Relationship between dwell, transmission and reflection tunnelling times

Autor: Mario Goto, Veríssimo Manoel de Aquino, Valdir C. Aguilera-Navarro, Donald H. Kobe, H. Iwamoto

Publikováno v: Journal of Physics A: Mathematical and General. 37:3599-3606

The transmission tunnelling time through a barrier is often defined as the probability that the particle is in the barrier divided by the transmission probability current density. The dwell time, the time the particle stays in the barrier, is commonl

Publikováno v: International Journal of Theoretical Physics. 41:877-886

Reflection and transmission times through a linear potential is studied by using the stationary phase method. The incident particle is described by a wave packet constructed from a momentum distribution δ(k′ − k) highly concentrated around a fix

Monte Carlo image representation

Autor: Hiromi Iwamoto, Mario Goto, V. C. Aguilera-Navarro, Veríssimo Manoel de Aquino

Publikováno v: American Journal of Physics. 69:788-792

A simple method for representing probabilistic systems visually based on a Monte Carlo approach is discussed. Applications are given for the hydrogen atom and the propagation of wave functions associated with tunneling through a potential barrier.

On the equivalence principle and gravitational and inertial mass relation of classical charged particles

Autor: Mario Goto, P L Natti, E R Takano Natti

We show that the locally constant force necessary to get a stable hyperbolic motion regime for classical charged point particles, actually, is a combination of an applied external force and of the electromagnetic radiation reaction force. It implies,

Tunneling time through a barrier using the local value of a 'time' operator

Autor: Hiromi Iwamoto, Donald H. Kobe, Mario Goto, V. C. Aguilera-Navarro

Publikováno v: Physical Review A. 64

A time for a quantum particle to traverse a barrier is obtained for stationary states by setting the local value of a ``time'' operator equal to a constant. This time operator, called the tempus operator because it is distinct from the time of evolut
