Answer to Problem 1E

Solution:

a) The super-current Ic sin ϕ (t) as a function of t assuming that IIc is slightly greater than 1 and IIc >> 1 for a Josephson junction in the over-damped limit β = 0 is sketched.

b) The instantaneous voltage V(t) for both the cases is sketched.

Explanation of Solution

Josephson junctions are superconducting devices that are capable of generating voltage oscillations of extraordinarily high frequency. It consists of two closely spaced superconductors separated by a weak connection.

The Josephson relation in the over-damped limit β = 0 is given by

˙ϕ = IIc - sin ϕ

Here, Ic is the critical current.

Assuming that IIc is slightly greater than 1

Consider IIc = 1.1

˙ϕ = 1.1 - sin ϕ

The graph of ϕ vs. t is shown below

Assuming that IIc >> 1.

Consider IIc = 10,

ϕ = 10 - sin ϕ

The graph of ϕ vs. t is shown below.

b) Josephson voltage-phase relation is given by

V = 2e˙ϕ

Substituting ˙ϕ = IIc - sin ϕ, we get

V = 2e(IIc - sin ϕ)

Consider IIc = 1.1

The graph of voltage vs. ϕ is shown below.

A linear programming computer package is needed. Hanson Inn is a 96-room hotel located near the airport and convention center in Louisville, Kentucky. When a convention or a special event is in town, Hanson increases its normal room rates and takes reservations based on a revenue management system. A large profesional organization has scheduled its annual convention in Louisville for the first weekend in June. Hanson Inn agreed to make at least 50% of its rooms available for convention attendees at a special convention rate in order to be listed as a recommended hotel for the convention. Although the majority of attendees at the annual meeting typically request a Friday and Saturday two-night package, some attendees may select a Friday night only or a Saturday night only reservation. Customers not attending the convention may also request a Friday and Saturday two-night package, or make a Friday night only or Saturday night only reservation. Thus, six types of reservations are…
