Dynamics of Holstein Polaron in a Chain with Thermal Fluctuations

Numerical modeling is used to investigate the dynamics of a polaron in a chain with small random perturbations and under the influence of a constant electric field. In the semiclassical Holstein model the region of existence of polarons at the thermodynamic equilibrium state depe...

Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...
