Spatially dispersive photogalvanic effects as a probe of quantum geometric tensor
Yicong Chen, Bumseop Kim, Senin Ahammed Akkara Paramban +8
Berry curvature and quantum metric of Bloch states govern a wide range of phenomena, yet unified experimental access to both remains limited. Here we show that light spatial-disper…

Quantum metric induced nonlinear transport in the hidden loop-current phase of kagome metal RbVSb
Jia-Chen Shi, Shupeng Xu, Utkarsh Khandelwal +4
A hidden low-temperature phase with possible loop-current order has been proposed in the kagome metals AVSb (A=K, Rb or Cs), but its experimental signatures remain subtle a…

Strong Chirality Suppression in 1-D correlated Weyl Semimetal (TaSe4)2I
Utkarsh Khandelwal, Harshvardhan Jog, Shupeng Xu +6
The interaction of light with correlated Weyl semimetals (WSMs) provides a unique platform for exploring non-equilibrium phases and fundamental properties such as chirality. Here,…
