Abstract:
 Despite the special theory of relativity was discovered 120 years ago, how the temperature and chemical potential transform in the theory remain unknown.
 In a previous work, we established the law of temperature transformation. Here we present the Transformation Law of Chemical potential.
 The most disruptive change from $ \mu=0 $  to  $ \mu \neq 0 $ is the existence of a reservoir which sets up the chemical potential.
 Physically, the original bi-partite problem of the System + Observer at $ \mu=0 $ becomes a trinity problem of the Reservoir + System + Observer at $ \mu \neq 0 $.
 It is the relative motion between the system and the reservoir which dictates the  Transformation Law of the chemical potential.
 Combining with the results achieved in the previous work on the law of temperature transformation at $ \mu =0 $, we present the laws of both the temperature and the chemical potential transformation at $ T > 0, \mu \neq 0 $.
 Impacts on the thermodynamic zeroth to the third laws at $ T > 0, \mu \neq 0 $ in a moving sample are discussed.
 Applications to the finite temperature transitions in the quark-gluon plasma phase in QCD and the  zero temperature quantum phase transition in the neutron stars are given.
 Possible implications on the chemical potential of a moving quantum black hole are hinted through the AdS/CFT correspondence.
 Feasible experimental detections of fermionic topological phase transitions and Bose-Einstein condensations induced in a moving sample are analyzed.
 Differences between the experimental set-ups in condensed matter systems and those in particle physics are pointed out.

Speaker: Prof. Jinwu Ye(Great Bay University/Mississippi State University)
Prof. Ye received his Ph.D. from Yale University. Now he is a Professor at Mississippi state university.
Currently, he is a visiting professor at the newly found Great Bay university in Dongguan, Guangdong, China.
He is a condensed matter theorist  working on the interdisciplinary field of  condensed matter, quantum optics, cold atoms, non-relativistic quantum field theory, Turbulence and conformal field theory.
Recently, he has been particularly interested to explore possible deep connections among quantum/topological phases, Sachdev-Ye-Kitaev models and quantum black holes from material's point of views.
