect
Xian-Peng Zhang, Ting-Rui Hu, Zhen-Biao Yang +2
Macroscopic quantum effects emerge when the coherent behavior of countless microscopic quantum states manifests collectively at a visible scale, as exemplified by the supercurrent…
Metalization of topological insulators
Xian-Peng Zhang, Yan-Qing Feng, Ji-Feng Shao +2
In modern condensed matter theory, phases of electronic matter--such as metals and insulators-are fundamentally distinguished by the presence or absence of charge-carrying quasipar…
Open quantum theory of magnetoresistance in mesoscopic magnetic materials
Xian-Peng Zhang, Xiangrong Wang, Yugui Yao
Magnetoresistance (MR) in magnetic materials arises from spin-exchange coupling between local moments and itinerant electrons, representing a challenging many-body open-quantum pro…
Nonvolatile optical switching of surface metallicity in 1T-TaSe2
Junde Liu, Liwen Su, Pei Liu +12
The surface of a quantum material provides a distinct electronic environment in which reconstruction can stabilize states absent from the bulk. However, whether light can persisten…
Andreev qubit readout from dynamic interference supercurrent
Xian-Peng Zhang, Chuanchang Zeng, Zhen-Biao Yang +2
Nondemolition protocols use ancilla qubits to identify the fragile quantum state of a qubit without destroying its encoded information, thus playing a crucial role in nondestructiv…
A Theory of Anisotropic Magnetoresistance in Altermagnets and Its Applications
Xian-Peng Zhang, Run-Wu Zhang, Xiaolong Fan +3
Altermagnets, a newly discovered class of magnets, integrate the advantages of both ferromagnets and antiferromagnets, such as enabling anomalous transport without stray fields and…
Quantum spin decoherence theory of magnetoresistance in mesoscopic ferromagnets and its applications
X. -P. Zhang, X. Wang, Y. Yao
Quantum decoherence is the key mechanism determining whether quantum effects can manifest in quantum computation and transport, and mastering decoherence is central to designing an…
Fermi sea and sky in the Bogoliubov-de Gennes equation
Xian-Peng Zhang, Yugui Yao
We develop a comprehensive logical framework for effectively handling the overcomplete basis set in the Bogoliubov-de Gennes equation that contains two orthonormal basis sets conju…
Colossal Layer Nernst Effect in Twisted Moiré Layers
Jin-Xin Hu, Chuanchang Zeng, Yugui Yao
In this work, we establish a theoretical analysis of the emergence of layer-contrasted Nernst response perpendicular to the direction of the temperature gradient in twisted moiré l…
