Quantum Time Crystal By Decoherence: Proposal With Incommensurate Charge Density Wave Ring
Keiji Nakatsugawa, Toshiyuki Fujii, Satoshi Tanda
We show that time translation symmetry of a ring system with a macroscopic quantum ground state is broken by decoherence. In particular, we consider a ring-shaped incommensurate ch…
Incommensurate Charge Density Wave as Quantum Space-Time Crystal
Keiji Nakatsugawa, Toshiyuki Fujii, Satoshi Tanda
A quantum time crystal (QTC) is a novel quantum mechanical ground state that was recently proposed by Wilczek. Although many QTC models have been proposed, it is not clear yet if s…
The effect of dissipation on quantum transmission resonance
Kohkichi Konno, Munehiro Nishida, Satoshi Tanda +1
Quantum transmissions of a free particle passing through a rectangular potential barrier with dissipation are studied using a path decomposition technique. Dissipative processes st…
