Algebraic approach to interacting quantum systems
... leads to more complex behaviour. Other kinds of order, not described by broken symmetries, are possible. For example, quantum orders of a topological nature distinguish the internal structure of the state without breaking any local symmetry, and its study is beyond the scope of the present paper [2] ...

Hyperfine interaction and spin decoherence in quantum dots
... was studied in atomic physics. In atoms, the interaction between the magnetic moments of the electrons and the nucleus leads to the hyperfine structure. The name hyperfine is historically due to the fact that the energy level splittings in atoms due to spin-orbit interaction were discovered first, a ...

Quantum Thermodynamics: A Dynamical Viewpoint
... In quantum thermodynamics, adiabats are modeled by time-dependent Hamiltonians. Typically, the external control Hamiltonian does not commute with the internal Hamiltonian. Infinitely slow operation is the prerequisite for the quantum and thermodynamic adiabatic conditions. Under these conditions, th ...

This sounds almost like one step too much at a time; we all know how rich and complicated the dynamics of the three-body problem is – can we really jump from three static disks directly to three charg ...

Eigenstate Phase Transitions
... The understanding of phase transitions has long been of interest. Recently eigenstate phase transitions have been discovered and studied; they are drastically different from traditional thermal phase transitions. In eigenstate phase transitions, a sharp change is exhibited in properties of the many- ...

Quantum Phenomena in Condensed Phase
... In semiclassical methods [2, 5, 37, 65, 69], all degrees of freedom are treated on the same footing, while hopefully still capturing the quantum character to a satisfactory extent. The quantum propagator is expressed as a weighted average of classical trajectories determined by a stationary phase an ...
