Quantum physical phenomena are inherently different in dimensions lower than 3D. For instance, one can observe bizarre electronic quantum states in 2D with the properties of charge fractionalization, and in even lower dimension (1D) one can observe the conductance of a wire to be given by a single quantum corresponding to G=2e2/h. 

In this talk, I will describe a few low temperature experiment, all performed on some sort of a "chip", with the hope to elucidate bizarre quantum phenomena. These include:

1.     Our effort to detect bizarre particles that are neither boson or fermion, in 2D

2.      The 1D-1D Coulomb drag of electrons in two closed-pack quantum wires, separated by only ~15 nm,

3.     A nano-engineered quantum faucet (for real fluids!) and

4.     An extreme microscope that can take pretty pictures in16 tesla and at a temperature of 100 mK.

It's a lot of (quantum) fun!
