Abstract This year marks the 20th anniversary of discovery LaAlO 3 /SrTiO (LAO/STO) oxide heterointerfaces. Since their discovery, transition metal (TMO) interfaces have emerged as a fascinating and fast‐growing area research, offering variety unique exotic physical properties which has provided strong impetus for rapid advances actualization electronics. review revisits fundamental mechanisms accounting two‐dimensional (2D) conducting interfaces, how new models proposed to better account...
Owing to its inherent non-trivial geometry, the unique structural motif of recently discovered kagome topological superconductor AV3 Sb5 (A = K, Rb, Cs) is an ideal host diverse topologically phenomena, including giant anomalous Hall conductivity, charge order, density wave (CDW), and unconventional superconductivity. Despite possessing a normal-state CDW order in form chiral superconducting gaps structures, it remains unclear how fundamental atomic-level properties many-body effects Fermi...
Ferroelectric memristors, a type of nonvolatile resistive switching memory, have enormous potential in applications, including information storage and neuromorphic computing. The recent focus on two-dimensional (2D) ferroelectrics highlights their significance as promising platform for the next generation functional electronic devices.

The superconducting magnet wound by high-temperature (HTS) wires attracts extensive interest in high-magnetic field and at low temperature. However, different from the conventional low-temperature magnet, persistent operation of HTS with current switch is not commercial present because immature jointing technique between wires.

By studying angular dependences of the transport critical current density $({J}_{c})$, we demonstrate that strongest controllable improvement flux pinning takes place at $H\ensuremath{\Vert}c$, while highest ${J}_{c}$ occurs $H\ensuremath{\perp}c$ for artificial multilayers consisting three $R{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ ($R=\mathrm{Gd}$, Nd, and Eu) superconductors. It is found its anisotropy are tailored mainly due to collective...

We present a systematical study on the roles of electron correlation and spin-orbit coupling in isovalent Pd-doped superconductor SrPt$_3$P. By using solid state reaction method, we fabricated strong superconductors Sr(Pt$_{1-x}$Pd$_x$)$_3$P with correlated Pd dopant $4d$ orbital. As increasing concentrations without introducing any extra electron/hole carriers, superconducting transition temperature $T_c$ decreases monotonously, which suggests existence competition between state. In...
