DOI: 10.1002/andp.202400291

Abstract: A theoretical study of an antiferromagnetically coupled spin system, specifically Cu3−X(X=As, Sb)$\text{Cu}_{3}-\text{X}(\text{X=As, Sb})$ , characterized by a slightly distorted equilateral triangle configuration is presented. Using the Heisenberg model with exchange and Dzyaloshinskii–Moriya interactions, g‐factors, and… read more here.

DOI: 10.1063/1.5111151

Abstract: In circuit quantum electrodynamics, measuring the state of a superconducting qubit introduces a loss channel which can enhance spontaneous emission through the Purcell effect, thus decreasing qubit lifetime. This decay can be mitigated by performing… read more here.

DOI: 10.1126/sciadv.adw8462

Abstract: The laws of thermodynamics strongly restrict the performance of thermal machines. Standard thermodynamics, initially developed for uncorrelated macroscopic systems, does not hold for microscopic systems correlated with their environments. We here derive an exact formula… read more here.
