Broken symmetry and propagating waves

 

Target phase waves for over-damped sine Gordon equation. These waves appear in the presence of thermal fluctuations as a result of competition between arrested and cycling states, close to the transition point.

The over-damped sine Gordon equation can be derived as a special case of the complex Ginzburg-Landau equation supplemented with a continuous-symmetry breaking term [1].

বন্ধু

 ভোর-রাতে, নিঃশব্দে সময় এসেছিল পাশে  জীবনের কিছু ক্ষণ নিয়ে অণুবীক্ষণ যন্ত্রে । হাতে হাত, পুরোনো দুই বন্ধুর দেখা বহুদিন পর; হঠাৎ করেই খুঁজে...
