Observation of an antiferromagnetic quantum critical point in high-purity LaNiO$_3$

Posted by klaurent Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan, Gensheng Wang, Deshun Hong | Summary: Amongst the rare-earth perovskite nickelates, LaNiO$_3$ (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-magnetic down to the lowest temperatures. It is believed that […]

A two-sided Faulhaber-like formula involving Bernoulli polynomials

Posted by klaurent MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero G., Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, , | Summary: We give a new identity involving Bernoulli polynomials and combinatorial numbers. This provides, in particular, a Faulhaber-like formula for sums of the form $1^m (n-1)^m + 2^m (n-2)^m + cdots + (n-1)^m 1^m$ for […]
