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…
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…
Nonvolatile photoswitching of a Mott state via reversible stacking rearrangement
Junde Liu, Liwen Su, Pei Liu +12
Nonvolatile control of the Mott transition is a central goal in correlated-electron physics, offering access to fascinating emergent states and great potential for technological ap…
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…
