Discrete Time Crystals in Noninteracting Dissipative Systems

Gourab Das, Saptarshi Saha, Rangeet Bhattacharyya

Many-body quantum systems, under suitable conditions, exhibit time-translation symmetry breaking and settle in a discrete time crystalline (DTC) phase -- an out-of-equilibrium quan…

Trees with Prescribed Maximum Degree and Spectral Radius

Fengming Dong, Ruixue Zhang

It is well known that the spectral radius $ρ (T)$ of a tree $T$ with at least $3$ vertices satisfies $\frac{1}{4} ρ (T)^{2} + 1 < Δ (T) \leq ρ (T)^{2}$ , where $Δ (T)$ is the maximum degree of $T$ . Le…
