In chemistry and biochemistry, chirality represents the structural asymmetry characterized by
nonsuperimposable mirror images for a material such as DNA. In physics, however, chirality …

One of the most celebrated accomplishments of modern physics is the description of
fundamental principles of nature in the language of geometry. As the motion of celestial …

The Berry curvature and quantum metric are the imaginary part and real part, respectively, of
the quantum geometric tensor, which characterizes the topology of quantum states. The …

Quantum geometry plays a pivotal role in the second-order response of PT-symmetric
antiferromagnets. Here we study the nonlinear response of 2D altermagnets protected by C …

Three mechanisms are known to contribute to second-order nonlinear current: Extrinsic
nonlinear Drude, Berry curvature dipole, and intrinsic Berry connection polarizability. Here …

Nonlinear transport phenomena offer an exciting probe into the band geometry and
symmetry properties of a system. While most studies on nonlinear transport have looked at …

It is known that intrinsic currents in magnetic metals often appear in the direction
perpendicular to the external field for linear and nonlinear responses. Distinct from three …

In ap–n junction, the separation of positive and negative charges leads to diode transport, in
which charge flows in only one direction. Non-centrosymmetric polar conductors are intrinsic …

The Hall response can be dramatically different from its quantized value in materials with
broken inversion symmetry. This stems from the leading Hall contribution beyond the linear …

The longitudinal nonreciprocal charge transport (NCT) in crystalline materials is a highly
nontrivial phenomenon, motivating the design of next generation two-terminal rectification …
