Effects of dissipation and temperature on macroscopic quantum tunneling.

Macroscopic Quantum Effects in Biophysics and Consciousness

It is shown that investigations in the field of microwave resonance stimulation of the acupuncture system, as well as investigations of the interactions of consciousness with microscopic and macroscopic environment imply the existence of local and nonlocal macroscopic quantum biophysical effects, with great potential implications in medicine, psychology, biology, physics, engineering, and philo...

Macroscopic Effects of the Quantum Trace Anomaly

The low energy effective action of gravity in any even dimension generally acquires non-local terms associated with the trace anomaly, generated by the quantum fluctuations of massless fields. The local auxiliary field description of this effective action in four dimensions requires two additional scalar fields, not contained in classical general relativity, which remain relevant at macroscopic...

Macroscopic quantum effects in nanomechanical systems

– We investigate quantum effects in the mechanical properties of elastic beams on the nanoscale. Transverse quantum and thermal fluctuations and the nonlinear excitation energies are calculated for beams compressed in longitudinal direction. Near the Euler instability, the system is described by a one dimensional Ginzburg-Landau model where the order parameter is the amplitude of the buckling m...

On Quantum Computing with Macroscopic Josephson Qubits

The achievements of quantum computation theory, e.g. Shor’s factoring algorithm, motivate efforts to realize quantum computers. Among systems proposed for quantum computing macroscopic superconducting circuits of Josephson junctions appear promising for integration in electronic circuits and large-scale applications. Recently, a superconducting tunnel junction circuit was designed and a suffici...
