Magneto-optical 10 Cryostat for THz spectroscopy

许多重要的量子现象，如量子自旋液态和非常规超导性的出现，都与在零温度下发生的量子相变密切相关，量子相变是外部参数（掺杂、压力、场等）的函数。外部磁场的存在打破了时间反演对称性，这可能会引起新的物质状态，这将使用新的非线性太赫兹光谱方法来解决。中心目标是获得一个基本的了解非平凡的拓扑量子态的物质。

A rich variety of prominent quantum phenomena, such as the occurrence of quantum spin liquid states and unconventional superconductivity, are intimately related to the quantum phase transitions occurring at zero temperature as a function of an external parameter (doping, pressure, field, etc.). The presence of an external magnetic field breaks time reversal symmetry which may induce new states of matter which will be addressed using novel non-linear THz spectroscopy methods. The central aim is to obtain a fundamental understanding of non-trivial topological quantum states of matter.
