We probe the post-quench dynamics of a transverse-field Ising chain with tunable power-law interactions. The Hamiltonian of the model is represented as (ℏ = 1):
$$H=-{\sum}_{i < j}^{N}\,{J}_{ij}({\gamma }^{x}{\sigma }_{i}^{x}{\sigma…

Oxic microbial ferrihydrite reduction rates of Shewanella oneidensis and the potential for Fe mobilization in oxic sediments
Experimental medium
A liquid medium was prepared with deionized water, 10% v/v Luria Bertani broth (LB, Sigma Aldrich), and 20 mM PIPES (piperazine-N, N′-bis(2-ethanesulfonic) acid, Thermo Scientific). After adjusting the pH to ~ 7.1 using HCl…

Anisotropic Lorentz force effects on the Marangoni convection in liquid metal systems for fusion applications
Physical model
To model Marangoni convection within a three-dimensional, cubic cavity under the influence of a magnetic field, a physical model was established, as illustrated in Fig. 1. The cubic cavity is configured with each side having a…

The Higgs boson just revealed a new secret at the Large Hadron Collider
The ATLAS Collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon.
Since the discovery of the Higgs boson in 2012, physicists have made major strides in exploring its…
