This quantity is split into 5 components. The name of the amount refers basically to half I, that's by way of a ways the most important and includes papers discussing the basic questions of biology and similar mental and philosophical difficulties. Following the replica of papers delivered to booklet by way of Bohr, there's a separate Appendix to half I together with a few of Bohr's finest and great unpublished contributions during this quarter. The papers partly I span the final thirty years of Bohr's existence and reveal his nice curiosity in organic difficulties and his unremitting efforts to teach that biology can't be lowered to physics and chemistry.

half II includes articles of a extra basic cultural curiosity. a few of these exhibit that Bohr looked the complementary standpoint to be of price additionally outdoors the medical sphere.

half III includes the articles Bohr wrote concerning the nice Danish thinker Harald HГёffding. those brief papers are awarded in a piece on their lonesome due to the carrying on with dialogue within the heritage of technological know-how approximately HГёffding's attainable effect on Bohr's paintings in physics and his complete clinical approach.

half IV contains articles illuminating the historical past of twentieth century physics. Bohr had nice veneration for his predecessors and academics, and he ready those articles with nice care.

half V includes correspondence when it comes to the fabric in elements I via IV. As in prior volumes a list of appropriate unpublished manuscripts held on the Niels Bohr Archive constitutes an appendix to the total quantity.

**Many-Body Schrödinger Dynamics of Bose-Einstein Condensates **

At super low temperatures, clouds of bosonic atoms shape what's referred to as a Bose-Einstein condensate. lately, it has turn into transparent that many differing kinds of condensates -- so known as fragmented condensates -- exist. on the way to inform even if fragmentation happens or now not, it is important to unravel the total many-body Schrödinger equation, a job that remained elusive for experimentally appropriate stipulations for a few years.

**The Theory of Coherent Atomic Excitation (two-volume set)**

This e-book examines the character of the coherent excitation produced in atoms by way of lasers. It examines the distinct temporary version of excited-state populations with time and with controllable parameters comparable to laser frequency and depth. The dialogue assumes modest earlier wisdom of uncomplicated quantum mechanics and, in a few sections, nodding acquaintance with Maxwell's equations of electrodynamics.

**Electron-Electron Correlation Effects in Low-Dimensional Conductors and Superconductors**

Advances within the physics and chemistry of low-dimensional structures were rather fabulous within the previous few a long time. 1000s of quasi-one-dimensional and quasi-two-dimensional structures were synthesized and studied. the preferred representatives of quasi-one-dimensional fabrics are polyacethylenes CH [1] and engaging in donor-acceptor molecular crystals TIF z TCNQ.

47) with variational parameter d. 48) h/M ω0 , and the dimensionless interaction strength ¯ γ = |g| 4N √ . 07) or no minimum at all (for γ > γc ) [cf. Fig. 9]. In the latter case, the energy functional can only be minimized for r → 0 and the condensate collapses by evaporating atoms, a complicated process which has been recently analyzed experimentally [64]. Of course, for r → 0 the mean ﬁeld approach breaks down and a true many-body description is required. 1 Quantum Decay Rate out of a Metastable Well 41 v(r) 20 10 0 0 1 2 r Fig.

So far we have 1 not ﬁxed the centers of the instantons and, in fact, in the limit ω0 ¯hβ the total action is independent of their exact locations inside the interval [−¯ hβ/2, ¯ hβ/2]. This reﬂects again the time translation symmetry of the action that we have already discussed for the bounce orbit. To deal with this exact invariance, we follow a similar procedure: Select a representative out of the class of equivalent n-instanton paths and sum over the full set by integrating in a time-ordered manner over the locations of the centers.

Dynamics of Josephson Junctions In the basis of the charge eigenstates {|n , n ∈ Z} associated to the number of Cooper pairs having crossed the junction, the Hamiltonian of a JJ can be written as ∞ 1 HJ = − EJ (|n n + 1| + |n + 1 n|) . 22) 2 n=−∞ Here, EJ denotes the Josephson coupling energy between left and right domain and is related to their superconducting gaps, cf. Fig. 2. e. ˆ , ϕ] [N ˆ = i, related to the phase diﬀerence between the phases of the individual superconducting condensates. 22) reads ˆ J = −EJ cos(ϕ) H ˆ .
