In traditional metals, the temperature (T) dependence of electrical resistivity vanishes at low
or high T, albeit for different reasons. Here, we review a class of materials, known as …

This review provides a comprehensive overview of current research on the structural,
electronic, and magnetic characteristics of the recently discovered high-temperature …

Although high-transition-temperature (high-T c) superconductivity in cuprates has been
known for more than three decades, the underlying mechanism remains unknown …

The pursuit of discovering new high-temperature superconductors that diverge from the
copper-based model,–has profound implications for explaining mechanisms behind …

Recently signatures of superconductivity were observed close to 80 K in La $ _ {3} $ Ni $ _
{2} $ O $ _ {7} $ under pressure [1]. This discovery positions La $ _ {3} $ Ni $ _ {2} $ O …

In contrast to conventional Fermi liquids where resistivity scales quadratically with
temperature, unconventional superconductors usually exhibit a normal-state resistivity that …

While the recent advances in topology have led to a classification scheme for electronic
bands described by the standard theory of metals, a similar scheme has not emerged for …

The discovery of superconductivity with a critical temperature of 80~ K in La $ _ {3} $ Ni $ _
{2} $ O $ _ {7} $ under pressure has received enormous attention. La $ _ {3} $ Ni $ _ {2} $ O …

Understanding electronic properties that violate the Landau Fermi liquid paradigm in
cuprate superconductors remains a major challenge in condensed-matter physics. The …

The signature feature of the 'strange metal'state of high-T c cuprates—its linear-in-
temperature resistivity—has a coefficient α 1 that correlates with T c, as expected were α 1 …
