Abstract Topologically nontrivial magnetic structures such as skyrmion lattices are well known in materials lacking lattice inversion symmetry, where antisymmetric exchange interactions are allowed. Only recently, topological multi-q magnetic texture

Abstract Uniaxial pressure provides an efficient approach to control charge density waves in YBa2Cu3Oy. It can enhance the correlation volume of ubiquitous short-range two-dimensional charge-density-wave correlations, and induces a long-range three-d

Exploiting a unique identification strategy based on inaccurate news analytics, we document an effect of news analytics on the market independent of the informational content of the news. We show that news analytics speed up the stock price and tradi

We analyze whether the growing importance of passive investors has influenced the campaigns, tactics, and successes of activists. We find activists are more likely to seek board representation when a larger share of the target company’s stock is he

We document that institutional investors, particularly hedge funds, decreased their holdings of larger stocks from 1980 to 2010 and increased their holdings of smaller stocks. Since 1990 institutions have underweighted, relative to market weights, th
