Criticality around the Spinodal Point of First-Order Quantum Phase Transitions
Fan Zhang, Chiao Wang, H. T. Quan
Universality and scaling are hallmarks of second-order phase transitions but are generally unexpected in first-order quantum phase transitions (FOQPTs). We present a microscopic th…
Exact Work Distribution and Jarzynski's Equality of a Relativistic Particle in an Expanding Piston
Xianghang Zhang, Tingzhang Shi, H. T. Quan
We study the non-equilibrium work in a pedagogical model of relativistic ideal gas. We obtain the exact work distribution and verify the Jarzynski's equality. In the non-relativist…
Ergodicity Breaking and Scaling Relations for Finite-Time First-Order Phase Transition
Yu-Xin Wu, Jin-Fu Chen, H. T. Quan
Hysteresis and metastable states are typical features associated with ergodicity breaking in the first-order phase transition. We explore the scaling relations of nonequilibrium th…
Promoting Fluctuation Theorems into Covariant Forms
Ji-Hui Pei, Jin-Fu Chen, H. T. Quan
The principle of covariance, a cornerstone of modern physics, asserts the equivalence of all inertial frames of reference. Fluctuation theorems, as extensions of the second law of…
Optimal control theory for maximum power of Brownian heat engines
Jin-Fu Chen, H. T. Quan
The pursuit of achieving the maximum power in microscopic thermal engines has gained increasing attention in recent studies of stochastic thermodynamics. We employ the optimal cont…
Exploring quasiprobability approach to quantum work in the presence of initial coherence: Advantages of the Margenau-Hill distribution
Ji-Hui Pei, Jin-Fu Chen, H. T. Quan
In quantum thermodynamics, the two-projective-measurement (TPM) scheme provides a successful description of stochastic work only in the absence of initial quantum coherence. Extend…
